Section A: What is section 3C leave?
Section 3C leave protects a person from becoming an overstayer where their existing UK immigration permission expires while a qualifying application to extend or vary that permission remains outstanding. It operates automatically under section 3C of the Immigration Act 1971. There is no separate application for section 3C leave.
The protection does not arise merely because an application has been submitted to the Home Office. The application has to meet the statutory requirements. In particular, it must have been made before the person’s existing permission expired and must be capable of extending that permission under section 3C.
What does section 3C leave mean?
Section 3C leave is a statutory continuation of a person’s existing limited leave to enter or remain in the UK. Its purpose is to preserve lawful immigration status while the Home Office is deciding an in-time application and, where applicable, while an appeal or administrative review remains pending.
It is not a new grant of immigration permission and does not place the applicant onto the immigration route for which they have applied. Instead, the person remains in the UK under the conditions attached to their previous permission until section 3C leave ends. Those conditions can include restrictions on employment, study and access to public funds.
Who qualifies for section 3C leave?
Under section 3C of the Immigration Act 1971, leave will be extended where:
- the person has limited leave to enter or remain in the UK
- they apply to the Home Office to vary that leave
- the application is made before their existing leave expires
- their existing leave expires before the application is decided
- the application has not been decided or withdrawn
The application must also be valid. Home Office guidance states that an invalid application does not engage section 3C. An application submitted before visa expiry may therefore fail to preserve lawful status if it does not satisfy the applicable validity requirements and is not subsequently validated.
Section 3C does not generally apply to an application made after the person’s immigration permission has expired. A person who submits a late application may have grounds for the period of overstaying to be disregarded under a specific Immigration Rule, but that does not retrospectively create section 3C leave or reinstate the conditions attached to the expired permission.
When does section 3C leave start?
Section 3C leave begins when the person’s existing immigration permission expires, provided a qualifying application remains undecided at that point.
Until the original expiry date, the person continues to hold their existing permission in the usual way. Section 3C only becomes operative where that permission reaches its expiry date before the Home Office has decided the application.
For example, where permission expires on 30 September and a valid extension application is submitted on 25 September, the person remains under their existing permission until 30 September. If the application is still undecided, section 3C leave begins on 1 October.
If the Home Office decides the application before the existing permission expires, section 3C is not engaged. The person’s position will instead depend on the outcome of the application and any new permission granted.
Does section 3C leave arise automatically?
Section 3C leave arises by operation of law once the relevant conditions are met. The Home Office does not issue a separate section 3C visa and the applicant does not receive a new period of permission with its own expiry date.
Automatic operation does not mean the status will always be straightforward to establish. The applicant may still need to prove when the application was made, whether it was valid and what conditions were attached to the previous permission. Home Office records and online status services may not immediately display section 3C leave as a separate status.
Applicants should retain the application submission confirmation, payment records, biometric correspondence and any notice confirming that missing information has been accepted. These documents do not themselves determine whether section 3C applies, but they may be relevant when the applicant or an employer needs to establish the underlying facts.
Invalid applications and section 3C leave
An invalid application does not ordinarily extend leave under section 3C. Common validity issues can include use of the wrong application process, failure to pay the required fee, failure to complete an identity requirement or omission of a mandatory document where the Immigration Rules make that document part of the validity requirements.
Some defects can be corrected where the Home Office gives the applicant an opportunity to provide the missing information or payment. Where an application submitted in time is subsequently validated, Home Office guidance provides that section 3C leave can operate from the date immediately after the previous permission expired.
The position is different where the defect is not corrected or the application remains invalid. In that situation, section 3C will not have extended the person’s leave from the original expiry date. The applicant may therefore have become an overstayer even though they believed an application was pending.
Biometric non-compliance requires particular care. Home Office guidance distinguishes between an application that was invalid from the outset and an application that later becomes invalid because the applicant failed to provide biometrics. In the latter case, section 3C leave may end when the Home Office serves notice that the application is invalid.
Section 3C eligibility examples
| Application position | Section 3C effect |
|---|---|
| A valid application is submitted before existing permission expires and remains undecided on the expiry date. | Section 3C leave normally begins when the existing permission expires. |
| The application is submitted after existing permission has expired. | Section 3C leave does not normally arise. |
| An in-time application is invalid and is not subsequently validated. | The application does not extend leave under section 3C. |
| An in-time defective application is subsequently validated following a Home Office request. | Section 3C may operate from the day after the previous permission expired. |
| The application is decided before the existing permission expires. | Section 3C is not engaged. |
| The applicant withdraws the outstanding application after section 3C has begun. | Section 3C leave ends when the withdrawal takes effect. |
Whether section 3C leave applies can therefore depend on more than the date shown on an application confirmation. The previous immigration status, application date, validity requirements and procedural history all have to be considered together.
The statutory test and invalid-application treatment reflect the current Immigration Act 1971 and Home Office section 3C guidance.
DavidsonMorris Insight
Many people assume that submitting an application before their visa expires automatically protects their immigration status. In practice, section 3C leave depends on whether the application satisfies the statutory requirements, including validity. Where an application later proves to be invalid, the applicant may discover that section 3C leave never arose, creating an unexpected period of overstaying that can affect future applications and settlement.
Section B: Does Section 3C Leave Give You the Right to Work?
A person can continue working during section 3C leave where their previous immigration permission allowed them to work. The permission and restrictions attached to the previous visa continue on the same terms while section 3C applies. Section 3C does not grant a new right to work or remove restrictions imposed under the previous immigration route.
Visa expiry does not therefore mean that employment has to end where the worker made a qualifying in-time application and holds section 3C leave. The employer must still establish that the worker is permitted to undertake the particular work and complete the appropriate right to work check.
Can you work while on section 3C leave?
The right to work during section 3C leave depends on the conditions attached to the person’s previous immigration permission. Where that permission allowed employment, the same permission ordinarily continues. Where work was prohibited or restricted, the prohibition or restriction also continues.
For example, a person whose previous permission allowed unrestricted employment can generally continue working without a new restriction being imposed by section 3C. A person subject to limits on working hours, occupation or employer remains subject to those limits. Someone who did not have permission to work before their leave expired does not acquire a right to work because an application is pending.
Home Office guidance confirms that section 3C extends the existing immigration permission and its associated conditions. Those conditions remain in force unless they are varied by the Home Office or section 3C leave comes to an end.
Working after your visa has expired
A worker may continue working after the expiry date shown on their previous visa where section 3C leave has extended their permission and the previous conditions authorised the work in question. The expired date on an eVisa or earlier immigration document is not, on its own, evidence that the person has lost the right to work.
The position is different where the application was made after the previous permission expired. A late application does not ordinarily engage section 3C and the conditions attached to the previous permission, including any right to work, cease when that permission expires. A rule allowing a period of overstaying to be disregarded for the purpose of deciding an application does not reinstate the person’s former permission to work.
The same risk arises where an application made before expiry is invalid and is not subsequently validated. An applicant should not assume that evidence of submission is sufficient to establish an ongoing right to work.
Work restrictions continue during section 3C leave
Section 3C preserves the conditions of the previous permission rather than the conditions of the immigration route for which the person has applied. A pending application does not place the applicant under the work conditions of the proposed new route.
The continuing conditions may affect:
- which employer the person can work for
- the role or occupation they can undertake
- the number of hours they can work
- whether supplementary or additional employment is permitted
- whether self-employment or business activity is allowed
- whether the person can access public funds
A person applying to switch into a route with broader work permission cannot rely on the conditions of that proposed route before permission is granted. Equally, an applicant moving into a more restrictive route remains subject to their existing conditions while section 3C continues.
Section 3C leave for sponsored workers
A sponsored worker whose permission is extended by section 3C will ordinarily remain subject to the employment conditions attached to their previous sponsored permission. The fact that an extension or change-of-employment application is pending does not create a general right to undertake any sponsored role.
Where the worker is continuing in the same sponsored employment, section 3C may allow that employment to continue after the previous visa expiry date. The employer will still need to comply with its sponsor duties and establish a statutory excuse through the prescribed right to work process.
Greater care is required where the worker proposes to change employer, occupation code, role or other material employment terms. Whether the new work can begin before the application is decided depends on the worker’s existing conditions and the rules applying to the immigration route and proposed change. A Certificate of Sponsorship or pending visa application does not, by itself, establish permission to start the new employment.
Students, dependants and other visa holders
A Student whose leave continues under section 3C remains subject to the work restrictions imposed under their previous Student permission. These may include limits on term-time hours and prohibitions on particular types of work. Applying under a route that would permit unrestricted employment does not remove those restrictions while the application remains pending.
A dependant who previously held permission allowing employment will generally retain the same work conditions during section 3C leave. Any restriction attached to the dependant permission also continues.
The same principle applies across other immigration categories: the previous conditions remain determinative until the Home Office grants new permission, varies the conditions or section 3C leave ends.
Can you start a new job during section 3C leave?
Section 3C does not impose a universal prohibition on changing jobs, but neither does it provide general permission to begin new employment. The answer depends on whether the proposed work is allowed under the conditions of the person’s previous permission and any route-specific provisions that apply to the pending application.
A person with unrestricted work permission may be able to change employer while section 3C continues. A worker whose permission is tied to a particular sponsor or employment may not be able to begin the new role merely because an application to change employment has been submitted.
Both parties should confirm the applicable work conditions before the new employment starts. An employer that relies only on an application receipt, Certificate of Sponsorship or expired visa record may not establish a statutory excuse against an illegal working civil penalty.
Having a right to work and proving it are different issues
A worker may hold section 3C leave as a matter of law even where their online immigration record does not clearly display that status. The Home Office has confirmed that section 3C leave may be inferred from application, appeal and administrative review records rather than recorded as a separate formal application outcome.
The existence of section 3C leave determines whether the person remains lawfully present and subject to their previous work conditions. The right to work checking regime determines whether the employer has completed the prescribed steps needed to establish a statutory excuse.
An employer should not assume that the right to work has ended because the previous visa date has passed. Nor should it continue employment solely because the worker says that an application is pending. Where the right to work cannot be confirmed through the usual online service, the employer may need to use the Employer Checking Service.
The verification process, the temporary protection available to an existing employer and the effect of a Positive Verification Notice are considered in the next section.
DavidsonMorris Insight
The most common misunderstanding is that section 3C creates a new right to work. It does not. It preserves the work permission attached to the previous immigration status. Before changing employer, accepting a promotion or increasing working hours, check that the proposed work remains permitted under the existing conditions rather than the immigration route you have applied for.
Section C: How Employers Check Section 3C Right to Work
An employee may continue to have the right to work after the expiry date of their previous immigration permission, but the employer must still complete the prescribed verification process. The existence of section 3C leave and the employer’s statutory excuse are related but separate legal questions.
Section 3C determines whether the employee’s previous immigration permission and work conditions continue. A compliant right to work check protects the employer against civil penalty liability if the employee is later found to have been working illegally.
How can an employee prove section 3C leave?
An employee relying on section 3C leave should tell their employer that they made an application before their previous permission expired and provide the information needed for a follow-up right to work check.
Depending on the person’s immigration record, they may be able to generate a share code so that the employer can use the Home Office online right to work service. The online service now supports a range of eVisa holders with outstanding in-time applications. Where the check confirms continued permission to work, it will also state any applicable restrictions and the date on which the employer must conduct another check.
Where the employee cannot generate a usable share code or the online service does not confirm the position, the employer may need to use the Employer Checking Service. Application receipts, Home Office acknowledgement emails and solicitor correspondence can help explain why the employee claims to have continuing permission, but they do not by themselves give the employer a statutory excuse.
Online right to work checks
An online check should be used where the employee can provide a valid right to work share code. The employer must access the employer-facing Home Office service rather than relying on a screenshot or information displayed by the employee on their own account.
The employer should confirm that:
- the photograph on the online profile is of the person presenting for work
- the service confirms that the person has the right to undertake the work in question
- any restrictions on occupation, employer, hours or type of work are observed
- the profile is retained electronically or in hard copy for the duration of employment and for two years afterwards
- any required follow-up check is diarised
Where the online service confirms a right to work based on an outstanding in-time application, the statutory excuse will normally last for six months. A further prescribed check is required before that period expires if the application remains outstanding.
When should an employer use the Employer Checking Service?
The Employer Checking Service is used where the right to work cannot be established through the standard online or manual checking process. It is particularly relevant where the individual has an outstanding application, appeal or administrative review with the Home Office and cannot otherwise prove their current status.
An employer should use the service where it is reasonably satisfied that the employee has:
- an outstanding in-time application to extend or vary their permission
- a pending appeal against a Home Office decision
- a pending administrative review
- technical or status-record issues preventing an online check
The service should only be used where the employer cannot complete the appropriate check using a share code or acceptable original documents. The Home Office states that the Employer Checking Service aims to respond to a valid request within five working days.
Where an application, appeal or administrative review has only recently been submitted, Home Office guidance advises employers to wait at least 14 calendar days before requesting verification so that the matter can be registered on Home Office systems.
Positive Verification Notices
A Positive Verification Notice confirms that the Home Office has verified that the named individual is permitted to undertake the work in question. It provides the employer with a time-limited statutory excuse for six months from the date stated in the notice.
The notice should be retained securely for the duration of employment and for two years after employment ends. The employer should also record the date on which the six-month protection expires and complete a further check before that date where the employee’s application or challenge remains unresolved.
A Positive Verification Notice does not remove the conditions attached to the employee’s immigration permission. The employer must still check that the role, hours and other employment arrangements fall within the work permitted by the notice.
If the Employer Checking Service issues a Negative Verification Notice, the employer will not obtain a statutory excuse by continuing to employ the person. The result should be reviewed carefully before action is taken, particularly where the employee disputes the accuracy of the Home Office record.
The 28-day statutory excuse for existing employees
A limited protection may apply where an employer previously completed a compliant right to work check and the employee’s time-limited permission subsequently expires.
Where the employer is reasonably satisfied on the expiry date that the employee has an outstanding application, appeal or administrative review, the existing statutory excuse can continue for up to 28 calendar days. The period allows the employer to obtain a Positive Verification Notice or complete a Home Office online check.
The employer may rely on information such as a Home Office acknowledgement, application reference, tribunal reference or proof of the submission date when deciding whether it is reasonably satisfied that a matter is pending. That evidence does not independently provide a statutory excuse and should not be treated as a substitute for the required follow-up check.
The 28-day period applies only where the employer held a valid statutory excuse from an earlier check. It does not apply to a prospective employee who has not yet started work. In a new recruitment case, employment should not begin until the employer has completed a prescribed check or obtained a Positive Verification Notice.
The protection can also end before the 28 days expire if the Employer Checking Service issues a negative response. An employer that continues employment after receiving confirmation that the person does not have the right to undertake the work will not retain a statutory excuse.
Right to work checks for new employees
A prospective employee may have section 3C leave and an underlying right to work, but the employer must establish that right before employment starts. There is no 28-day grace period for completing the initial check.
Where the applicant can provide a share code, the employer should complete the online check before the start date. Where online verification is unavailable, the employer should obtain a Positive Verification Notice through the Employer Checking Service before allowing the individual to begin work.
A pending application confirmation, expired visa, Certificate of Sponsorship or assurance from the employee’s adviser will not, without the prescribed verification, establish the statutory excuse required for a new employee.
What if the online record is wrong?
Section 3C leave may exist as a matter of law even where the eVisa or online checking service does not accurately reflect the employee’s current position. Home Office guidance acknowledges that section 3C can be inferred from application, appeal and administrative review records rather than recorded as a separate formal status outcome.
The employee can ask the Home Office to correct an inaccurate immigration status record where the error has prevented access to work. The employer should also submit an Employer Checking Service request where the prescribed conditions are met rather than relying solely on the disputed online result.
Can an employer suspend or dismiss an employee?
The expiry of the date shown on an employee’s previous immigration record does not, without more, establish that the right to work has ended. An employer should first determine whether an in-time application was made and use the appropriate Home Office checking process.
Employers should give an existing employee a reasonable opportunity to establish that they continue to have the right to work. Where the employer previously carried out a valid check and is reasonably satisfied that an application or challenge is pending, the 28-day statutory excuse may provide time to obtain formal verification.
Continued employment without a prescribed check can expose the employer to civil penalty and, in cases involving knowledge or reasonable cause to believe that the work is prohibited, criminal liability. Conversely, immediate suspension or dismissal without investigating section 3C status and Home Office verification may create contractual, discrimination and unfair dismissal risks.
The employer should consider the immigration and employment law position together before deciding whether to suspend, withhold pay or terminate employment.
Employer checklist for section 3C cases
- Check the expiry date and work conditions attached to the previous permission.
- Confirm when the outstanding application, appeal or administrative review was submitted.
- Establish whether an earlier compliant right to work check created a statutory excuse.
- Ask the employee for a share code and complete an online check where available.
- Use the Employer Checking Service where the position cannot be verified online or manually.
- Retain the online profile or Positive Verification Notice in the prescribed form.
- Record the expiry of any 28-day or six-month statutory excuse.
- Complete the required follow-up check before the existing protection ends.
Section 3C cases should not be managed solely by reference to the expiry date shown on the previous visa. The employer has to establish whether permission continued, verify the work allowed and retain evidence of the prescribed check.
DavidsonMorris Insight
Many right to work disputes arise because employers and employees are relying on different evidence rather than different legal rules. An employee may genuinely have section 3C leave while the employer still lacks the prescribed statutory excuse. Resolving the issue usually requires the correct Home Office verification process rather than assumptions about whether permission exists.
Section D: When Section 3C Leave Ends
Section 3C leave is temporary. It continues only while the statutory requirements remain satisfied. Once one of the events specified in section 3C occurs, the extended leave ends and the person’s immigration position changes accordingly.
Many applicants assume that section 3C continues until the Home Office makes a final decision on every possible challenge. The position is more nuanced. Whether section 3C continues depends on the stage reached in the immigration process and whether the relevant statutory deadlines have been met.
How long does section 3C leave last?
Section 3C leave normally continues while an in-time application to vary or extend leave remains outstanding and undecided.
Where the application is refused, section 3C may continue during the period allowed for bringing an in-country appeal or applying for administrative review, provided the refusal decision carries those rights. If an appeal or administrative review is lodged within the applicable deadline, section 3C generally continues while that process remains pending.
The continuation of leave depends on the statutory framework applying to the particular refusal. Not every immigration decision attracts a right of appeal or administrative review, and section 3C does not continue indefinitely simply because the applicant wishes to challenge the decision.
When does section 3C leave end?
Section 3C leave will usually end when:
- the Home Office grants the application and new immigration permission begins
- the application is finally refused and no further continuation of leave applies
- the applicant withdraws the outstanding application
- the period for bringing an appeal or administrative review expires without action being taken
- a pending appeal or administrative review is finally determined
- the person leaves the United Kingdom
Once section 3C ends, the continuation of the previous immigration permission also ends. Unless new leave has been granted, the person may become an overstayer from that point.
What happens if the application is granted?
Where the Home Office approves the application, section 3C leave ends immediately before the new immigration permission takes effect. The applicant then becomes subject to the conditions attached to the newly granted visa.
For example, a worker granted permission under a different immigration route becomes subject to the work conditions attached to that new route rather than those preserved under section 3C.
What happens after a refusal?
A refusal does not necessarily bring section 3C leave to an immediate end. The outcome depends on whether the decision carries a right of appeal or administrative review.
Where an in-country appeal right exists, section 3C generally continues throughout the period allowed for bringing the appeal. If the appeal is lodged within that period, leave normally continues until the appeal is finally determined.
A similar approach applies where the decision carries a right to administrative review. Section 3C generally continues during the period allowed for seeking review and, where the application is made in time, while the administrative review remains outstanding.
If the relevant deadline passes without an appeal or administrative review being lodged, section 3C normally ends when that deadline expires.
Does leaving the UK end section 3C leave?
Leaving the United Kingdom automatically brings section 3C leave to an end.
This rule often catches applicants by surprise. A person who travels overseas while relying on section 3C protection cannot ordinarily resume that section 3C leave simply by returning to the UK. The pending immigration application may also be treated as withdrawn under the Immigration Rules, depending on the circumstances and the route involved.
Anyone considering overseas travel while an application remains outstanding should obtain advice before making travel arrangements.
Can you withdraw an application?
An applicant may withdraw an outstanding immigration application, but doing so has important legal consequences.
Where section 3C leave has arisen because of that application, withdrawal normally brings the continuation of leave to an end. Unless another form of immigration permission exists, the individual may become an overstayer from the date the withdrawal takes effect.
Applicants should therefore consider the wider immigration consequences before asking the Home Office to withdraw a pending application.
Can you change your application?
Applicants sometimes decide that they wish to pursue a different immigration route before the Home Office has reached a decision.
Immigration law distinguishes between varying an existing application and making an entirely separate new application. Whether a variation is possible depends on the procedural rules applying at the time. Attempting to submit a fresh application without understanding those rules may affect the operation of section 3C leave.
Where an applicant wishes to change immigration route after submitting an application, advice should usually be obtained before taking further action.
Section 3C leave and continuous residence
Section 3C leave can preserve lawful residence while a qualifying application, appeal or administrative review remains pending. That protection is often important for applicants working towards indefinite leave to remain.
Whether a period of section 3C leave counts towards a particular settlement route depends on the Immigration Rules governing that route. Continuous residence requirements vary between immigration categories, and not every period of lawful residence is treated in the same way for settlement purposes.
Applicants relying on section 3C leave as part of a future settlement application should ensure that there has been no break in lawful status caused by a late application, invalid application or missed appeal deadline.
Common mistakes
Many section 3C problems arise because applicants misunderstand when the statutory protection begins or ends. Common errors include:
- assuming every pending application creates section 3C leave
- travelling outside the UK while relying on section 3C
- withdrawing an application without considering the consequences
- missing an appeal or administrative review deadline
- assuming lawful residence automatically counts towards settlement without checking the relevant Immigration Rules
The end of section 3C leave often determines whether a person remains lawfully present in the UK and whether they continue to have permission to work, so understanding when that protection ends is therefore just as important as understanding when it begins.
DavidsonMorris Insight
The end of section 3C leave is usually the highest risk juncture. Travelling overseas, withdrawing an application or missing an appeal or administrative review deadline can end the statutory protection immediately, even where the individual believed their immigration position remained secure. Those decisions should be made only after considering their wider immigration consequences.
Section E: What to Do if Your Section 3C Leave or Right to Work Is Unclear
Most section 3C cases are straightforward. Difficulties usually arise where there is uncertainty about whether the application was valid, whether section 3C leave has ended or whether the employer can verify the employee’s continuing right to work.
Taking action without establishing the legal position can have significant consequences. An employee may stop working unnecessarily despite continuing to have permission, while an employer may expose itself to civil penalties by relying on assumptions rather than completing the prescribed checks.
What should workers do?
If you believe section 3C leave applies, establish the facts before making decisions about employment, travel or a further immigration application.
You should confirm:
- when your previous immigration permission expired
- when your application was submitted
- whether the application satisfied the Home Office validity requirements
- whether the Home Office has requested further information or biometrics
- whether any appeal or administrative review deadlines apply
- the work conditions attached to your previous immigration permission
You should also keep copies of your application confirmation, payment receipt, biometric correspondence and any Home Office communications. Although these documents do not establish section 3C leave by themselves, they may help demonstrate the chronology where your status is questioned.
If your employer cannot verify your right to work online, tell them that an in-time application has been made and ask them to consider whether an Employer Checking Service request is appropriate.
What should employers do?
Employers should investigate the position before concluding that an employee has lost the right to work because the expiry date shown on their previous visa has passed.
Where an employee says they have made an in-time application, employers should establish the relevant facts and complete the prescribed Home Office verification process.
A practical approach is to:
- confirm the expiry date of the employee’s previous permission
- obtain evidence of when the application, appeal or administrative review was submitted
- complete an online right to work check where a share code is available
- use the Employer Checking Service where the Home Office guidance requires it
- retain the prescribed evidence and record any follow-up check date
Employers should avoid relying solely on application acknowledgements, solicitor letters or assurances from the employee without completing the prescribed verification process. Equally, they should avoid assuming that visa expiry automatically ends the employee’s permission to work.
When should legal advice be sought?
Professional advice should be obtained where the application history or immigration status is uncertain, particularly if there is a risk that section 3C leave may never have arisen or may already have ended.
Advice is commonly needed where:
- there is uncertainty about whether an application was valid
- the application was submitted shortly before or after visa expiry
- the Home Office disputes that section 3C leave applies
- the Employer Checking Service issues a Negative Verification Notice
- an employer is considering suspension or dismissal because of right to work concerns
- the applicant intends to travel while relying on section 3C leave
- an application may need to be varied or withdrawn
- future settlement depends on preserving continuous lawful residence
Early advice can often resolve evidential or procedural issues before they affect employment, sponsorship or future immigration applications.
DavidsonMorris Insight
Section 3C leave frequently becomes important years after the original application, particularly where an employer questions a worker’s status or an applicant later applies for settlement. Keeping clear records of application dates, Home Office correspondence and right to work checks can make the difference between demonstrating continuous lawful residence and facing difficult evidential disputes long after the original application was made.
Summary
Section 3C leave can preserve a person’s lawful immigration status after their existing permission expires, provided they made a valid application before expiry and the application remains outstanding. It does not grant a new immigration status or a wider right to work. Instead, the conditions attached to the previous permission continue, including any limits on employer, role, hours or type of work.
Employers should not treat visa expiry as conclusive evidence that the right to work has ended. They must complete the prescribed right to work process, using the Home Office online service or Employer Checking Service where required, and retain evidence of the resulting statutory excuse.
Application validity, withdrawal, overseas travel and missed appeal or administrative review deadlines can affect whether section 3C leave applies or continues. Where the position is uncertain, workers and employers should establish the legal and evidential position before employment is stopped, an application is changed or the individual leaves the UK.

FAQs
What is section 3C leave?
Section 3C leave is a statutory extension of existing limited leave under the Immigration Act 1971 where a valid in-time application to extend or vary immigration permission remains undecided when the previous permission expires.
Can I work while on section 3C leave?
Usually, yes, if your previous immigration permission allowed you to work. The same work conditions continue during section 3C leave until it ends. Section 3C does not create new work permission or remove existing restrictions.
Does section 3C leave start automatically?
Yes. Where the statutory requirements are met, section 3C leave arises automatically. There is no separate application or grant of section 3C leave.
Can I change jobs during section 3C leave?
That depends on the conditions attached to your previous immigration permission. A pending application does not automatically authorise employment that was not previously permitted.
How can my employer check my right to work?
Your employer may be able to verify your status using the Home Office online right to work service. Where that is not possible, they may need to obtain a Positive Verification Notice through the Employer Checking Service.
Does section 3C leave end if I travel outside the UK?
Yes. Leaving the UK brings section 3C leave to an end. Depending on the immigration route and the Immigration Rules, travelling overseas may also affect your pending application.
Does section 3C leave count towards indefinite leave to remain?
Section 3C leave can preserve lawful residence, but whether the period counts towards settlement depends on the Immigration Rules applying to the particular immigration route.
What happens if my application is invalid?
An invalid application does not ordinarily extend leave under section 3C. If the defect is not corrected in accordance with the Home Office validity process, you may become an overstayer when your previous permission expires.
Can my employer dismiss me because my visa has expired?
Not necessarily. An employer should first establish whether section 3C leave applies and complete the appropriate Home Office right to work checks before making decisions about continued employment.
