Section 3C of the Immigration Act 1971 keeps your permission alive while an in-time application is decided. It is automatic, it carries your existing conditions unchanged, and it ends the moment you leave the UK. Understanding those three features is what stops people losing status without noticing.
Section 3C
Section 3C Leave and How It Protects Your Status
What Section 3C Leave Is
It is the statutory continuation of permission you already hold. Where you apply to vary your leave before it expires, and it expires before the application is decided, section 3C extends it automatically. There is nothing to apply for and nothing to pay.
Three conditions must all be met: you held limited leave, you applied to vary it before that leave expired, and it expired before a decision was made. The extension continues while the application is neither decided nor withdrawn, and while an appeal or administrative review could still be brought or is pending. It lapses if you leave the UK.
Why It Exists
Because decisions take longer than permissions last. Without it, anyone whose extension application sat in a queue past their expiry date would become an overstayer through no fault of their own — unable to work, rent or drive, and accruing a breach that carries a re-entry ban. Section 3C removes that consequence.
What the Statute Actually Says
- You had limited leave: to enter or remain in the UK.
- You applied to vary it: to the Secretary of State.
- The application was made before the leave expired: the "in-time" requirement.
- The leave expired undecided: the application had not been determined.
All four have to be true. An application made a day late does not attract the protection at all, however good the reason — the fourteen-day exception in the suitability rules protects the application from being treated as out of time, but it does not create section 3C leave.
One Application at a Time
The Act provides that a person may not make an application to vary their leave while it is extended under section 3C. You can vary the application you already have, but you cannot start a second one alongside it. Submitting another application is a frequent and damaging error.
Proving You Have It
This is the practical difficulty. Section 3C leave has no expiry date to point at and no document of its own. Your UKVI account shows the status you held; the evidence that an application is pending comes from the submission confirmation and the payment receipt.
- The submission confirmation: with the application reference and date.
- The payment receipt: for the fee and any health surcharge.
- Your previous grant notice: showing the conditions that continue.
- A share code: generated through your UKVI account, valid for 90 days.
- The biometrics appointment confirmation: or the app upload confirmation.
Our page on the eVisa and share codes covers how the digital record works, and the GOV UK view and prove service is where the codes are generated.
Working Under Section 3C
Your existing conditions continue unchanged. If your permission allowed you to work, it still does; if it restricted your hours, the restriction still applies. Section 3C does not upgrade your rights and it does not remove them.
Employers can verify a continuing right to work using the Home Office employer checking service, which is the route where a share code alone does not resolve the position. Keeping your employer informed early is worth more than any document — see our pages on the Skilled Worker route and the student route for the conditions that carry over.
Applying to switch does not give you the rights of the route you have applied for. Someone on a student visa applying for Skilled Worker keeps student work conditions until the new permission is granted. Starting full-time work on the strength of a pending application is a breach of conditions, and section 3C leave can be cancelled for exactly that.
What the Employer Checking Service Does
Where an online check cannot confirm the position, an employer or landlord asks the Home Office directly and receives a positive verification notice if you have a continuing right. That notice is what gives them a statutory excuse against a civil penalty, and it is generally valid for a defined period, after which the check is repeated.
The practical consequence is that an employer needs your consent and your application reference to make the request. Providing both promptly, in writing, is the difference between a check that takes days and a job offer that quietly evaporates while the paperwork is chased.
Renting Under Section 3C
Landlords in England must check a prospective tenant's right to rent, and a section 3C position is not visible from a document with a date on it. The check is done through the landlord checking service, which is designed for precisely this situation.
Tell a prospective landlord early, and offer the reference number of the pending application. Letting agents unfamiliar with section 3C frequently refuse tenancies they could lawfully grant, and the fix is information rather than argument.
Withdrawal Ends It Immediately
The extension runs while the application is neither decided nor withdrawn. Withdrawing therefore ends your permission on the spot, not at some later date, and there is no grace period afterwards. Anyone considering withdrawing to make a better application should understand that they will be without status from that moment.
Section 3C and Section 3D
Section 3C covers applications to vary leave. Section 3D was the parallel provision covering leave that had been curtailed or revoked, extending it while an appeal was possible or pending. In practice section 3C is the one that matters for almost every applicant, and Home Office guidance treats the two together.
The Conditions That Continue
- Work permissions and restrictions: including hours limits and prohibited employment.
- Study conditions: as they applied to your existing permission.
- The public funds condition: if you had no recourse, you still have none.
- Police registration: where it applied to your grant.
- Any sponsor-linked conditions: tied to the permission you held.
The statute also allows extended leave to be cancelled where the person has failed to comply with a condition attached to the leave, or has used deception in seeking leave to remain. Those are not theoretical: breaching conditions while on section 3C removes the protection as well as creating the breach.
Why You Cannot Travel
The Act is unambiguous: extended leave lapses if the applicant leaves the United Kingdom. Not suspended, not paused — lapsed. You cannot re-enter on it, and the pending application is generally treated as withdrawn.
- The leave: which does not revive on return.
- The application: generally treated as withdrawn.
- The fee: not refunded, though the health surcharge is.
- The qualifying period: a resulting gap can break continuous residence.
- The route back: a fresh entry clearance application from abroad.
This catches people out for funerals, weddings and emergencies. Where travel is unavoidable, take advice before booking rather than after landing — see our page on the continuous residence requirement for what a gap does to a settlement route.
Driving, Banking and Everything Else
Section 3C preserves lawful status, so it preserves the things that depend on it — but those services have their own verification processes, and few of them are designed around a status with no end date. Banks, the DVLA and the NHS all check immigration status in different ways and at different intervals.
Where a service refuses, the answer is usually the same: the verification services exist precisely for this, and the organisation needs to use them. Keep the submission confirmation, the payment receipt and a current share code together so the evidence can be produced without delay each time it is asked for.
When It Ends
- The application is decided: granted or refused.
- The application is withdrawn: by you or by operation of law.
- You leave the UK: immediately, and permanently.
- The time for an appeal or review expires: without one being brought.
- An appeal or review is finally determined: and no further step is available.
- It is cancelled: for breach of conditions or deception.
Where the application is refused and no in-time challenge is made, section 3C ends and you are then without permission. Overstaying from that point carries the consequences on our pages on re-entry bans and refusal grounds.
Appeals and Administrative Review
The statute extends the protection beyond the decision itself. Leave continues while an appeal under section 82 of the Nationality, Immigration and Asylum Act 2002 could be brought or is pending, and while an administrative review could be sought or is pending.
That is frequently the decisive reason to use a formal remedy rather than leaving and reapplying, even where the prospects are modest — the alternative is losing status immediately. See our pages on administrative review and judicial review, noting that judicial review does not sit in the statutory list and does not preserve status that has already ended.
Timing matters more here than anywhere. The extension covers the period while a challenge could be brought, so allowing that window to close ends the protection even if you later decide to act. Our pages on extension processing times and settlement cover what to expect while waiting.

Frequently Asked
Section 3C Questions
Do I have to apply for section 3C leave?
No. It operates automatically where you applied to vary your leave before it expired and the leave expired before a decision was made.
Does it apply if I applied a day late?
No. The application must be made before the leave expires. The fourteen-day rule in the suitability provisions protects the application, but it does not create section 3C leave.
Can I work under section 3C?
On the same conditions as your previous permission. It does not give you the rights of the route you have applied for, only the ones you already had.
Can I travel?
No. Extended leave lapses if you leave the UK, and the pending application is generally treated as withdrawn. It does not revive on return.
How do I prove it to an employer or landlord?
Through the Home Office checking services, supported by your submission confirmation, payment receipt and a share code from your UKVI account.
Can I make a second application while on section 3C?
No. The Act prevents making an application to vary leave while it is extended. You can vary the application you already have.
Does it continue during an appeal?
Yes, while an appeal could be brought or is pending, and while administrative review could be sought or is pending. Judicial review is not in that list.
Can section 3C leave be cancelled?
Yes, where the person has failed to comply with a condition attached to the leave, or has used deception in seeking leave to remain.
Does time on section 3C count towards settlement?
It is lawful leave, so it does not create a gap. Whether a particular period counts towards a qualifying period depends on the route — check the appendix that governs yours.
My employer says they cannot verify my status. What now?
Ask them to use the Home Office employer checking service. Give them your written consent and the application reference — the service exists for exactly this position.
Can I switch route while on section 3C?
Not by starting a new application, which the Act prevents. You may be able to vary the application you already have, which is a different mechanism and worth advice.
What happens when my application is refused?
Section 3C continues while an in-time appeal or review is available or pending. Once that window closes without a challenge, it ends and you are without permission.
