ENTITY Business Imm ABC

Section A: What this article is about

UK employers increasingly rely on international talent to fill skills gaps, support growth, transfer specialist personnel and build globally connected workforces. Business immigration is the legal and operational framework that allows organisations to recruit, sponsor, transfer and employ overseas nationals in the UK.

For employers, business immigration is wider than the worker’s visa application. It includes deciding whether sponsorship is required, obtaining and managing a sponsor licence, assessing whether a role can be sponsored, selecting the correct immigration route, assigning Certificates of Sponsorship, conducting right to work checks and complying with ongoing Home Office duties.

It also affects ordinary business decisions. Recruitment, salary changes, promotions, hybrid working, corporate restructures, mergers and acquisitions, redundancies and international assignments can all have immigration consequences.

This guide explains the principal UK business immigration routes and employer requirements, how sponsorship works, the costs and timescales involved, how businesses should manage immigration during employment and what happens when immigration or sponsor compliance problems arise.

Section B: Employing workers in the UK

UK employers can recruit people of any nationality, provided the individual has immigration permission that allows them to undertake the work being offered.

The first immigration question in an international recruitment exercise is therefore not necessarily which visa the employer should sponsor. It is whether the candidate already has the right to work in the UK and, if so, whether their existing immigration status permits the proposed employment.

Some workers require employer sponsorship. Others can work without sponsorship because of their nationality or the immigration permission they already hold.

Understanding that distinction can save employers from unnecessary sponsorship while helping to identify cases where immigration action is required before employment can begin.

1. Can UK businesses employ overseas workers?

Yes. UK businesses can employ overseas nationals where the individual has the required permission to work in the UK.

How that permission is obtained depends on the worker’s circumstances.

An individual may already have unrestricted or sufficiently broad permission to work. Another candidate may need to obtain a sponsored work visa before they can take up the role.

The employer should establish the individual’s immigration position as part of the recruitment and onboarding process and carry out a compliant right to work check before employment begins.

Where sponsorship is required, additional considerations include whether:

• the employer holds an appropriate sponsor licence
• the immigration route permits sponsorship for the proposed role
• the job meets the relevant occupation requirements
• the proposed salary satisfies the applicable rules
• the worker meets the requirements of the immigration route
• a Certificate of Sponsorship can be assigned
• the worker can obtain the necessary immigration permission before starting work

Employers should not allow a candidate to begin work merely because a visa application has been submitted. The organisation needs to establish that the individual has a lawful right to undertake the work at the point employment starts.

2. Does every overseas worker need a UK work visa?

No. Nationality alone does not determine whether an individual needs employer sponsorship.

Some people have immigration status that allows them to work in the UK without being sponsored by the employer.

Depending on their circumstances, this can include people with:

• British or Irish citizenship
• indefinite leave to remain or settled status
• status under the EU Settlement Scheme
• dependant immigration permission carrying work rights
• a Graduate visa
• a Global Talent visa
• a High Potential Individual visa
• certain family visas
• other immigration permission allowing the proposed employment

The precise work conditions attached to the person’s immigration status need to be checked.

An employer should therefore avoid treating “international worker”, “visa holder” and “sponsored worker” as interchangeable terms.

A person can be subject to UK immigration control and still have permission to work without sponsorship from their employer.

3. Recruiting workers who already have permission to work

Candidates who already have suitable UK immigration permission can often be recruited without the employer using its sponsor licence.

This can make recruitment faster and avoid some of the costs associated with sponsorship.

The employer still needs to establish that the person’s permission allows the proposed work and complete the appropriate right to work check.

It should also understand whether the permission is time limited.

For example, a candidate may currently have permission to work but only until a specified date. The employer will need to consider what happens when that permission approaches expiry.

Possible outcomes include the worker:

• extending their existing immigration permission
• switching into another immigration category
• becoming eligible for settlement
• requiring employer sponsorship
• losing the right to continue working if further permission is not obtained

Employers recruiting workers with time-limited immigration status should therefore have systems for monitoring relevant expiry dates.

4. When is employer sponsorship required?

Employer sponsorship is generally relevant where an individual needs to qualify under a sponsored work route to undertake the proposed employment.

The Skilled Worker route is the principal sponsored route used by UK employers for long-term recruitment, although other sponsored routes apply to particular categories of workers and assignments.

Sponsorship involves two connected immigration relationships.

First, the employer must be authorised by the Home Office to sponsor workers under the relevant route. This is achieved through the sponsor licensing system.

Second, the employer must sponsor the particular worker for an eligible role, normally by assigning a Certificate of Sponsorship containing information about the proposed employment.

The worker then uses the Certificate of Sponsorship as part of their immigration application.

Holding a sponsor licence does not itself give the worker permission to work in the UK, and assigning a Certificate of Sponsorship does not amount to the grant of a visa.

The basic sequence is:

Sponsor licence -> eligible role -> Certificate of Sponsorship -> worker visa application -> immigration permission -> right to work check -> employment

Each stage performs a different function within the sponsorship system.

5. Can an employer recruit someone who is already in the UK?

Potentially, yes.

A candidate who is already in the UK may have immigration permission that allows them to take the proposed job immediately, or they may need to make a further immigration application before starting the role.

The employer should establish:

• what immigration permission the person currently holds
• whether that permission allows the proposed work
• when the permission expires
• whether there are restrictions on the work they can undertake
• whether they need to switch immigration category
• whether the relevant immigration route permits an in-country application
• when they can lawfully start the new employment

This can be particularly relevant when recruiting international graduates, dependants, workers changing sponsors or individuals moving between immigration categories.

Where the candidate needs Skilled Worker sponsorship to change employer, the new employer will normally need to sponsor the individual for the new role and the worker will need the required immigration permission for that employment.

6. Right to work checks

Every UK employer has responsibility for preventing illegal working.

A compliant right to work check should be completed before employment starts, regardless of whether the person is British, holds an unsponsored visa or has been sponsored by the organisation.

The method used to conduct the check depends on the evidence available and the individual’s immigration status.

For many people with digital immigration status, the employer will use the Home Office online right to work service. The worker provides a share code which allows the employer to access the relevant information and confirm their right to work.

The employer should check that:

• the evidence relates to the person being recruited
• the individual has permission to undertake the work being offered
• any restrictions are understood
• the check is completed in the prescribed manner
• the required evidence of the check is retained

Where the individual’s permission to work is time limited, a further check may be required before the existing permission expires.

Right to work and sponsorship are related but separate employer obligations. Assigning a Certificate of Sponsorship or receiving confirmation that a visa has been granted does not remove the requirement to carry out the appropriate right to work check.

7. What happens if a worker does not have permission to work?

An employer should not employ an individual where the person does not have the required right to work in the UK.

Illegal working can expose the organisation to significant immigration, financial and operational consequences.

Depending on the circumstances, these can include:

• a civil penalty for employing an illegal worker
• criminal liability in more serious cases
• Home Office investigation
• sponsor licence compliance action
• suspension or revocation of a sponsor licence
• disruption to the wider sponsored workforce
• reputational damage

Civil penalties can reach £45,000 per illegal worker for a first breach and £60,000 per illegal worker for repeat breaches, subject to the statutory scheme and the circumstances of the case.

The consequences can extend beyond the individual worker.

For a licensed sponsor, evidence of inadequate right to work practices or illegal working may cause the Home Office to question whether the organisation is capable of meeting its wider sponsorship duties.

Employers should therefore treat right to work as part of recruitment governance rather than simply an administrative check completed on an employee’s first day.

8. Employer decision: sponsorship or existing work permission?

Before beginning a sponsorship process, the employer should answer three questions:

Does the candidate already have permission to work?

If yes, determine whether that permission covers the proposed role and how long it remains valid.

If not, is there an immigration route that allows the candidate to work without employer sponsorship?

The individual’s circumstances may provide access to an unsponsored route.

If sponsorship is required, can the employer sponsor this particular role and worker?

Only at this stage does the assessment move into sponsor licence status, occupation eligibility, salary requirements, Certificates of Sponsorship and the worker’s visa application.

Making this distinction early helps employers avoid unnecessary sponsorship and identify immigration barriers before recruitment decisions become difficult to reverse.

Section C: Recruiting international workers

International recruitment requires employers to consider immigration status alongside the usual assessment of skills, experience, salary and suitability for the role.

The immigration assessment should take place early enough to identify whether the candidate can work under their existing status or whether further permission, including employer sponsorship, will be required.

Where sponsorship is needed, the employer also needs to establish whether the proposed role is capable of being sponsored and whether the recruitment package can satisfy the requirements of the relevant immigration route.

1. Check the candidate’s immigration status

The starting point is to establish the candidate’s current immigration position.

A candidate may:

• already have an unrestricted right to work in the UK
• hold time-limited immigration permission allowing the proposed employment
• have permission to work subject to particular restrictions
• need to switch immigration category before taking the role
• require employer sponsorship
• be applying from outside the UK and need entry clearance before travelling to work

The answer affects the recruitment process.

Where the candidate already has suitable permission, sponsorship may not be necessary. Where their permission is restricted or approaching expiry, the employer may need to consider a longer-term immigration strategy even if the person can initially be recruited without sponsorship.

Employers should also avoid making assumptions based on nationality, residence in the UK or possession of a previous visa. The relevant issue is the immigration permission held by the individual and whether it permits the work being offered.

2. Assess the proposed role

Where sponsorship is being considered, the role itself needs to be assessed against the requirements of the relevant immigration route.

For Skilled Worker sponsorship, this involves identifying the appropriate occupation code and determining whether the occupation is eligible under the applicable rules.

For Certificates of Sponsorship assigned from 22 July 2025, Skilled Worker roles generally need to be at RQF level 6 or above unless an applicable exception applies, including relevant shortage-list or transitional provisions. The requirement concerns the skill level of the job; it does not mean that the individual worker must necessarily hold a degree.

The assessment should reflect the actual job.

Job titles alone are not necessarily sufficient. Two employers may use the same title for roles involving materially different duties, while different job titles may describe substantially similar work.

The employer should therefore consider factors including:

• the principal duties of the role
• the skills and responsibilities involved
• the level of the position
• the proposed salary
• working hours
• the worker’s place of work
• reporting arrangements
• the organisation’s business activities
• how the role fits within the wider workforce

These details may become relevant not only when sponsorship is initially assessed but also if the Home Office later examines whether the sponsored employment reflects the information recorded on the Certificate of Sponsorship.

3. Determine whether sponsorship is required

Once the worker’s existing immigration status and the proposed role are understood, the employer can determine whether sponsorship is necessary.

There are broadly three possibilities.

The candidate can work without sponsorship.

Their existing immigration permission allows them to undertake the proposed employment.

The candidate can obtain permission through an unsponsored route.

Depending on their circumstances, the worker may qualify under an immigration category that gives them permission to work without being sponsored by the employer.

The candidate needs employer sponsorship.

The employer will then need to identify an appropriate sponsored work route and satisfy the requirements applying to the organisation, role and worker.

This assessment matters commercially because sponsorship introduces additional cost, administration and compliance responsibilities.

It can also affect recruitment timescales. An employer that discovers only after making an unconditional offer that sponsorship is required may find that the intended start date cannot be achieved.

4. Identify the correct immigration route

Where further immigration permission is required, the employer and worker need to identify the route that best reflects the proposed arrangement.

The Skilled Worker route is commonly used for long-term recruitment into eligible UK roles, but it is not the only option.

Depending on the circumstances, alternatives may include:

• Health and Care Worker
• Global Business Mobility routes
• Scale-up
• International Sportsperson
• Temporary Worker routes
• Global Talent
• High Potential Individual
• Graduate
• family or dependant routes carrying work permission
• other immigration categories permitting employment

The appropriate route depends on factors such as the nature of the role, the worker’s circumstances, the intended duration of the UK assignment, the relationship between overseas and UK organisations and whether settlement in the UK is an objective.

Route selection can have consequences beyond the immediate visa application.

For example, two routes may both allow an individual to undertake work in the UK but differ in relation to sponsorship requirements, costs, maximum duration, flexibility, dependants and eligibility for settlement.

Employers should therefore avoid choosing a route solely because it appears to offer the quickest immediate solution.

5. Consider occupation and skill requirements

Sponsored work routes can impose requirements relating to the type and level of work being undertaken.

The employer may need to identify the occupation code that most accurately describes the proposed role and confirm that the occupation is eligible for sponsorship under the relevant route.

For Skilled Worker applications under the post-22 July 2025 framework, the general skill threshold is RQF level 6, subject to applicable exceptions and transitional arrangements. Employers should check the current eligible occupation tables and any relevant Immigration Salary List, Temporary Shortage List or transitional provision at the time of sponsorship.

The occupation code can affect:

• whether the role can be sponsored
• the applicable salary requirements
• the relevant going rate
• whether particular concessions or transitional provisions apply
• how the Home Office assesses the proposed employment

Selecting an occupation code because it produces a more favourable immigration outcome, rather than because it genuinely reflects the role, can create compliance problems.

The job description, employment contract, organisational structure and Certificate of Sponsorship should therefore present a coherent picture of the employment being offered.

6. Check the salary before making the offer

Salary should be considered before the employer finalises the recruitment package.

For a standard Skilled Worker application under the current framework, the usual starting point is that salary must meet both the applicable general threshold and the relevant going rate. For Certificates of Sponsorship assigned from 22 July 2025, the standard general threshold is £41,700, although lower thresholds and alternative salary options can apply where the worker and role satisfy the relevant provisions, including transitional arrangements.

It is therefore unsafe to assume that a single headline salary threshold applies to every sponsored worker.

The employer may need to consider:

• the worker’s basic gross pay
• contracted weekly hours
• the going rate for the occupation
• whether the worker qualifies for any permitted salary provision
• which elements of remuneration can be counted
• whether changes to hours affect the calculation
• whether the proposed salary is consistent with the role being sponsored

If the recruitment budget cannot satisfy the immigration requirements, the employer may need to reconsider the role, remuneration or immigration strategy before proceeding.

7. Check the employer’s ability to sponsor

Where sponsorship is required, the employer needs the appropriate sponsor licence before it can sponsor the worker.

An organisation without the required licence may therefore need to apply to the Home Office before the worker sponsorship process can proceed.

An existing sponsor should check that:

• its sponsor licence remains valid
• the relevant sponsorship route is covered
• its licence status allows sponsorship
• the required Certificate of Sponsorship is available or can be obtained
• its sponsor records are up to date
• there are no outstanding compliance issues capable of affecting the proposed sponsorship

The existence of a sponsor licence should not be treated as the end of the employer assessment.

The organisation still has to determine whether the individual role and worker can properly be sponsored.

8. Plan the recruitment timetable

Immigration can materially affect the date on which an international recruit can start work.

Depending on the circumstances, the process may involve:

Role assessment -> sponsor licence application -> CoS availability -> CoS assignment -> visa application -> biometrics or identity verification -> Home Office decision -> right to work check -> start of employment

Not every case requires every stage, but employers should identify the applicable process before committing to a start date.

Potential causes of delay include:

• needing to obtain a sponsor licence
• waiting for a Certificate of Sponsorship
• obtaining supporting evidence
• visa processing times
• requests for further information
• availability of priority processing
• overseas notice periods
• travel arrangements
• immigration complications arising during the application

Where the recruit is commercially important, immigration planning should form part of the recruitment timetable from the outset.

9. Make the employment offer immigration-aware

An employment offer to a worker who requires immigration permission should reflect the fact that employment may depend on the individual obtaining and maintaining the necessary right to work.

Employers should coordinate the immigration and employment documentation carefully.

Potential issues include:

• whether the offer is conditional on immigration permission
• the proposed employment start date
• salary and working hours
• job title and duties
• work location
• responsibility for immigration costs
• repayment arrangements where legally permissible
• what happens if the visa is refused
• what happens if immigration permission is delayed
• the effect of future loss of permission to work

The information contained in the employment documents should also be consistent with the immigration application and, where applicable, the Certificate of Sponsorship.

Inconsistencies can create avoidable questions about the genuineness or accuracy of the proposed employment.

10. International recruitment as an employer process

Businesses recruiting internationally on a regular basis benefit from treating immigration as an established part of their recruitment process rather than handling each case independently.

A structured process can define:

• when immigration status is assessed
• who determines whether sponsorship is required
• who approves sponsorship costs
• how occupation codes and salaries are checked
• who assigns Certificates of Sponsorship
• how immigration applications are coordinated
• when right to work checks are completed
• how visa expiry dates are monitored
• how changes affecting sponsored workers are reported

This is particularly important where recruitment responsibilities are distributed between HR, talent acquisition, line managers and sponsor licence key personnel.

A clear process reduces the risk that commercial recruitment decisions are made without understanding their immigration consequences.

For the employer, successful international recruitment is therefore not simply about obtaining a visa. It involves aligning the candidate, role, immigration route, sponsorship position, employment terms and compliance requirements before the worker starts employment.
