Have you become an overstayer?
Your visa has been refused while you are still in the UK. This is a precarious situation. Understanding your immigration status from this moment forward is not just important—it is an emergency.
A UK visa refusal from within the country triggers a legal countdown. Your right to remain in the UK is no longer secure, and you may be at immediate risk of becoming an “overstayer.” This is a serious breach of UK immigration law with far-reaching consequences. This guide explains how to determine your status and what you must do to protect your position.

Am I an Overstayer? The Role of Section 3C Leave
Whether you are an overstayer depends on when you applied for your visa and when it was refused. The key legal provision here is Section 3C of the Immigration Act 1971.
Section 3C Leave is a form of statutory protection that automatically extends your existing leave while a new, in-time application is pending with the Home Office.
Here is how it works:
- If you made your application before your previous visa expired: Your leave was automatically extended by Section 3C while you were waiting for a decision.
- When the refusal is issued: Your Section 3C leave continues to protect you for the period during which you can bring an appeal or apply for an administrative review.
- If you challenge the decision in time: Your Section 3C leave continues until that legal challenge is finally determined.
You become an overstayer when your Section 3C protection ends, and you have no other leave to remain.
When Does My Section 3C Leave End?
| Scenario | When You Become an Overstayer |
|---|---|
| You do NOT challenge the refusal | The day after the deadline for your appeal or administrative review passes. |
| You apply for Administrative Review and it is refused | The day you receive the AR refusal notice. |
| You appeal and your appeal is dismissed | Once all appeal rights are exhausted (e.g., the tribunal dismisses your appeal and you have no further right to appeal). |
| You applied after your previous visa expired | You were already an overstayer when you applied. The refusal does not change this. |
The Dangers of Overstaying
Being an overstayer, even for a single day, has severe consequences:
- It is a criminal offence.
- You lose the right to work, rent property, or access the NHS for free.
- You are liable to be detained and removed from the UK.
- You will face a re-entry ban of at least 12 months if you overstay for more than 30 days.
- It will negatively impact all future immigration applications.
What Should I Do Immediately?
- Calculate Your Deadline: Check your refusal letter for the date of decision. Your 14-day deadline to challenge the decision starts from this date. This is your window to act to preserve your Section 3C leave.
- Get a Legal Assessment: You must understand if you have valid grounds to challenge the refusal. An immigration lawyer can assess the merits of an appeal or administrative review.
- File an In-Time Challenge: If you have grounds, submitting an appeal or AR application within the 14-day deadline is the only way to extend your Section 3C leave and prevent yourself from becoming an overstayer.
What if I Am Already an Overstayer?
If you have already passed the deadline to challenge the decision, or if you applied out of time, your situation is critical. You should seek legal advice immediately to understand if you have any basis to remain in the UK, such as a strong human rights claim. In most cases, you will be expected to leave the UK voluntarily to mitigate the consequences.
