Problems & Risk

Business immigration risk can arise at any stage of the employment lifecycle, from recruitment and right to work checks through to sponsorship, changes in worker status, corporate restructuring and Home Office scrutiny. For employers, the consequences can extend well beyond the immediate immigration issue, affecting workforce continuity, recruitment plans, sponsor licence status, management time and wider business operations.

Effective risk management means looking at both prevention and response. Employers need robust systems, clear responsibilities and reliable escalation processes to identify weaknesses early, while also being able to investigate problems quickly, establish the facts and take proportionate corrective action when something goes wrong.

What this article is about

This guide looks at the principal areas of business immigration risk for UK employers, how those risks typically arise and the practical steps organisations can take to prevent, contain and resolve problems. It also considers how employers can strengthen their controls, prepare for Home Office scrutiny and reduce the likelihood of the same issues recurring.

Section A: Business Immigration Risk for Employers

1. What is business immigration risk?

Business immigration risk is the legal, regulatory and operational exposure that can arise when an organisation recruits, employs or sponsors workers who are subject to UK immigration control.

For employers, immigration compliance extends beyond obtaining visas for overseas recruits. The organisation may have responsibilities relating to right to work checks, sponsorship, record keeping, reporting, monitoring sponsored workers and responding appropriately when a worker’s circumstances change.

Risk can arise where these responsibilities are not met, but it can also arise when circumstances change after an employer has initially complied with the relevant requirements. A worker may move into a different role, their salary or working arrangements may change, their immigration permission may expire or be affected by a Home Office decision, or the employing organisation itself may undergo restructuring, a transaction or a change of ownership.

Some immigration risks concern an individual worker. Others can affect the organisation more broadly. A right to work problem may expose an employer to illegal working sanctions, while failures relating to sponsored workers can place the sponsor licence at risk. Serious, repeated or systemic compliance failures can also result in greater Home Office scrutiny of the organisation.

The practical significance of immigration risk therefore depends not only on whether a technical breach has occurred, but also on its nature, extent, duration and consequences.

2. Where do immigration risks arise?

Immigration risk can develop across the employment lifecycle.

At the recruitment stage, employers need to establish whether a candidate has permission to work in the UK and whether any restrictions apply to the work they can undertake. Where sponsorship is required, the employer must also determine whether the role and worker meet the relevant immigration requirements before assigning sponsorship.

Risk continues after employment begins. Employers may need to monitor time-limited permission, maintain required records and respond to changes affecting an individual’s right to work. Sponsors have additional duties concerning their sponsored workers and the organisation itself.

Common areas of exposure include:

• right to work checks that have not been completed correctly;
• failure to conduct required follow-up checks;
• employing someone outside the conditions of their immigration permission;
• incorrect or inappropriate sponsorship;
• changes to a sponsored worker’s role, salary, location or employment;
• failures to make required sponsor reports;
• incomplete or inaccurate immigration and personnel records;
• corporate or organisational changes affecting the sponsor licence;
• failure to respond appropriately when a worker’s immigration status changes; and
• weaknesses identified during Home Office compliance activity.

Problems may also arise because responsibility is divided between different parts of the organisation. Recruitment may obtain initial immigration information, HR may conduct right to work checks, managers may alter working arrangements, payroll may implement salary changes and another team may administer the Sponsor Management System.

Without effective communication between these functions, a decision made in one part of the business can create an immigration compliance problem elsewhere.

3. Why immigration problems can become business problems

The immediate legal issue is often only one part of the employer’s exposure.

An organisation that discovers a problem involving a sponsored worker may need to consider the worker’s immigration status, their right to continue working, sponsor reporting obligations and the employment law implications of any proposed action. If several workers are affected, the issue can quickly become a workforce and operational problem.

Home Office action can have still wider consequences. Depending on the circumstances, an employer may face financial penalties, restrictions on sponsorship or action against its sponsor licence. Losing the ability to sponsor workers can affect existing sponsored employees as well as future international recruitment.

Immigration problems can therefore affect:

• workforce availability;
• recruitment and workforce planning;
• retention of sponsored workers;
• the organisation’s sponsor licence;
• future access to overseas recruitment;
• management and HR resources;
• operational continuity;
• transactions and organisational change; and
• the employer’s relationship with the Home Office.

The potential impact makes early identification important. Employers that understand where immigration risk sits within their organisation are better placed to distinguish isolated administrative errors from problems requiring urgent investigation, remediation or formal response.

4. Identifying immediate and longer-term risk

When an immigration compliance issue is discovered, the first task is to establish what has actually happened rather than assuming the consequences.

The employer should identify the workers involved, the relevant immigration permissions or sponsorship arrangements, when the issue arose and whether it remains ongoing. It should also establish whether the problem is isolated or indicates a wider weakness in the organisation’s systems.

Immediate concerns may include whether an individual currently has the right to work, whether the employer needs to take action in relation to sponsorship or whether a Home Office deadline requires a response.

Longer-term concerns may involve weaknesses in right to work procedures, sponsor management, record keeping, internal communication or governance. Correcting the individual case without addressing the underlying process can leave the organisation exposed to the same problem recurring.

The appropriate response will therefore depend on both the specific immigration issue and the wider compliance environment in which it occurred. Effective immigration risk management requires employers to address both.

Section B: Right to Work & Illegal Working Risk

1. Employer responsibility for preventing illegal working

All UK employers have responsibilities for preventing illegal working, regardless of whether they hold a sponsor licence or employ sponsored workers.

The right to work regime requires employers to establish that an individual is permitted to undertake the work in question before employment begins. The check must also establish whether there are restrictions on the type of work the individual can undertake or the period for which they are permitted to work.

Where the prescribed right to work checking process is completed correctly before employment begins, the employer can establish a statutory excuse against liability for a civil penalty if the individual is subsequently found to be working illegally, subject to the applicable requirements.

For workers with time-limited permission, the employer may also need to carry out a further prescribed check at the appropriate time to maintain the statutory excuse. Immigration compliance therefore cannot always be treated as a one-off exercise completed during onboarding.

Employers also need to distinguish between a person having permission to be in the UK and having permission to undertake the particular work being offered. Immigration permission can carry conditions affecting employment, and a person who has permission to remain in the UK will not necessarily have unrestricted permission to work.

Right to work compliance should consequently form part of the organisation’s wider recruitment and workforce controls rather than being treated simply as an administrative document check.

The scope of the right to work civil penalty regime is also changing. From 1 October 2026, the regime is being extended beyond traditional employment relationships to specified worker and individual subcontractor arrangements and to certain online matching services, with additional provisions addressing liability within contractual chains.

Organisations that use contractors, subcontractors, casual workers, platform-based labour or other non-standard workforce models should therefore review their arrangements to determine whether they fall within the expanded regime and whether their right to work controls need to change.

2. How right to work compliance failures arise

Problems can arise even where an employer operates an established checking process.

Common risk areas include:

• failing to conduct a prescribed check before employment starts;
• conducting a check incorrectly;
• relying on evidence that does not establish a statutory excuse;
• failing to use the appropriate online or Home Office checking process;
• overlooking restrictions attached to an individual’s immigration permission;
• failing to carry out a required follow-up check;
• continuing employment after permission to work has ended without establishing a continuing statutory excuse;
• failing to retain the required evidence of the check; and
• operating inconsistent right to work procedures across different sites, departments or recruitment teams.

Employers can also encounter situations where an employee’s immigration position becomes uncertain during employment. For example, an employee may have made an application to extend or vary their immigration permission, may have an outstanding appeal or administrative review, or the employer may receive information suggesting that the employee’s previous evidence can no longer be relied upon.

These situations require careful assessment. An apparent visa expiry date does not, by itself, always establish whether the person currently has permission to work. An individual who made a valid application before their existing immigration permission expired may, depending on the circumstances, have continuing permission and an ongoing right to work while that application remains outstanding.

Equally, an employer should not continue employment merely because the individual previously passed a right to work check if the statutory excuse was time-limited and the employer is required to undertake a further check.

Where an individual cannot demonstrate their right to work through the normal prescribed checking routes, but the employer has reason to believe that they have an outstanding immigration application, appeal, administrative review or another qualifying basis for continuing permission, it may be necessary to use the Home Office Employer Checking Service.

Where the Employer Checking Service confirms the individual has the right to undertake the work in question, the employer may receive a Positive Verification Notice. Subject to the applicable requirements, this can provide a time-limited statutory excuse, requiring the employer to conduct a further check before that excuse expires.

The employer therefore needs to establish the individual’s current position using the appropriate prescribed checking process before deciding what action to take.

3. Illegal working and employer exposure

Illegal working can expose an employer to significant financial and regulatory consequences.

Where an employer is found to have employed someone who does not have the required permission to undertake the work in question, the Home Office may consider whether the employer has established a statutory excuse through the prescribed right to work checking process.

If the employer cannot establish a statutory excuse, it may be exposed to a civil penalty. Current maximum civil penalties can reach up to £45,000 per illegal worker for a first breach and up to £60,000 per illegal worker for repeat breaches.

The civil penalty regime is distinct from criminal liability. Criminal offences can arise in certain circumstances where an employer employs a person who is disqualified from employment by reason of their immigration status and the relevant statutory test concerning the employer’s knowledge or reasonable cause to believe is met.

Illegal working can also have consequences beyond the immediate penalty regime. For sponsor licence holders, evidence of illegal working can affect the organisation’s standing as a sponsor and may result in scrutiny of its wider recruitment, right to work and sponsorship arrangements.

An illegal working issue therefore needs to be considered from more than one perspective. The employer may need to assess the individual’s current right to work, potential civil penalty exposure, any criminal enforcement risk in sufficiently serious circumstances, sponsor licence implications and whether the circumstances reveal wider compliance weaknesses.

A single case can also expose systemic problems. If an investigation identifies one defective check, employers should consider whether the same procedure has been used for other workers and whether a wider audit is required.

4. Responding to a suspected right to work problem

Discovering a possible right to work failure requires a controlled response.

The employer should first establish the relevant facts, including what check was undertaken, when it was completed, what immigration evidence was relied upon, whether a statutory excuse was established and whether any subsequent check or Home Office verification has taken place.

It may then be necessary to determine the employee’s current immigration status and whether they presently have permission to undertake their role.

Employers should avoid treating uncertainty about immigration status as automatically establishing illegal working. The legal position may depend on matters such as an outstanding in-time immigration application, continuing immigration permission or the outcome of an Employer Checking Service verification.

At the same time, potential illegal working should not be ignored while the organisation continues business as usual. The immigration, employment and sponsorship implications may need to be considered together before deciding how the worker should be managed.

Employers should also avoid assuming that suspected immigration irregularity automatically requires immediate dismissal. Where the employee’s right to work is uncertain rather than conclusively absent, further verification may be required. Immigration compliance obligations and the employer’s employment law responsibilities should be considered together when determining the appropriate response.

Right to work procedures should also be applied consistently and without unlawful discrimination. Employers should not make assumptions about a person’s right to work because of their nationality, ethnicity, accent, name or other protected characteristic, and should follow the prescribed checking process consistently across their workforce.

Where a failure is confirmed, the employer should investigate why it occurred. Correcting the position of one employee will not adequately address the risk if the underlying problem is a defective onboarding process, a missed follow-up system, inadequate training or inconsistent implementation across the organisation.

5. Civil penalty objections and appeals

Receiving a civil penalty for illegal working does not necessarily mean that the Home Office’s decision cannot be challenged.

Depending on the circumstances, an employer may be able to object to a civil penalty, including where it contends that it is not liable, that it held a statutory excuse or that the amount of the penalty has been calculated incorrectly.

Where liability remains following the objection process, a further appeal may be available to the relevant court. The applicable procedure and deadlines are important, and employers considering a challenge should assess the Home Office’s evidence, their right to work records and the basis on which the penalty has been imposed.

The detailed requirements governing liability, mitigation, objections and appeals are considered in the specialist Illegal Working, Right to Work and Civil Penalties resources within this territory.

Section C: Sponsorship & Sponsor Licence Risk

1. Sponsoring workers creates ongoing compliance obligations

Holding a sponsor licence allows an organisation to sponsor eligible overseas workers, but it also places continuing compliance responsibilities on the employer.

Sponsor duties apply throughout the life of the licence and are intended to allow the Home Office to monitor both sponsoring organisations and the workers they sponsor. Employers need appropriate systems for maintaining records, monitoring sponsored workers, reporting relevant changes and ensuring that sponsorship continues to reflect the worker’s actual employment.

Risk can arise when there is a difference between the circumstances recorded for immigration purposes and what is happening in practice.

Changes to a sponsored worker’s role, duties, salary, working arrangements or employment may have immigration implications. Some changes may need to be reported through the Sponsor Management System, while others can affect whether the worker continues to satisfy the requirements of their immigration route or whether further immigration action is required.

Organisational changes can create similar problems. Changes to ownership, structure, trading arrangements or the employing entity may affect the sponsor licence and cannot safely be treated solely as corporate or HR matters.

The sponsor licence therefore needs active management. Employers should have processes that connect recruitment, HR, payroll, operational management and corporate decision-making with the organisation’s immigration compliance function.

2. How sponsor compliance problems arise

Sponsor compliance failures are not limited to deliberate breaches. Problems frequently arise because an organisation’s systems have not kept pace with its workforce, because responsibilities are unclear or because information relevant to sponsorship has not reached the people responsible for managing the licence.

Areas of risk can include:

• inaccurate or incomplete sponsor records;
• failures to retain documents required under the sponsorship regime;
• missed reporting obligations;
• changes to sponsored workers that have not been identified or reported;
• discrepancies between sponsored roles and the work actually being undertaken;
• salary or working arrangements that do not correspond with the basis on which sponsorship was granted;
• inadequate monitoring of sponsored workers;
• inappropriate assignment or use of Certificates of Sponsorship;
• failures relating to sponsor key personnel or Sponsor Management System administration; and
• organisational changes that have not been dealt with correctly under the sponsorship regime.

The significance of a compliance failure will depend on the circumstances. An isolated administrative mistake does not necessarily carry the same risk as repeated failures, serious breaches or evidence that the employer’s sponsorship systems are fundamentally ineffective.

Employers should nevertheless avoid assuming that apparently minor discrepancies are inconsequential. Home Office compliance activity can examine whether the organisation is meeting its sponsor duties in practice and whether its records are consistent with the circumstances of its sponsored workforce.

Home Office sponsor guidance also provides for action in circumstances involving a reasonable suspicion of non-compliance. Employers should therefore not assume that sponsor enforcement depends on the Home Office first establishing a completed breach to the criminal standard of proof. Where concerns are raised, the organisation may need to demonstrate through its records, systems and evidence that it has complied with its sponsorship responsibilities.

This makes accurate record keeping particularly important. A sponsor may know that it has acted appropriately, but if its Sponsor Management System history, personnel records, payroll information and operational evidence do not support that position, responding effectively to Home Office concerns can become considerably more difficult.

3. Sponsor licence enforcement

Where the Home Office identifies concerns about a sponsor’s compliance, a range of regulatory consequences can follow depending on the nature and seriousness of the issues and the relevant provisions of the sponsor guidance.

The sponsorship regime distinguishes between circumstances in which the Home Office may take particular action and circumstances in which specified action will follow where the relevant grounds are established.

Potential action can include changes to the organisation’s sponsor licence rating, restrictions on sponsorship activity, suspension of the licence or, in serious cases, revocation.

These outcomes should not be treated as a mandatory sequence. Sponsor enforcement does not necessarily progress from downgrading to suspension and then to revocation. Depending on the circumstances and the applicable grounds, the Home Office can take more serious action without first imposing a lesser sanction, and a sponsor licence can be revoked without first being suspended.

A sponsor licence suspension can have immediate operational significance. The organisation’s ability to undertake sponsorship activity may be restricted while the Home Office considers its position, and the employer will usually need to respond to the allegations or concerns raised within the applicable timeframe.

That response should be based on a careful examination of the Home Office’s allegations, the relevant sponsor requirements and the organisation’s evidence. Where compliance failures have occurred, employers should also consider whether corrective and remedial action can be demonstrated.

Revocation is more serious. Loss of the sponsor licence removes the organisation’s ability to sponsor workers under the affected licence and can have consequences for existing sponsored employees as well as future international recruitment.

Sponsor enforcement can therefore become a workforce continuity issue rather than remaining a regulatory matter between the organisation and the Home Office.

Where licence action is threatened or has already been taken, employers need to understand precisely what the Home Office alleges, establish the underlying facts, assess the evidence available to answer those concerns and identify any wider compliance weaknesses requiring remediation.

Detailed guidance on sponsor licence downgrading, suspension, revocation and other enforcement action sits within the separate Sponsor Licence Problems & Enforcement territory.

4. Wider risk to sponsored workers and the business

Sponsor licence problems can affect considerably more than the licence itself.

An organisation dependent on sponsored workers may have employees in operational, managerial or specialist positions whose ability to remain working for the business depends on continued sponsorship. Restrictions on the employer’s sponsorship capability can therefore create workforce shortages and disrupt recruitment plans.

The commercial exposure may be particularly significant where the organisation relies heavily on international recruitment or operates in a sector with persistent skills shortages.

Employers facing sponsor compliance concerns should therefore assess both the regulatory problem and its operational consequences. Relevant questions can include how many sponsored workers may be affected, which roles they perform, whether recruitment plans depend on further sponsorship and what contingency measures may be required.

The existence of sponsor problems can also indicate weaknesses elsewhere in the organisation’s immigration controls. For example, inaccurate personnel records, poor communication between HR and operational managers or weak monitoring processes may affect both sponsorship compliance and right to work management.

Effective remediation should therefore address the cause of the failure rather than simply the individual issue identified by the Home Office.

For employers, the objective is not merely to retain the sponsor licence. It is to maintain a sponsorship system capable of supporting international recruitment while meeting the organisation’s sponsor duties and withstanding Home Office scrutiny.

Section D: Risks Affecting Sponsored & Migrant Workers

1. Worker immigration status can create employer risk

An employee’s immigration position can change during employment. Where their ability to work depends on immigration permission, a change in status can create an immediate issue for both the worker and the employer.

The employer needs to understand whether the individual continues to have the right to undertake their role and, where they are sponsored, whether their circumstances remain consistent with the basis on which sponsorship was provided.

Potential problems can arise when immigration permission is approaching expiry, an extension or change of route is pending, an application has been refused, permission has been cancelled or the employer becomes aware of information that calls the worker’s immigration position into question.

These situations can be difficult because immigration status, right to work and sponsorship are related but distinct issues. A visa refusal, expiry date or other immigration development should not automatically be treated as establishing that the individual no longer has the right to work. The employer should establish the worker’s actual position before deciding what action is required.

Where several employees are affected by the same immigration issue, the risk can become operational. Changes to immigration rules, sponsorship arrangements or the organisation itself may affect a group of workers simultaneously, making early assessment important for workforce planning and business continuity.

2. Visa and sponsorship problems

Problems affecting an individual worker can arise before employment begins or during the employment relationship.

An overseas recruit may experience delays or refusal of an immigration application. A Certificate of Sponsorship may contain incorrect information. The proposed role may change after sponsorship has been assigned. An existing sponsored worker may move position, change duties, receive a different salary or adopt working arrangements that were not anticipated when they were sponsored.

Employers should avoid assuming that every change can simply be recorded internally.

Depending on the circumstances, a change may need to be reported to the Home Office, may require different sponsorship arrangements or may affect whether the worker continues to meet the requirements of their immigration route. In some circumstances, a change may require the worker to make a new immigration application before the revised arrangements can lawfully take effect.

Problems can also arise where the employer and worker make decisions independently. A worker may make an immigration application or experience a change in their personal circumstances without appreciating the implications for their employment or sponsorship. Equally, a manager may agree changes to a role without recognising that immigration approval was based on a particular job, salary, occupation or set of duties.

Effective immigration management therefore requires communication between the sponsored worker, HR, the sponsor licence team and operational management. Changes affecting a sponsored worker should be identified early enough for the immigration implications to be considered before the new arrangements are implemented wherever possible.

3. Expiring and uncertain immigration permission

Employers need reliable systems for identifying workers whose right to work is time-limited.

An approaching visa expiry does not necessarily mean employment has to end on the expiry date. A worker who made a valid immigration application before their existing permission expired may, depending on the circumstances, have continuing immigration permission and an ongoing right to work while that application remains outstanding.

Similar issues can arise where an eligible appeal or administrative review remains outstanding. The existence of an unresolved immigration process can therefore be relevant to whether the individual continues to have permission to work.

Conversely, an employer should not assume that a pending application automatically allows employment to continue. The circumstances of the application, the worker’s previous immigration permission and the conditions attached to that permission need to be considered.

Where the employer cannot establish a continuing statutory excuse using the normal prescribed right to work checking process, it may be necessary to use the Home Office Employer Checking Service.

Where the Employer Checking Service verifies that the individual has the right to undertake the work in question, the employer may receive a Positive Verification Notice. Subject to the relevant requirements, this can provide a time-limited statutory excuse, meaning a further prescribed check will generally be required before that excuse expires.

Uncertainty can also arise where the employer cannot verify a worker’s status using the information initially provided or where the Home Office has changed, cancelled or questioned the worker’s immigration permission.

The appropriate response is to establish the legal position through the relevant prescribed process rather than relying solely on documents, visa expiry dates or assurances from the employee.

Employers should also maintain evidence of the steps taken. Where a worker’s status later becomes the subject of Home Office scrutiny, the organisation may need to demonstrate how it established the individual’s right to work and why employment was permitted to continue.

4. Visa refusal, cancellation and loss of permission

A refusal or cancellation affecting an employee can have consequences for the employment relationship, but the consequences will depend on the worker’s circumstances.

The first issue is generally whether the individual currently retains permission to work. That question should be distinguished from whether their most recent immigration application has succeeded and whether they will ultimately be able to remain employed in the UK.

There may be options available to the worker to challenge an immigration decision, make a further application or otherwise address their immigration position. The available remedy will depend on the type of decision and the relevant immigration provisions.

Administrative review, for example, is not a general appeal against any immigration refusal. It is available only for eligible decisions and is concerned with whether a qualifying caseworking error has been made. Other decisions may carry different challenge rights or require a different immigration strategy.

The existence of a possible challenge or further application does not itself determine whether the person can continue working while that process is pursued. The worker’s current immigration permission and right to work need to be established separately.

For sponsored workers, employers should also consider whether the development triggers sponsor reporting obligations or otherwise affects the sponsorship relationship.

Premature action can create employment law risk, while continuing employment without establishing the right to work can create immigration risk. Employers therefore need to coordinate the immigration and employment aspects of the situation.

Where the position is unclear, early investigation can help the organisation determine whether employment can lawfully continue, whether temporary measures are appropriate, whether Home Office verification is required and what sponsorship action, if any, needs to be taken.

The specialist resources within the Problems & Risk hub provide more detailed guidance on individual visa, sponsorship and worker-status problems.

Section E: Business Change & Immigration Risk

1. Why organisational changes can affect immigration compliance

Business immigration compliance can be affected by changes to the organisation as well as changes involving individual workers.

Corporate transactions, restructuring, changes in ownership, transfers of employees and changes to the employing entity can all have immigration consequences. For sponsor licence holders, some changes have to be reported to the Home Office, while others can affect whether an existing sponsor licence remains appropriate or whether a new licence application is required.

The immigration implications can easily be overlooked where the transaction is being managed primarily as a corporate, employment, tax or commercial exercise.

A business may, for example, transfer employees between group companies without initially considering whether sponsored workers can move between the relevant entities under their existing immigration arrangements. A change in ownership may also have consequences for a sponsor licence even where the underlying business continues trading with little apparent operational change.

A sponsor licence is not an asset that can simply be transferred to a buyer or successor organisation. Where the identity, ownership or structure of the sponsoring organisation changes, the parties need to determine what the sponsorship rules require in the particular circumstances.

Relevant corporate changes can also trigger Home Office reporting obligations. Depending on the type of change, action may be required within prescribed timescales, including a 20-working-day period for specified changes under the sponsor guidance. Waiting until the wider transaction has been completed before considering sponsorship can therefore create avoidable compliance risk.

Immigration should form part of the planning process for significant organisational change wherever sponsored or other migrant workers may be affected.

2. Mergers, acquisitions and changes in ownership

Mergers and acquisitions can create particular risks for sponsor licence holders because sponsor licences are granted to specific organisations and cannot simply be transferred between businesses as part of a corporate transaction.

The immigration consequences will depend on the structure of the transaction, the entities involved, what happens to the employing business and whether sponsored workers transfer to another organisation.

Issues can include:

• changes in ownership or control;
• acquisition or disposal of a business;
• mergers and demergers;
• changes to the employing entity;
• transfer of sponsored workers;
• changes affecting existing sponsor licences;
• requirements for the buyer, successor or another entity to hold its own sponsor licence;
• Home Office reporting obligations; and
• deadlines for taking sponsorship-related action.

Due diligence should therefore identify sponsored workers and sponsor licences at an early stage.

The parties need to understand not only whether the target organisation holds a sponsor licence, but how that licence is being used, which workers depend on it, whether there are existing compliance concerns and whether the proposed transaction will alter the sponsorship arrangements.

Where a new sponsor licence is required, timing can become commercially important. The parties may need to consider the licence position alongside completion arrangements, employee transfers and the ability of the post-transaction organisation to continue sponsoring affected workers.

Failure to address these issues before completion can leave the resulting organisation trying to resolve sponsorship problems after the corporate change has already taken effect.

3. TUPE, restructuring and workforce transfers

Employee transfers can also have immigration implications.

Where workers transfer under TUPE or as part of another workforce restructuring, employers need to identify whether any affected employees are sponsored and determine how the transfer interacts with the sponsorship regime.

The fact that employment rights transfer under TUPE does not mean immigration and sponsorship requirements can be disregarded.

Equally, a TUPE transfer should not automatically be treated as meaning that existing sponsorship arrangements can never continue. The correct immigration treatment depends on the circumstances of the transfer, the entities involved and the applicable sponsor requirements.

The position can depend on the nature of the transfer, the relationship between the organisations and the sponsor status of the entities involved. Home Office reporting, changes to sponsorship arrangements or other action may be required.

Internal restructuring can create similar issues. Changes that appear relatively straightforward from an HR perspective may alter reporting lines, job duties, work locations, employing entities or other circumstances relevant to sponsored workers.

Employers planning a restructuring should therefore map the affected migrant workforce alongside the wider employee population and identify immigration consequences before implementing changes wherever possible.

4. Insolvency and cessation of trading

Financial distress can create additional immigration risk where a business employs sponsored workers.

Administration, receivership, liquidation, business sales, redundancies and cessation of trading can affect the organisation’s ability to continue meeting its sponsor duties. Sponsored workers may also face uncertainty about their employment and immigration position.

The immigration consequences should be considered alongside the insolvency and employment processes.

Relevant questions can include whether the sponsoring entity will continue to exist, whether the business or employees are transferring elsewhere, whether the receiving organisation holds the necessary sponsor licence and what reporting obligations arise.

Insolvency events can themselves trigger specific sponsor reporting requirements. Depending on the circumstances, the sponsor may need to report relevant events through the Sponsor Management System within the applicable timeframe, including within 20 working days for specified organisational changes.

Timing can be particularly important. Immigration options available before a business ceases trading or employment terminates may be different from those available afterwards.

Employers, purchasers, administrators and others dealing with a business that sponsors overseas workers should therefore identify the immigration position early rather than treating it as an issue to address after the commercial or insolvency arrangements have been finalised.

5. Managing immigration risk during business change

The most effective way to manage transactional immigration risk is to incorporate it into the change process from the outset.

Employers should identify:

• which entities hold sponsor licences;
• which employees are sponsored;
• which immigration routes are being used;
• who currently employs each sponsored worker;
• where those workers will sit after the proposed change;
• whether their roles, duties, salaries or locations will change;
• whether sponsor reporting is required;
• whether another entity needs to obtain or use a sponsor licence;
• whether any new sponsorship or immigration action is required; and
• the deadlines associated with any required action.

The objective is to understand the post-change immigration structure before implementing the corporate or workforce change.

Immigration due diligence can also reveal historical compliance issues. A transaction may expose missing sponsor records, unreported organisational changes, inappropriate sponsorship arrangements or discrepancies affecting sponsored employees. Those findings may need to be assessed and remediated as part of the wider transaction.

Where immigration issues are identified during due diligence, the parties should consider not only whether they can be corrected, but also whether they affect the transaction timetable, workforce continuity, sponsor licence position or post-completion integration.

For organisations with internationally recruited workforces, immigration should therefore form part of transaction planning, due diligence and post-completion integration rather than being treated as a separate administrative exercise after the event.

Detailed guidance on mergers and acquisitions, TUPE, restructuring, changes of ownership, insolvency and other organisational events sits within the separate Business Changes territory.

Section F: Home Office Scrutiny & Enforcement

1. Home Office compliance activity

UK employers can come under Home Office scrutiny for a number of reasons. Contact may arise through sponsor licence compliance activity, right to work enforcement, an application involving the organisation or information obtained by the Home Office from other sources.

For sponsor licence holders, compliance visits can take place before a licence is granted or while the licence is in operation. The Home Office can examine whether the organisation is meeting its sponsor duties and whether the systems described by the employer operate effectively in practice.

Compliance activity may be announced or unannounced, depending on the circumstances. Employers should therefore maintain their immigration systems on the basis that they may be required to demonstrate compliance without a lengthy period in which to prepare.

Scrutiny can also follow a particular event or concern. Discrepancies in information provided through the sponsorship system, intelligence relating to illegal working, problems involving sponsored workers, previous compliance failures or information arising from other Home Office activity can potentially result in closer examination.

Home Office scrutiny should not automatically be treated as confirmation that the organisation has breached its immigration obligations. However, once compliance activity begins, weaknesses in records, systems or explanations can become significant even where the original concern was relatively narrow.

Employers should therefore operate on the basis that their immigration records and processes may need to withstand external scrutiny. Preparing only after a Home Office visit has been announced or enforcement correspondence has been received can leave little time to identify weaknesses, establish the facts and determine the appropriate response.

2. What the Home Office may examine

The scope of Home Office scrutiny will depend on the reason for the compliance activity.

For sponsor licence holders, the Home Office may examine whether the organisation understands and complies with its sponsorship responsibilities. The assessment can extend beyond documents held in an immigration file to the way workers are actually recruited, employed and managed.

Areas of examination can include:

• right to work procedures;
• sponsored worker records;
• recruitment practices;
• Certificates of Sponsorship;
• job descriptions and actual duties;
• salary and payroll information;
• attendance and absence monitoring;
• reporting of relevant changes;
• Sponsor Management System records;
• sponsor key personnel;
• organisational records and trading activity; and
• the employer’s wider HR systems and compliance controls.

The Home Office may compare different sources of information rather than considering individual documents in isolation. Information recorded on a Certificate of Sponsorship may, for example, be considered alongside payroll data, contracts, HR records, organisational information and evidence of what the sponsored worker actually does.

Home Office officers may also speak with relevant personnel and sponsored workers. Differences between the organisation’s records, management explanations and workers’ accounts can create further questions even where the underlying issue initially appeared relatively limited.

Employers should therefore focus on whether their records accurately reflect what happens within the organisation rather than merely whether the required documents exist.

This is also why immigration compliance should not be confined to a central HR or sponsorship file. Where the reality of an employee’s role, salary, location or working arrangements differs from the information held by those responsible for immigration compliance, the organisation may have difficulty demonstrating that its sponsor duties are being met.

3. Responding to a Home Office compliance visit

A Home Office compliance visit can place considerable pressure on an organisation, particularly where it is unexpected.

Responsibility for dealing with immigration compliance activity should be established in advance. Reception staff, HR teams and relevant managers should understand who needs to be contacted if Home Office officers attend the premises.

The organisation should establish the nature of the visit, identify the appropriate internal personnel and maintain appropriate oversight of the information and documents being requested.

During a visit, employers need to understand the nature of the Home Office’s enquiries and ensure that information is provided accurately. Staff should avoid guessing where they do not know an answer or providing explanations that have not been verified.

Where documents or information are requested or supplied, the organisation should keep an appropriate record of what has been provided. This can become important if the Home Office subsequently raises concerns based on information obtained during the visit.

Employers should also be aware that the Home Office may be interested in operational reality rather than rehearsed answers. Managers and sponsored workers should therefore understand the organisation’s immigration procedures and their own circumstances, but they should not be coached to provide an artificial account of how the organisation operates.

After the visit, employers should consider whether any concerns were raised and whether further information is likely to be required. Notes should be made while events remain fresh, relevant records should be preserved and any potential compliance issues identified during the visit should be assessed promptly.

If possible failures have been identified, these should be investigated rather than simply waiting to see whether formal Home Office action follows.

The organisation may also need to assess whether an issue identified during the visit affects other workers or reveals a wider weakness in its immigration systems.

4. Home Office investigations and information requests

Not all scrutiny takes the form of an onsite visit.

Employers may receive correspondence requesting documents, explanations or information relating to their workers, sponsorship activity or immigration compliance arrangements.

The response should be managed carefully. Information supplied to the Home Office may be compared with previous sponsor reports, visa applications, Certificate of Sponsorship information, payroll records and other material available to the department.

Inconsistencies can therefore become significant.

Before responding, employers should establish the facts and identify the records relevant to the request. Where an error has occurred, the organisation should understand its nature and implications rather than attempting to explain it without first conducting an appropriate investigation.

Deadlines also need to be controlled. Home Office correspondence can require action within specified periods, and failure to respond appropriately can itself worsen the employer’s position or limit the opportunity to address the concerns raised.

A coordinated response is particularly important where several teams hold relevant information. HR, payroll, recruitment, operational management and the sponsor licence team may each hold different parts of the evidence required to establish what happened.

Employers should also consider whether the Home Office request concerns only the stated issue or whether the information being gathered could expose wider compliance concerns. A request relating to one sponsored worker, for example, may reveal discrepancies affecting other workers sponsored under the same process.

5. Potential enforcement consequences

The consequences of immigration non-compliance depend on the nature and seriousness of the problem and the enforcement regime involved.

Potential outcomes can include:

• requests for further information or corrective action;
• increased Home Office scrutiny;
• civil penalties for illegal working;
• action against the organisation’s sponsor licence;
• restrictions on its ability to sponsor workers;
• sponsor licence downgrading, suspension or revocation;
• consequences for affected sponsored workers; and
• criminal investigation or prosecution where the relevant criminal offence requirements are met.

Different enforcement regimes have their own legal tests, procedures and potential remedies. Employers should therefore identify precisely what type of Home Office action they are facing rather than treating all immigration enforcement as a single process.

In illegal working cases, the civil penalty regime is distinct from criminal liability. An employer that cannot establish a statutory excuse may face civil penalty exposure, while criminal employer liability depends on the separate statutory requirements, including the relevant test concerning knowledge or reasonable cause to believe that the individual is disqualified from employment by reason of their immigration status.

Likewise, sponsor licence enforcement operates under the sponsorship regime rather than the civil penalty framework. Depending on the applicable grounds, Home Office action can include downgrading, suspension or revocation, and more serious action does not necessarily have to be preceded by a lesser sanction.

Where a civil penalty for illegal working has been imposed, an employer may have a right to object to the penalty and, where liability remains following the objection process, may have a further right of appeal to the relevant court. Strict procedures and time limits apply, making early assessment important.

The wider commercial consequences of enforcement can also be substantial. An organisation that loses access to sponsorship may find that an immigration compliance problem develops into a recruitment and workforce continuity problem.

Where Home Office action has already begun, early assessment allows the employer to understand the allegations, preserve relevant evidence, identify weaknesses and determine the appropriate response.

Specialist guidance within the Problems & Risk hub deals separately with Home Office visits and audits, illegal working enforcement, civil penalties and sponsor licence action.

Section G: What Employers Should Do When Something Goes Wrong

1. Assess the immediate immigration risk

When an immigration problem is identified, the employer’s first priority should be to establish the facts and determine whether any immediate action is required.

The nature of the assessment will depend on the problem. A suspected right to work failure requires different analysis from an unreported sponsor change, a visa refusal or a Home Office compliance concern. Employers should avoid responding to the general seriousness of the situation before identifying the specific legal and compliance issues involved.

The initial assessment should establish:

• which workers are affected;
• their current immigration and right to work position;
• whether any workers are sponsored;
• what sponsorship information has previously been provided to the Home Office;
• when the problem arose;
• whether the issue is continuing;
• whether any reporting or other compliance deadline applies;
• whether the Home Office is already aware of the issue; and
• whether the problem appears isolated or potentially systemic.

Timing can be important. Some problems can be corrected or contained through prompt action, while delay may increase the employer’s exposure or allow the same failure to affect additional workers.

Where the Home Office has already contacted the organisation, any response deadline should be identified immediately and responsibility for managing the matter should be clearly allocated.

The employer should also distinguish between confirmed facts and assumptions. A visa expiry date, an apparent discrepancy in a personnel file or an allegation made by the Home Office may require investigation before the organisation can determine the legal consequences.

2. Contain the problem

Once the immediate position has been established, employers should consider what steps are required to prevent the problem from continuing or becoming more serious.

Containment does not necessarily mean terminating employment or suspending a worker. The appropriate action will depend on the facts and the individual’s immigration position.

Where there is uncertainty about a person’s right to work, for example, the employer may need to obtain further evidence, undertake the appropriate online check or use the Home Office Employer Checking Service before deciding whether the employee can continue working.

Where the Employer Checking Service confirms the individual’s right to undertake the work in question, a Positive Verification Notice may provide the employer with a time-limited statutory excuse, subject to the applicable requirements. Employers should therefore avoid treating uncertainty about immigration status as automatically establishing that the individual is working illegally.

Equally, suspected illegal working should not simply be ignored while employment continues indefinitely. The employer needs to establish the position using the appropriate prescribed process and act on the outcome.

A sponsorship problem may require the employer to review the worker’s Certificate of Sponsorship, immigration permission, role, salary, duties and employment arrangements before deciding whether a report, new immigration application or other action is necessary.

Where a process failure is identified, employers should also consider whether the affected procedure should temporarily be subject to additional oversight. If one incorrect right to work check has been discovered, for example, there may be value in reviewing other checks undertaken using the same process rather than assuming the problem concerns only one employee.

Containment should therefore address both the immediate case and the possibility of continuing organisational exposure.

3. Consider immigration and employment law together

Immigration compliance problems can create employment law issues, particularly where the employer is considering suspension, changes to duties or dismissal.

An employer should not automatically dismiss an employee merely because their immigration position has become uncertain. The organisation should first establish whether the individual currently has the right to work and whether further verification is available or required.

The distinction between an employee who conclusively no longer has permission to work and an employee whose immigration status is awaiting verification can be important.

Employers should therefore consider the immigration position alongside the employment relationship, contractual obligations and the appropriate employment procedure. Acting prematurely can create avoidable employment risk, while allowing employment to continue without properly establishing the individual’s right to work can create immigration exposure.

The employer should also ensure that its response is consistent and non-discriminatory. Decisions should be based on the individual’s actual immigration and right to work position rather than assumptions based on nationality, ethnicity or other protected characteristics.

4. Investigate and preserve evidence

A reliable factual record is important when responding to immigration compliance problems.

Employers should preserve relevant documents and establish a chronology of events. Depending on the issue, evidence may include:

• right to work check records;
• immigration status information;
• Employer Checking Service responses and Positive Verification Notices;
• Certificates of Sponsorship;
• Sponsor Management System records;
• visa application information available to the employer;
• employment contracts;
• job descriptions;
• payroll and salary records;
• attendance and absence records;
• recruitment documentation;
• correspondence with the worker;
• internal HR and management communications; and
• previous communications with the Home Office.

The purpose of the investigation is not simply to collect documents. The employer needs to understand what happened, who knew about it, what action was taken and whether the organisation’s procedures were followed.

Where records conflict, the discrepancy should be investigated rather than ignored. Differences between a Certificate of Sponsorship, employment contract, payroll record and the worker’s actual duties, for example, can be highly relevant to the assessment of sponsor compliance.

Evidence should also be considered in context. An apparent failure may have a legitimate explanation, while a seemingly minor administrative error may reveal a broader weakness when compared with other records.

Where Home Office action is already underway, preserving the evidence available at the time the problem was identified can be particularly important. Employers should avoid retrospectively altering records in a way that obscures what originally occurred. Corrections should be transparent and capable of being explained.

5. Correct and remediate compliance failures

Once the problem has been understood, the employer should determine whether corrective action is available and what remediation is required.

Corrective action addresses the immediate issue. Remediation addresses why the problem happened and how recurrence will be prevented.

Depending on the circumstances, immediate action might involve correcting records, making an appropriate sponsor report, undertaking a further right to work check, obtaining Home Office verification, obtaining missing information or changing an internal process.

Wider remediation may require:

• reviewing affected worker files;
• auditing similar cases;
• improving right to work procedures;
• correcting sponsor management processes;
• introducing additional approval controls;
• training HR or operational staff;
• changing reporting arrangements between departments;
• improving record keeping;
• clarifying responsibility for immigration compliance; or
• introducing periodic internal audits.

The distinction matters because correcting one case does not necessarily resolve the employer’s underlying exposure.

Where a compliance failure resulted from a systemic weakness, the Home Office may be interested in whether the organisation has identified the cause and implemented measures capable of preventing recurrence.

Remediation should be genuine and operational rather than simply documentary. Introducing a new policy will have limited value if the employees responsible for implementing it have not been trained or if the organisation has no mechanism for checking whether the new process is being followed.

6. Respond to the Home Office carefully

Where the Home Office is already involved, the employer’s response can materially affect how the problem develops.

Correspondence should be reviewed against the organisation’s records before substantive representations are made. Employers need to understand exactly what the Home Office is alleging or requesting and respond to those issues directly.

Information provided should be accurate, consistent and capable of being supported by evidence.

Employers should avoid speculative explanations. Where the organisation does not yet know why something happened, investigation is generally preferable to providing an assumption that later proves inconsistent with the evidence.

The response may also need to distinguish between accepting that an event occurred and accepting the Home Office’s interpretation of its significance. A factual discrepancy does not automatically establish every alleged compliance consequence.

Where mistakes have occurred, the organisation should consider how to explain both the circumstances and any corrective or remedial action taken.

Employers should also identify the particular enforcement regime involved. A sponsor licence suspension, civil penalty notice, information request and other Home Office enforcement action each operate under different procedures and can carry different response requirements, deadlines and challenge mechanisms.

Where a civil penalty has been issued, for example, the employer may have an objection and subsequent appeal route. Sponsor licence action is governed by the sponsorship regime and requires a different form of response. Understanding the nature of the decision is therefore fundamental to determining the appropriate strategy.

7. Consider the wider business impact

An immigration problem should also be assessed from an operational perspective.

Employers may need to understand whether the issue affects:

• an individual worker;
• a group of sponsored workers;
• the organisation’s wider right to work population;
• the sponsor licence;
• planned overseas recruitment;
• a pending corporate transaction;
• staffing of important projects or contracts; or
• the organisation’s ability to maintain business operations.

This broader assessment helps management determine the appropriate level of response.

A problem affecting one employee may be manageable through an individual immigration solution. A sponsor licence issue affecting a large sponsored workforce may require contingency planning at senior management level.

Where future recruitment depends on sponsorship, employers should also consider the effect that restrictions on the sponsor licence could have on vacancies that have not yet been filled. The operational impact of immigration enforcement can therefore extend beyond the employees immediately involved in the compliance problem.

The objective should be to resolve the immigration problem while protecting lawful employment, sponsorship capability and business continuity wherever possible.

Early intervention is generally more effective than allowing uncertainty to persist. Once the facts are known, employers can make informed decisions about containment, remediation, Home Office engagement and the steps needed to reduce further exposure.

Section H: Managing Business Immigration Risk

1. Immigration governance

Effective immigration compliance depends on governance as much as individual checks and reporting processes.

Employers need to know who is responsible for immigration compliance, how information reaches those individuals and how significant immigration risks are escalated within the organisation.

For sponsor licence holders, formal sponsor roles provide part of this structure, but allocating individuals as the Authorising Officer, Key Contact or Level 1 User does not by itself create an effective compliance framework.

The organisation also needs operational processes that allow those responsible for sponsorship to obtain accurate information from recruitment, HR, payroll, managers and other parts of the business.

Governance should address:

• overall responsibility for business immigration compliance;
• management of the sponsor licence;
• right to work responsibilities;
• ownership of Sponsor Management System activity;
• monitoring of sponsored workers;
• management of immigration and sponsorship deadlines;
• internal reporting of workforce changes;
• escalation of potential compliance failures;
• management of Home Office correspondence and visits;
• oversight of business changes affecting immigration; and
• periodic review of the organisation’s immigration controls.

The appropriate structure will depend on the size and complexity of the organisation. A smaller employer may have a relatively concentrated system managed by a small number of people. A larger organisation may need immigration controls operating across multiple sites, business units, HR teams and management structures.

In either case, responsibility needs to be clear.

One of the recurring causes of immigration compliance problems is the assumption that somebody else is dealing with the issue. A line manager may know that a sponsored employee’s role has changed but assume HR will identify the immigration implications. HR may assume the sponsor licence team has been informed. The sponsor licence team may have no knowledge of the change at all.

Effective governance closes these information gaps.

2. Internal immigration compliance controls

Immigration compliance should be supported by practical controls that operate throughout the employment lifecycle.

These controls should begin before employment starts and continue for as long as immigration considerations remain relevant to the worker or the organisation.

Depending on the employer, controls may include:

• prescribed right to work checks before employment begins;
• follow-up right to work checks where required;
• systems for identifying time-limited statutory excuses;
• procedures for using the Employer Checking Service where appropriate;
• retention of right to work evidence;
• pre-sponsorship assessment of roles and candidates;
• controls over the assignment of Certificates of Sponsorship;
• monitoring of sponsored worker salaries, duties and work locations;
• absence and attendance monitoring;
• processes for identifying reportable worker changes;
• processes for identifying reportable organisational changes;
• controls over Sponsor Management System access;
• document retention procedures;
• immigration input into restructuring and corporate transactions; and
• escalation procedures where a potential breach is identified.

Controls should reflect the organisation’s actual operating model.

A policy written for a single-site employer may not provide sufficient control for a business operating through multiple locations, decentralised management or different employing entities. Similarly, an organisation making extensive use of sponsored workers may require more sophisticated monitoring than an employer that sponsors only occasionally.

Workforce models also need to be reviewed as the legal framework changes. In particular, the extension of the right to work civil penalty regime from 1 October 2026 means organisations using specified worker arrangements, individual subcontractors or online matching services should consider whether their existing controls remain appropriate for the relationships through which labour is supplied or engaged.

Employers should therefore review immigration controls when the business changes rather than assuming that a system introduced several years earlier remains adequate.

3. Immigration compliance audits

Internal immigration audits can help employers identify problems before they result in Home Office enforcement.

An effective audit should test both documentation and operational practice.

Reviewing a sample of personnel files may identify missing right to work evidence or sponsorship records, but it may not reveal whether managers are changing sponsored workers’ duties without informing HR or whether payroll changes are reaching the sponsor licence team.

An audit can therefore examine areas such as:

• right to work records and checking procedures;
• follow-up check systems;
• Employer Checking Service use and Positive Verification Notices;
• sponsored worker files;
• Appendix D record-keeping requirements;
• Certificates of Sponsorship;
• Sponsor Management System records;
• worker roles and actual duties;
• salary and payroll information;
• work locations and working arrangements;
• attendance and absence monitoring;
• sponsor reporting processes;
• key personnel and SMS access;
• organisational reporting obligations;
• internal escalation procedures; and
• training and management awareness.

The audit should look for inconsistencies between different sources of information. A worker’s sponsorship records may appear correct in isolation but become problematic when compared with payroll, organisational charts, job descriptions or evidence of the work actually being performed.

Employers should also consider whether identified failures are isolated or systemic.

If several files contain the same type of error, the problem may lie with the underlying process rather than the individuals responsible for those particular records. Remediation should then address the system itself.

Audits can be particularly valuable before significant events, including sponsor licence applications, anticipated Home Office scrutiny, mergers and acquisitions, restructuring or substantial international recruitment programmes.

They can also form part of routine compliance governance. Periodic testing allows an employer to determine whether its procedures continue to work in practice rather than waiting for a Home Office compliance visit to expose weaknesses.

4. Training managers and HR teams

Immigration compliance is not solely the responsibility of the person operating the Sponsor Management System.

Managers can make decisions that have immigration consequences without realising it. They may agree a change in duties, salary, working location or reporting arrangements with a sponsored employee. Recruitment teams may alter a role during the hiring process. Payroll may identify a salary change that has not been communicated to the sponsor licence team.

Training should therefore be targeted at the responsibilities of different groups within the organisation.

HR and recruitment teams may need detailed training on right to work procedures, sponsorship processes and escalation of immigration issues. Line managers may require a simpler framework explaining which worker changes must be referred to HR or the sponsor team before implementation.

Relevant employees should also understand what to do if the Home Office contacts or visits the organisation.

Training should cover practical situations rather than simply reproducing immigration rules. Staff need to recognise the events that should trigger action.

Examples can include:

• a sponsored worker changing role;
• a proposed salary reduction;
• a worker moving to a different work location;
• long-term or unexplained absence;
• a worker approaching the expiry of time-limited immigration permission;
• difficulty completing a right to work check;
• receipt of an Employer Checking Service response;
• a change in company ownership or structure;
• a transfer of employees between entities;
• a request for information from the Home Office; or
• a Home Office compliance visit.

Training should also address discrimination risk. Right to work procedures need to be applied consistently and employers should avoid making assumptions about a person’s immigration status or right to work based on nationality, ethnicity, accent, name or other protected characteristics.

Where immigration responsibilities are shared across multiple sites or teams, refresher training can help maintain consistency and reduce the risk of local practices developing outside the organisation’s approved procedures.

5. Building an immigration risk management framework

A mature approach to business immigration compliance moves beyond reacting to individual visa and sponsorship problems.

The organisation should understand where immigration risk exists within its workforce, how those risks are controlled and what happens when a problem is identified.

A practical immigration risk management framework can be structured around five stages:

Identify → Assess → Respond → Resolve → Prevent

Identify means recognising the immigration issue early. This depends on effective right to work processes, sponsorship monitoring, internal communication and awareness of organisational changes.

Assess means establishing the facts and determining the legal, regulatory and operational significance of the problem. Employers should identify affected workers, relevant immigration permissions, sponsor obligations, statutory deadlines and potential Home Office exposure.

Respond means taking proportionate action to contain the immediate risk. This may involve further right to work verification, a sponsor report, investigation, preservation of evidence, management of a Home Office request or temporary operational measures.

Resolve means addressing the underlying immigration issue. Depending on the circumstances, this could involve correcting records, making an immigration application, responding to enforcement action, challenging a Home Office decision or implementing another appropriate solution.

Prevent means identifying why the problem occurred and improving the organisation’s systems to reduce the likelihood of recurrence.

This approach recognises that immigration risk is dynamic. Recruitment, workforce changes, visa expiry, corporate transactions, changes in immigration rules and Home Office enforcement activity can all alter an organisation’s risk profile.

Senior management should therefore have appropriate visibility of material immigration risks, particularly where the organisation relies heavily on sponsored workers or international recruitment.

The objective is not to eliminate every possibility of administrative error. It is to create a system capable of identifying problems quickly, demonstrating compliance, responding effectively to Home Office scrutiny and correcting weaknesses before they develop into significant regulatory or operational failures.

For employers using international workers, immigration compliance is ultimately part of workforce governance and business risk management. Strong systems protect not only the sponsor licence but also the organisation’s ability to recruit, retain and deploy the people it needs.

Section I: Conclusion

Business immigration risk extends far beyond obtaining visas or maintaining a sponsor licence. For UK employers, immigration compliance affects recruitment, workforce management, corporate change, employment decisions and the organisation’s exposure to Home Office scrutiny and enforcement.

Problems can arise through illegal working, defective right to work checks, sponsor compliance failures, changes affecting sponsored workers, visa and immigration status issues, corporate transactions or weaknesses in the systems used to manage an international workforce.

The consequences can also extend beyond the original immigration issue. Civil penalties, sponsor licence action and restrictions on sponsorship can affect an employer’s ability to recruit and retain workers, while more serious circumstances can result in criminal investigation or other enforcement action where the relevant statutory requirements are met.

Employers should therefore treat immigration compliance as an ongoing business risk rather than a series of isolated administrative tasks.

When something goes wrong, the immediate priority is to establish the facts. Employers need to understand the worker’s current immigration position, determine whether a statutory excuse or sponsor compliance issue arises, identify any reporting or response deadlines and assess whether the problem is isolated or evidence of a wider failure.

Action should then be proportionate to the circumstances. This may involve further right to work verification, use of the Employer Checking Service, sponsor reporting, correcting records, responding to the Home Office, challenging enforcement action or addressing the immigration position of an affected worker.

Employers should also consider immigration and employment law obligations together. Uncertainty about a worker’s immigration position should not automatically be treated as confirmation of illegal working, while potential immigration breaches should not be allowed to continue without investigation and appropriate action.

Where a failure is identified, resolving the individual case is only part of the response. Employers should determine why the problem occurred, whether other workers may be affected and whether recruitment, HR, payroll, sponsorship or management processes need to be strengthened.

The same principle applies to corporate change. Mergers, acquisitions, restructuring, TUPE transfers, changes in ownership and insolvency can all affect immigration compliance. Sponsor licences are not transferable, and relevant organisational changes can create reporting requirements or the need for new sponsorship arrangements. Immigration should therefore be considered during transaction planning rather than after the event.

Strong immigration governance helps employers move from reactive compliance to active risk management. Clear responsibilities, reliable right to work procedures, effective sponsor licence controls, internal communication, staff training and periodic compliance audits can identify weaknesses before they develop into serious problems.

This is particularly important as the right to work regime develops. From 1 October 2026, the civil penalty framework is being extended beyond traditional employment relationships to specified worker and individual subcontractor arrangements and certain online matching services. Organisations using non-standard workforce models should ensure their compliance framework reflects the expanded regime.

For employers, the objective is ultimately to maintain control over immigration risk: Identify, Assess, Respond, Resolve and Prevent.

Doing so protects more than immigration compliance. It helps safeguard the organisation’s workforce, sponsor licence, international recruitment capability and ability to respond confidently when the Home Office scrutinises its activities.

Section J: Frequently Asked Questions

 

 

1. What are the main business immigration risks for UK employers?

The main risks include employing individuals without the required right to work, failing to conduct compliant right to work checks, breaches of sponsor duties, problems affecting sponsored workers, failures to report relevant changes, Home Office compliance action and immigration issues arising from corporate or workforce changes.

The significance of these risks depends on the organisation and its workforce. An employer that relies heavily on sponsored workers may face substantial operational exposure if its sponsor licence is affected, while an organisation with a large or decentralised workforce may face greater risk from inconsistent right to work procedures.

Immigration risk should therefore be assessed in the context of the employer’s recruitment model, workforce structure, use of sponsorship and internal compliance systems.

2. What happens if an employer discovers a right to work problem?

The employer should establish the individual’s current immigration and right to work position before deciding what action is required.

An apparent problem does not necessarily mean the individual is working illegally. For example, a worker may have continuing immigration permission because of an outstanding in-time application, or the employer may need to obtain verification through the Home Office Employer Checking Service.

Where the Employer Checking Service confirms the individual has the right to undertake the work in question, a Positive Verification Notice may provide a time-limited statutory excuse, subject to the applicable requirements.

The employer should nevertheless act promptly. It should review the original right to work check, establish whether a statutory excuse exists, obtain any necessary verification and consider whether the problem indicates a wider weakness in its right to work procedures.

3. How much can an employer be fined for illegal working?

Under the current civil penalty regime, an employer can face a civil penalty of up to £45,000 per illegal worker for a first breach and up to £60,000 per illegal worker for repeat breaches.

Whether an employer is liable will depend on the circumstances, including whether it established a statutory excuse by carrying out the prescribed right to work check correctly and at the required time.

Civil penalties are separate from criminal liability. Criminal liability can arise in more serious circumstances where the relevant statutory requirements are met, including the applicable test concerning the employer’s knowledge or reasonable cause to believe that the person is disqualified from employment because of their immigration status.

4. Are the right to work rules changing in October 2026?

Yes. From 1 October 2026, the civil penalty and right to work regime is being extended beyond traditional employment relationships to specified worker and individual subcontractor arrangements and certain online matching service arrangements, with additional provisions concerning liability within contractual chains.

This is particularly relevant to organisations using contractors, subcontractors, casual labour, platform-based workers or other non-standard workforce models.

Businesses affected by the changes should review their workforce arrangements and right to work procedures to determine where the expanded regime applies and what additional controls may be required.

5. Can a sponsor licence be suspended for compliance failures?

Yes. The Home Office can suspend a sponsor licence where it has compliance concerns and the applicable grounds for suspension are met.

Suspension can restrict the organisation’s sponsorship activity while the Home Office considers its position. The sponsor will generally need to respond to the concerns raised within the applicable timeframe and should assess both the allegations and the evidence available to answer them.

Employers should not assume that sponsor enforcement always follows a fixed sequence. Depending on the relevant grounds and seriousness of the circumstances, the Home Office may take different forms of sponsor action, and a licence can be revoked without first being suspended.

6. Can the Home Office revoke a sponsor licence without suspending it first?

Yes. Suspension is not necessarily a mandatory stage before revocation.

The sponsor guidance distinguishes between circumstances in which the Home Office may take action and circumstances in which particular action will follow where the relevant grounds are established. Depending on the circumstances, the Home Office can revoke a sponsor licence without first suspending or downgrading it.

Employers facing sponsor licence action should therefore assess the specific grounds relied upon by the Home Office rather than assuming that an opportunity to resolve the issue through a lesser sanction will necessarily be available.

7. Can the Home Office carry out an unannounced compliance visit?

Yes. Home Office sponsor compliance activity can include announced or unannounced visits.

Employers should therefore maintain their immigration systems continuously rather than preparing them only when a compliance visit has been scheduled.

During a visit, the Home Office may examine records, systems and actual working practices and may speak with relevant personnel or sponsored workers. It can compare information obtained during the visit with Sponsor Management System records, Certificates of Sponsorship, payroll information, HR records and other evidence.

8. Can a merger, acquisition or restructuring affect a sponsor licence?

Yes. Mergers, acquisitions, changes in ownership, demergers, restructuring and workforce transfers can all have sponsor licence implications.

A sponsor licence is not transferable between organisations. The immigration consequences of a corporate change will depend on the structure of the transaction, the entities involved, what happens to the sponsoring organisation and whether sponsored workers transfer to another employer.

The change may trigger Home Office reporting obligations and, in some circumstances, another organisation may need to hold or obtain its own sponsor licence. Relevant sponsor reporting requirements can also operate to short timescales, including a 20-working-day period for specified organisational changes.

Employers should therefore consider immigration during transaction planning and due diligence rather than waiting until after completion.

9. Does TUPE automatically protect the immigration position of sponsored workers?

No. Employment law and immigration law need to be considered separately.

A TUPE transfer can have sponsorship implications even where the employee’s employment rights transfer to the new employer. The immigration treatment will depend on the circumstances of the transfer, the organisations involved and the applicable sponsor requirements.

Employers should identify sponsored workers during the planning stage and determine what sponsor reporting, licence or immigration action is required.

10. Does a visa expiry date automatically mean an employee must stop working?

Not necessarily.

An employee who made a valid immigration application before their existing permission expired may, depending on the circumstances, continue to have immigration permission and the right to work while that application remains outstanding.

Employers should establish the individual’s current right to work through the appropriate prescribed checking process rather than relying solely on the expiry date shown on previous immigration evidence.

Where the employer cannot establish the position through the normal checking route and the relevant conditions are met, it may need to use the Employer Checking Service and obtain a Positive Verification Notice.

11. Should an employer dismiss someone if their right to work is uncertain?

Employers should not automatically dismiss an employee merely because their immigration position is uncertain.

The organisation should first establish whether the individual currently has permission to undertake the work and whether further verification through the prescribed right to work process or Employer Checking Service is appropriate.

Immigration compliance and employment law responsibilities need to be considered together. Acting prematurely can create employment law risk, while allowing employment to continue without properly establishing the person’s right to work can expose the employer to immigration risk.

12. Can an employer challenge a civil penalty for illegal working?

Potentially, yes. An employer that receives a Civil Penalty Notice may be able to object to the penalty on the applicable grounds.

Depending on the circumstances, this may include disputing liability, relying on a statutory excuse or challenging the calculation of the penalty.

If the penalty remains following the objection process, a further appeal may be available to the relevant court. In England, Wales and Northern Ireland this is generally through the County Court, while in Scotland the relevant forum is the Sheriff Court.

Strict procedures and deadlines apply. Employers considering a challenge should therefore review the notice, their right to work records and the Home Office’s stated basis for liability promptly.

13. Can an employer challenge other Home Office immigration decisions?

The available challenge depends on the type of decision.

Some immigration decisions may carry a right of administrative review or appeal, while other decisions may be capable of challenge through judicial review where the relevant legal requirements are met.

Administrative review is not a general reconsideration procedure. It applies to eligible decisions and is principally concerned with specified caseworking errors.

Judicial review is concerned with the lawfulness of a decision, action or failure to act rather than providing a general merits-based appeal. Whether judicial review is appropriate can also depend on whether an adequate alternative remedy or another appropriate forum is available.

Employers should therefore identify the specific decision and available remedy before determining how it should be challenged.

14. How can employers reduce business immigration risk?

Effective immigration risk management combines compliant right to work procedures, active sponsor licence management, reliable record keeping, clear internal responsibilities, staff training and periodic auditing.

Employers should also ensure that immigration considerations form part of wider business processes, including recruitment, changes to employee roles, payroll changes, restructuring, mergers and acquisitions and workforce planning.

A practical framework is to Identify, Assess, Respond, Resolve and Prevent. This allows the organisation not only to deal with individual problems but also to identify why they occurred and strengthen its systems against future compliance failures.
