Immigration Rules for Overstayers in the UK

28.07.2026

Key takeaways

You become an overstayer on the first day after your permission expires. There is no grace period during which you remain lawfully present.
A period of overstaying may be disregarded if you apply within 14 days of your permission expiring and can evidence a good reason beyond your control. This exception now sits at SUI 13.1 of Part Suitability, which replaced paragraph 39E on 11 November 2025.
If you overstay by 30 days or less and leave the UK voluntarily at your own expense, that overstaying is not treated as a breach of immigration laws for future applications, provided it began on or after 6 April 2017.
Beyond 30 days, mandatory refusal periods of 12 months, 2 years, 5 years or 10 years apply, depending on how and when you left the UK.
Overstaying breaks continuous lawful residence for the 10-year settlement route, and those days cannot be recovered even if the overstaying is later disregarded.
Knowingly overstaying is a criminal offence under section 24 of the Immigration Act 1971, carrying a maximum of four years’ imprisonment since the Nationality and Borders Act 2022, although prosecutions for simple overstaying remain uncommon.

This guide explains what happens if you remain in the UK after your immigration permission ends. It covers when overstaying begins, the limited exceptions that allow a late application, the length of re-entry bans, and the practical consequences for work, housing, healthcare and future settlement.

The rules changed significantly on 11 November 2025, when the Home Office replaced Part 9 of the Immigration Rules with the new Part Suitability. The overstaying exceptions that practitioners knew as paragraph 39E are now found at SUI 13.1.

What Is “Overstaying” and When Does It Begin?

You become an overstayer on the first day after your period of immigration permission ends, if you have not secured fresh permission to remain. Even one extra day in the UK without valid leave is a breach of the Immigration Rules.

Many people discover they have overstayed only when they try to open a bank account, renew a driving licence, or leave the country. The Home Office does not send reminders, so responsibility for monitoring the expiry date rests with the individual.

To check whether your permission is still valid, sign in to your UKVI account and view your eVisa. Physical biometric residence permits are no longer issued and most expired on 31 December 2024; the card’s expiry did not end the underlying permission, but the way you prove that permission changed. If you are uncertain, generate a share code through the View and Prove service, or ask a solicitor to confirm your status with the Home Office.

One important exception applies. If you made a valid application before your permission expired and it has not yet been decided, your permission continues automatically under section 3C of the Immigration Act 1971 while that application, and any in-time appeal or administrative review, remains outstanding. You are not an overstayer during that time.

How Long Can You Stay in the UK After Your Visa Expires?

Legally, no days at all. Your right to be in the UK ends on the expiry date shown on your permission, and you are an overstayer from the following day.

Two things are often confused with a lawful grace period, and neither is one:

The 14-day exception (SUI 13.1). This allows a late application to be considered despite the overstaying. It does not make you lawfully present. You remain an overstayer from the day your permission expired and throughout the time your application is pending, with no right to work, rent privately, or claim benefits.
The 30-day departure window. Leaving voluntarily at your own expense within 30 days means the overstaying is not counted as a breach of immigration laws in future applications. It does not make the time you spent in the UK lawful.

The distinction matters because those days still count as unlawful residence for settlement purposes, even where the Home Office disregards them when deciding a particular application.

Frequent Reasons for Overstaying Your UK Visa

Lawful status can end in several ways, and not all of them are obvious to the person affected:

Natural expiry – your eVisa record, entry vignette or older biometric residence permit reaches the date recorded on it.
Curtailment – the Home Office shortens your permission, for example after a relationship breakdown or the revocation of a sponsor’s licence, and serves a notice specifying a new, earlier expiry date.
Conclusion of a pending remedy – where your permission was extended under section 3C during an appeal or administrative review, it ends the moment that process concludes, is withdrawn, or lapses.
Cancellation – permission can be cancelled where the Home Office finds a breach of its conditions, such as working when not permitted.

Informal grace periods sometimes described by applicants have no basis in the current Rules. The 28-day grace period that once existed was abolished on 24 November 2016 and replaced with the narrower 14-day exception.

Is Overstaying Actually a Crime?

Yes. Knowingly remaining in the UK beyond the time limited by your permission is a criminal offence under section 24 of the Immigration Act 1971.

The Nationality and Borders Act 2022 increased the maximum penalty substantially. Overstaying became triable either way, with a maximum of four years’ imprisonment on indictment, replacing the previous six-month summary maximum. A fine may also be imposed.

In practice, prosecutions for simple overstaying are uncommon. They are more likely where the overstaying is prolonged, where it is combined with illegal working, or where deception has been used. A person commits the offence throughout the period of overstaying but can be prosecuted only once in respect of the same grant of permission.

The more realistic risk for most overstayers is not prosecution but administrative: refusal of future applications, enforcement action, and removal.

The 14-Day “Good-Reason” Rule

A period of overstaying can be disregarded if you make a valid application within 14 days of your permission expiring and show a good reason beyond your control that prevented an in-time application. This exception is set out at SUI 13.1(a) of Part Suitability.

You must provide the explanation in or with the application, supported by evidence. Home Office caseworkers assess the plausibility of the reason, whether it was genuinely outside your control rather than a difficulty you could have overcome, and the credibility of the evidence.

Examples the Home Office accepts as reasons beyond an applicant’s control include:

Emergency hospital admission, evidenced by an official letter confirming admission and discharge dates and the nature of treatment.
A close family bereavement, evidenced by a death certificate.
An educational institution failing to issue a Confirmation of Acceptance for Studies promptly.

Reasons that do not qualify include forgetting the expiry date, misunderstanding when permission ended, and waiting for documents such as payslips that you could have obtained earlier. The Home Office has confirmed in published guidance that forgetting to apply is not a good reason beyond the applicant’s control.

The exception is not intended to be used repeatedly, and the Court of Appeal has held that it cannot be relied on twice. There is a separate limb at SUI 13.1(b) covering applications made within 14 days of an earlier in-time application being refused or rejected, or within 14 days of section 3C permission ending.

Where an application is made after the 14-day period, a caseworker may still exercise discretion in exceptional or compassionate circumstances, such as a serious illness lasting beyond 14 days. That discretion must be authorised at Higher Executive Officer grade or above and cannot be relied on as a matter of course. If your circumstances fall outside the Rules altogether, an application outside the Immigration Rules may be the appropriate route.

What Changed Under Part Suitability from 11 November 2025?

On 11 November 2025, Part 9 of the Immigration Rules (Grounds for Refusal) was deleted in its entirety and replaced by a new Part Suitability. All suitability-related refusal and cancellation grounds now sit in one place.

For overstayers, the practical changes are these:

The overstaying exceptions formerly at paragraph 39E are now at SUI 13.1. The substance of the 14-day rule is unchanged, but any application, representation or legal submission should cite the current provision.
Previous breaches of immigration laws are dealt with at SUI 11.1 to SUI 11.8, and the mandatory refusal periods (re-entry bans) at SUI 12.1.
Part Suitability does not apply to applications under Appendix EU or Appendix EU (Family Permit), to most of Part 11 (Asylum), or to Appendix Electronic Travel Authorisation. Separate rules govern those routes.

The 30-Day Voluntary-Departure Window and Re-Entry Bans

Leaving the UK voluntarily at your own expense within 30 days of becoming an overstayer means the overstaying is not treated as a breach of immigration laws, so no re-entry ban applies. This applies to overstaying that began on or after 6 April 2017.

Once you go beyond that window, a mandatory refusal period applies. The length depends on how you left and at whose expense.

Refusal period	Circumstances of departure
12 months	Left voluntarily at your own expense
2 years	Left voluntarily at public expense, within 6 months of being given notice of liability for removal (or of appeal rights being exhausted, whichever is later)
5 years	Left voluntarily at public expense, more than 6 months after that notice
5 years	Left or was removed as a condition of a caution
10 years	Deported or removed from the UK at public expense
10 years	Used deception in an application

The period runs from the date you left the UK, except for deception cases, where it runs from the date of the refusal decision.

Where more than one breach applies, the Home Office counts only the breach producing the longest period. Even after a refusal period expires, an application may still be refused if you previously contrived in a significant way to frustrate the Rules, or where aggravating circumstances such as absconding, illegal working or use of multiple identities are present.

Some family and human rights applications are treated differently, because refusing them could breach Article 8 of the European Convention on Human Rights. A human rights claim is assessed on its own terms, but a history of overstaying still weighs against an applicant in the overall balance.

Consequences Once Your Visa Lapses

Overstaying has immediate practical effects that operate independently of any Home Office decision on your immigration status.

Area	What happens once permission ends
Employment	Paid work and self-employment become unlawful. Employers face civil penalties of up to £45,000 per illegal worker for a first breach in three years and up to £60,000 for a repeat breach, and may lose their sponsor licence
Housing	Landlords must check immigration status. New tenancies are effectively unavailable and existing ones can be ended
Banking	Banks and building societies carry out periodic Home Office checks and must act on accounts held by disqualified persons
Healthcare	Emergency and maternity treatment cannot be refused, but the NHS will invoice for non-urgent care. Outstanding debt of £500 or more for charges incurred after 6 April 2016 can lead to refusal of future applications
Driving	The DVLA can revoke a licence once notified by the Home Office
Benefits	No entitlement to Universal Credit, social housing or most other public funds

These regimes operate in parallel and at different speeds. Not being detected by one authority today is no indication that another will not act tomorrow.

How Does the Home Office Know You Have Overstayed?

The Home Office identifies overstayers primarily through data, not through street-level enforcement. Your permission has a recorded expiry date, and departures are recorded through exit checks, so an absence of any record of departure or of a further grant is visible on Home Office systems.

Several other routes commonly bring an overstay to light:

Right to work and right to rent checks, where an employer or landlord uses the online checking service and the status does not verify.
Data sharing with HM Revenue and Customs, the Department for Work and Pensions, the DVLA, banks and NHS trusts.
A subsequent immigration application, where the immigration history is examined in full.
Contact with the police or another public authority for an unrelated reason.

Because these checks are routine and automated, an unresolved overstay tends to surface at the least convenient moment, often when a person applies for the very status they need.

Long-Term Immigration Impact: ILR and Citizenship

A period of overstaying breaks continuous lawful residence for the 10-year route to indefinite leave to remain under Appendix Long Residence. The lost days cannot be recovered, even where the overstaying was disregarded for the purposes of a particular application.

Disregarding overstaying under SUI 13.1 allows an application to succeed despite the breach. It does not convert unlawful days into lawful residence.

For settlement as a spouse or partner, the position is more flexible, because the family routes do not require ten years of lawful residence in the same way. Discretion is possible, but it is not automatic, and strong compliance after the event matters.

Naturalisation as a British citizen requires the applicant to have been free from immigration time restrictions and to satisfy the good character requirement, which takes immigration breaches into account. A historic overstay frequently means waiting longer before an application is likely to succeed.

Can You Regularise Your Status After Overstaying for 10, 14 or 20 Years?

There is no longer a 14-year route to settlement. The 14-year long residence rule was abolished on 9 July 2012 and replaced by a 20-year route based on private life, now contained in Appendix Private Life.

The distinction between the routes matters:

Appendix Long Residence (10 years). Requires ten years of continuous lawful residence. Overstaying breaks it.
Appendix Private Life (20 years). Requires more than 20 years of continuous residence in the UK, which may be lawful, unlawful, or a mixture of both. This is the route most relevant to long-term overstayers.

Two points are commonly misunderstood about the 20-year route. First, continuity can be broken by absence: more than six months outside the UK at any one time, or 550 days in total across the period relied on, will normally break it, as will removal or deportation. Second, a successful application does not usually produce immediate settlement. An adult is normally granted limited permission of 30 months, and must then complete a further qualifying period on that route before applying for indefinite leave to remain.

Evidence is the practical obstacle. An applicant must document their presence in the UK across the whole period, year by year, which is demanding for anyone who has lived without status and therefore without the usual paper trail.

There is no general amnesty for overstayers in the UK, and none has been announced. Claims to the contrary circulating online are not supported by the Immigration Rules.

Immediate Steps if You Have Already Overstayed

The options available to you narrow quickly with time, so the sequence in which you act matters.

Establish the exact date your permission ended. Check your eVisa record and any curtailment or cancellation notice, and confirm whether section 3C applied at any point. Everything else depends on this date.
Seek legal advice immediately, particularly if you are still inside the 14-day window, where the deadline is strict.
Collect evidence of the circumstances — hospital letters, death certificates, correspondence from a sponsor or institution, records of service outages — while it is still obtainable.
Decide on a strategy. An in-country application, voluntary departure within the 30-day window, or an application from abroad each carry different consequences for future applications.
Avoid further breaches. Illegal working, unpaid NHS charges and failure to report compound the problem and are treated as aggravating factors later.
Keep records of every Home Office letter, submission and receipt, so that your conduct after the breach can be demonstrated.

If you are outside the 14-day window and cannot leave, asylum or a human rights claim may be available depending on your circumstances, and should be assessed properly rather than attempted speculatively.

What Happens Next

Overstaying is rarely resolved by waiting. The consequences accumulate: enforcement regimes operate in parallel, refusal periods lengthen with the manner of departure, and unlawful days permanently affect the settlement clock.

The position is not always as bad as it first appears. Short overstays with a documented reason can be disregarded. Departure within 30 days at your own expense avoids a re-entry ban entirely. Family and human rights routes remain available in cases where the private and family life consequences of refusal are serious. What these outcomes have in common is that they depend on acting quickly and on evidence gathered at the time.

Frequently Asked Questions

How long can I stay in the UK after my visa expires?

Legally, no days at all: you become an overstayer the day after your permission ends. The 14-day exception allows a late application to be considered, but you remain an overstayer throughout that period.

I overstayed my visa in the UK, can I return?

Usually yes, but the timing determines when. If you left voluntarily at your own expense within 30 days of becoming an overstayer, no re-entry ban applies and you can apply again immediately. Beyond 30 days, a refusal period of 12 months to 10 years applies depending on how you left.

Is overstaying a visa a crime in the UK?

Yes. Knowingly overstaying is an offence under section 24 of the Immigration Act 1971, with a maximum of four years’ imprisonment following the Nationality and Borders Act 2022. Prosecutions for simple overstaying are uncommon in practice.

What are valid reasons for overstaying a UK visa?

The Home Office accepts reasons genuinely beyond your control, supported by evidence, such as emergency hospital admission, a close family bereavement, or an institution’s delay in issuing a Confirmation of Acceptance for Studies. Forgetting the expiry date or misunderstanding your visa dates does not qualify.

Can an overstayer apply for asylum in the UK?

Yes. A protection claim can be made at any time regardless of immigration status, and overstaying does not prevent an asylum application from being considered.

Can an overstayer apply for a work visa in the UK?

Not from within the UK in most cases. Switching into a work route generally requires valid permission at the date of application, so an overstayer usually has to leave and apply for entry clearance from abroad, subject to any applicable refusal period.

What happens if my spouse visa expires in the UK?

You become an overstayer the following day and lose the right to work and rent. If you apply within 14 days with a good reason beyond your control, the overstaying can be disregarded for that application, and family route applications are assessed with reference to your private and family life.

Does the 14-day rule make me lawfully present?

No. It allows a late application to be considered despite the overstaying, but you remain an overstayer while the application is pending, without permission to work, rent privately or access public funds.

Is there an amnesty for overstayers in the UK?

No. There is no general amnesty for overstayers and none has been announced. Long-term overstayers may in some cases qualify under the 20-year private life route, which is an established part of the Immigration Rules rather than a concession.

How does overstaying affect indefinite leave to remain?

Overstaying breaks continuous lawful residence for the 10-year settlement route, and those days cannot be recovered even if the overstaying is disregarded for a particular application. Family routes allow more flexibility but not as of right.
