Section 3C leave automatically extends your existing visa and its conditions while the Home Office processes your application. It applies when you apply for further leave before your current visa expires. During Section 3C leave, you can continue to live and work in the UK on the same conditions as your original visa. Leaving the UK ends it immediately.

Section 3C leave is one of the most misunderstood parts of the UK immigration system. Many people do not know it exists — and others misunderstand what it covers.
If your ILR application is pending and you are on Section 3C leave, do not travel internationally. See the ILR processing time guide for current decision timelines.
What Is Section 3C Leave?
Section 3C of the Immigration Act 1971 provides that when a person applies for further leave in time (before their current leave expires), their existing leave is automatically extended by law until the application is decided.
It is called "3C leave" because it comes from Section 3C of the Act.
You do not apply for Section 3C leave. It applies automatically when:
- You have existing leave that has not yet expired
- You apply for further leave before that expiry
- The Home Office has not yet made a decision
What Rights Do You Have on Section 3C Leave?
Section 3C leave preserves the conditions of your original visa — nothing more, nothing less.
If your original visa allowed work: You can continue working for the same employer in the same role on Section 3C leave.
If your original visa had work restrictions: Those restrictions continue during 3C leave.
Right to remain: You are lawfully in the UK during the 3C period. You are not an overstayer.
Access to services: Any services you could access under your original visa — NHS, banking, renting — remain accessible on the same basis.
What 3C leave does NOT give you: No new permissions. No travel rights. No change to your conditions. It simply extends what you already had.
Does Section 3C Leave Cover Administrative Review?
Yes. If your application is refused and you request administrative review, Section 3C leave continues:
- During the 28-day window to request administrative review (whether or not you apply)
- While the administrative review application is pending and being decided
Once the administrative review is decided (or no review is requested within 28 days), Section 3C leave ends.
This means you have time to assess the refusal and request a review without immediately losing your right to remain.
What Ends Section 3C Leave?
Section 3C leave ends when any of the following happens:
- The Home Office makes a decision on your application — whether grant or refusal
- You withdraw your application — 3C leave ends on withdrawal
- You leave the UK — travelling outside the UK, even for one day, ends Section 3C leave
The third point is critical. Do not travel internationally while on Section 3C leave. If you do, you cannot re-enter on the basis of 3C leave. Your application continues — but the leave that permitted your return has ended.
Section 3C Leave and ILR Applications
If you have applied for ILR and your visa expired while the application is pending, you are on Section 3C leave.
Your rights during this period:
- Continue working for your sponsoring employer on the same conditions
- Remain in the UK lawfully
- Use NHS services as before
Your restrictions:
- Do not travel internationally
- Do not change employer or role beyond what your original visa permitted
If your ILR is granted while on 3C leave, you are granted settlement from the date of the decision. The 3C period does not affect your ILR grant.
Common Mistakes
❌ Travelling internationally while on Section 3C leave This ends your 3C leave immediately. You are then attempting to return without valid leave — which can result in refusal at the UK border. If your ILR is still being decided and you leave, the application continues but you may be unable to return. Do not travel.
❌ Not knowing you are on Section 3C leave Some people do not realise their original leave has expired and that they are now on 3C. Check the expiry date on your visa. If your visa has expired and an application is pending, you are on 3C leave.
❌ Assuming 3C leave gives you new rights Section 3C leave extends your existing conditions only. If you were not permitted to do something on your original visa, you are not permitted to do it on 3C leave. It is an extension of what existed — not an upgrade.
❌ Thinking 3C leave ends as soon as the decision is refused If refused, 3C leave continues during the 28-day administrative review window. You have time to assess your options. But once that window closes without a review request, 3C leave ends.
❌ Believing 3C leave is documented in your passport There is no stamp, sticker, or visa label for 3C leave. It exists as a legal provision. If you need to evidence your lawful status (for example, to an employer), you can show your pending application acknowledgement alongside your expired visa.
Expert Tips
1. Set a calendar reminder for your visa expiry date well in advance. If you know your qualifying date is approaching, apply for ILR before your visa expires to ensure 3C leave activates. Missing the deadline means you are out of status — 3C does not apply if you apply after expiry.
2. Keep your Home Office application acknowledgement email. This is your evidence that you applied in time and that Section 3C leave applies. Show it alongside your expired visa if an employer or landlord asks for proof of status.
3. Generate a share code from your UKVI account to prove your right to work. Even on Section 3C leave, your eVisa should reflect that your application is pending. Use a share code for any right-to-work checks rather than showing an expired physical document.
4. Do not risk international travel unless you have a valid visa. If you have a current valid visa (not expired) and your application is also pending, you can travel and return on your existing visa. But if your visa has expired and you are solely on 3C leave, do not travel.
Frequently Asked Questions
What is Section 3C leave in the UK?
Section 3C leave is a legal provision under the Immigration Act 1971 that automatically extends your existing visa and its conditions while the Home Office processes an application you made before your original leave expired. It is not a separate visa — it is a continuation of your existing leave.
Can you work on Section 3C leave?
Yes — if your original visa allowed you to work. Section 3C leave preserves the conditions of your original visa exactly. If your Skilled Worker visa permitted you to work, you can continue to work for the same employer on the same conditions during 3C leave.
Does leaving the UK end Section 3C leave?
Yes. Travelling outside the UK ends Section 3C leave immediately. You cannot return to the UK on Section 3C leave after leaving. Do not travel internationally while on Section 3C leave unless you have a separate, currently valid visa.
How long does Section 3C leave last?
It lasts until the Home Office makes a decision on your application — or until you withdraw your application or leave the UK. If refused, it also continues during the 28-day administrative review window and while any administrative review is pending.
How do you prove you are on Section 3C leave?
Show your expired visa alongside your Home Office application acknowledgement to confirm you applied in time. For online right-to-work checks, your UKVI account may show your application as pending — generate a share code. If there are difficulties evidencing status, contact UKVI.
