Your Leave to Remain Expires Soon

Your current visa or leave to remain in the UK is about to expire. This page explains what you must do before the expiry date, the concept of section 3C leave, and the consequences of overstaying.

Quick Answer

You must submit a valid application to extend or switch your leave before the expiry date — not on or after it. If you submit a valid in-time application, section 3C of the Immigration Act 1971 automatically extends your existing leave on the same terms while the Home Office considers your application. Overstaying — even by one day — has serious consequences for future applications.

Full Explanation

Leave to remain in the UK is time-limited. When it expires, you become an overstayer unless you have made a valid in-time application or have been granted further leave. The 28-day 'grace period' that existed under older Home Office practice no longer applies to most visa categories — do not rely on it.

Section 3C of the Immigration Act 1971 provides that if you have existing limited leave to remain and you make a further application before that leave expires, your leave is automatically extended on the same conditions while: (a) the application is being decided; (b) any appeal or administrative review is pending; and (c) any further appeal to a court is pending. This is known as '3C leave'. It is not a separate grant of leave — it is an extension by operation of law.

You must ensure your application is valid. A defective or incomplete application (for example, missing documents, incorrect fee, wrong form) will not trigger s.3C leave and you may find yourself without any leave while you re-apply. Always use the current application form and pay the correct Immigration Health Surcharge (IHS) and application fee.

The consequences of overstaying are severe: you become an overstayer, which is an immigration offence; you may be removed; future applications — including for settlement — may be refused on the basis that you have not spent the required time in the UK lawfully; and a period of overstaying of more than 30 days after 24 November 2016 triggers an automatic re-entry ban of 1 year (for overstays of up to 30 days) or longer.

If you are approaching expiry and do not qualify under your current route, take urgent specialist advice. You may be able to switch routes (for example, from a student visa to a skilled worker visa if you have a job offer) provided the switch is permitted by the Immigration Rules and you do so before expiry.

Legal Basis

  • §Immigration Act 1971, s.3C — Automatically extends limited leave to remain while a valid in-time application is pending, preventing an inadvertent overstay during the decision period.
  • §Immigration Rules (as amended) — Sets out the requirements for extending or switching each visa category, including the specified documents and financial requirements.
  • §Immigration Act 1971, s.24 — Creates the criminal offence of remaining beyond the time limited by leave — overstaying.

What To Do

1

Identify the Correct Route and Form

Check the GOV.UK Visa and Immigration service to confirm which application route applies to you — extension of your current route, or switch to a new route. Use the current version of the online application form. Check that you meet all the requirements before submitting, because a valid in-time application protects you even if it is ultimately refused.

2

Gather All Supporting Evidence

Each visa category has a list of specified evidence. Assemble all documents before you start the application — salary slips, bank statements, employer letter, English language certificate, accommodation evidence, and so on. Missing specified evidence can cause refusal and may mean your application is not valid, which would undermine s.3C protection.

3

Submit Before the Expiry Date

Submit the complete application with the correct fee and IHS before midnight on the date your leave expires. Keep a screenshot and email confirmation showing the date and time of submission. This is your evidence that the application was in-time and that s.3C leave applies.

4

Maintain 3C Leave During the Decision Period

While your application is pending, your leave continues on the same conditions as before. You may work if your previous leave allowed it. You must continue to comply with any conditions (reporting requirements, no recourse to public funds). Do not travel outside the Common Travel Area unless you are certain you will be able to re-enter.

Important Deadlines

Submit extension or switching applicationBefore the expiry date of current leave — not on the expiry date

Important Warnings

Do not travel outside the UK on s.3C leave without specific advice. Leaving the UK while your application is pending will generally terminate s.3C leave and you may not be able to re-enter.

The Immigration Health Surcharge must be paid in full as part of the application. Failure to pay the correct IHS is one of the most common reasons applications are rejected as invalid.

If you have no recourse to public funds (NRPF) as a condition of your leave, this will normally continue during 3C leave. Do not claim benefits without specialist advice.
