If you overstay a UK visa by 30 days or less and then leave the UK voluntarily at your own expense, the Home Office does not treat that overstay as a breach of immigration law under the current Immigration Rules. That means no re-entry ban from that overstay alone. Stay longer than 30 days and a ban of 12 months or more can apply. Stay on and apply for another visa late, and you will usually be refused unless you applied within 14 days and had a good reason that was beyond your control.
You will still be asked about your immigration history on future applications, so a short overstay does not simply vanish. These rules apply to people aged 18 or over. Our firm has advised on UK immigration since 2008, and this guide explains how the rules work, where people get caught out and what to do next.
What counts as overstaying a UK visa
You overstay when you remain in the UK after your permission to stay has expired and you have no valid application or appeal pending that keeps your leave alive. Even 1 day counts as overstaying in law. Whether that day matters later depends on how long you stayed, how you left and whether you made a late application.
The most common safety net is section 3C of the Immigration Act 1971. If you apply to extend or switch your visa before it expires, your existing conditions usually continue until you get a decision. Section 3C does not help if you apply after your permission has ended. That is why the expiry date shown in your UKVI account matters more than any date you remember from an old document.
The 30 day rule and the 14 day rule are different things
People often blend these rules into a single grace period. They are not. The 30 day rule deals with leaving the UK after a short overstay. The 14 day rule deals with applying to stay when you are already late.
Rule | What it covers | Conditions | Result |
30 day rule | Leaving the UK after a short overstay | Overstay of 30 days or less that began on or after 6 April 2017, and you left voluntarily at your own expense | The overstay is not treated as a breach, so no re-entry ban follows from it |
14 day rule | Applying to stay in the UK after your permission expired | Application made within 14 days of expiry, with a good reason beyond your control, provided with the application | The overstay is disregarded and the application can be considered |
Both rules sit in the Immigration Rules under Part Suitability. The 30 day figure is much more generous than many older guides suggest. Some still quote a 90 day threshold, but that only applies to overstays that began before 6 April 2017.
Can you apply for another visa after overstaying
If you are still in the UK, you can apply, but an overstay outside the listed exceptions usually leads to refusal. The main exception is an application made within 14 days of your permission expiring with a good reason beyond your control. Applying from abroad is a different test, and a short overstay that fits the 30 day rule should not count as a breach.
The 14 day exception has limits that catch people out. The clock starts on the first day after your permission expires. Making the application does not restore your old permission or conditions. You remain an overstayer until a decision is made, with no right to work, rent privately or claim benefits. A second 14 day window can also apply after an on time application is refused or rejected, which matters if your first application was invalid.
What counts as a good reason
The Home Office looks for a reason beyond your control, or your representative's control. Forgetting to apply, or misreading your expiry date, is not enough on its own. Examples in the Home Office guidance include the following.
- Emergency Hospital Admission
- Close Family Bereavement
- A College Or University Issuing Your CAS Late
Whatever your reason, put the evidence in with the application, such as hospital letters, a death certificate or the emails from your sponsor. Caseworkers can use discretion in exceptional and compassionate cases beyond 14 days, but you should treat that as a rare exception and not as a plan. The Home Office guidance on applications from overstayers sets out how decision makers apply these tests.
What happens if you overstay for more than 30 days
An overstay of more than 30 days is treated as a breach of immigration law, even if you leave on your own. A re-entry ban then runs from the date you leave, and its length depends on how you left. If more than 1 breach applies, only the breach with the longest period counts.
How you left the UK | Re-entry ban from the date you left |
Voluntarily at your own expense | 12 months |
Voluntarily at public expense, within 6 months of being told you were liable for removal | 2 years |
Voluntarily at public expense, more than 6 months after being told | 5 years |
Removed or deported at public expense | 10 years |
Deception in an entry clearance application | 10 years |
During the ban period, an application for entry clearance must be refused unless an exemption applies. Once the period has ended, refusal becomes discretionary. The decision maker has to weigh the circumstances, such as whether you tried to frustrate the rules or whether there were aggravating factors like working in breach of your conditions. The Home Office sets out these tests in its guidance on previous breaches of UK immigration law.
A worked example with real dates
Imagine your Skilled Worker permission ends on 3 March. You book your own flight and leave on 15 March. That is a 12 day overstay, you left voluntarily at your own expense, and the 30 day rule applies. Now imagine you leave on 12 April instead. That is a 40 day overstay, so a 12 month re-entry ban runs from 12 April. Nothing about the person or the visa changed, only the timing.
The rules do not give a worked method for counting the 30 days, so do not plan around the final day. If you are close to the limit, leave earlier than you think you need to and keep your booking confirmation and boarding pass as proof.
Other consequences while you are an overstayer
The re-entry ban is only part of the picture. While you remain in the UK without permission, you face practical and legal problems that grow with every week.
- Loss Of The Right To Work
- Difficulty Renting A Home Privately
- No Access To Most Public Funds
- Risk Of Detention And Removal
- A Possible Criminal Offence
On the last point, section 24 of the Immigration Act 1971 makes it an offence to knowingly remain beyond the time limited by your leave. In practice, most overstayers face immigration action rather than prosecution, but the offence exists and you should not assume it will be ignored.
How a past overstay affects future applications
Application forms ask about your immigration history, and you should answer fully and truthfully. Hiding an overstay is usually worse than the overstay itself. Deception can lead to a 10 year ban on entry clearance applications, which is far heavier than the 12 months a straightforward overstay would attract.
Other countries ask about UK overstays too, particularly on visitor and student visa forms. A past overstay can also complicate settlement, because applications from overstayers are refused unless an exception applies, and it can raise questions about your continuous residence. If you are building towards settlement, the timing of every extension matters.
Which visa types need the most attention
The overstayer rules cover most routes, including work, study, visitor, long residence, ancestry and family applications. Some groups need to watch their dates more closely than others.
If you came on a UK Standard Visitor visa, your stay is normally limited to 6 months, so a delayed flight or a missed booking can push you over the limit quickly. People on a Temporary Worker visa usually have a fixed end date that does not move, so plan the next step well before it arrives.
Founders and entrepreneurs should apply early for an extension or settlement. That applies to those on an Innovator Founder visa and to those using an entrepreneur visa extension or heading towards Tier 1 Entrepreneur indefinite leave to remain. An on time application keeps your permission alive through section 3C, but a late application does not. The same logic applies to anyone holding a Global Talent visa.
Family and heritage routes have their own timing rules. If you hold a UK Ancestry visa or a BN(O) visa, the route to settlement depends on continuous lawful residence, so an unplanned gap can cost you time. EU citizens who work in the UK but live elsewhere should also check renewal dates on their Frontier Worker permit well in advance.
What to do if your visa has expired or is about to
Check your exact expiry date
Look at the expiry date shown in your UKVI account and compare it with any decision letter. Work out how many days you are over, or how many you have left. The 14 day period starts on the first day after your permission ended, so be careful with your counting.
Decide whether you are leaving or staying
If you plan to leave, do it quickly and at your own expense, ideally well inside the 30 days. If you want to stay, you need a valid application that fits the 14 day rule or another basis for staying, and you should get advice before you submit anything.
Gather your evidence now
Keep travel bookings, medical letters, sponsor emails and anything else that shows why the date was missed. Evidence that is easy to find today can be hard to track down in 3 months.
Take advice before you act
Some overstayers have a genuine basis to stay, such as family life in the UK or long residence, but those are separate applications with their own tests. A regulated solicitor can tell you which of these fits your situation and whether leaving and applying from abroad is the safer path.
Frequently asked questions
How long can you overstay in the UK without getting a ban
If your overstay began on or after 6 April 2017, you can overstay by up to 30 days without a re-entry ban, as long as you leave voluntarily and at your own expense. Anything beyond 30 days is a breach, and a ban of at least 12 months can follow. Do not treat 30 days as a target.
Is overstaying a UK visa a criminal offence
It can be. Knowingly remaining beyond the time your leave allows is an offence under section 24 of the Immigration Act 1971. Most cases are dealt with through immigration action rather than prosecution, but that is not guaranteed.
Can you work if your visa has expired
No. Once your permission has ended you have no right to work, even if you have made a late application under the 14 day rule. Employers who use illegal workers risk civil penalties.
Can you come back to the UK after overstaying
Often yes. If you overstayed by 30 days or less and left voluntarily at your own expense, there is no ban from that overstay. If you overstayed by more, you may have to wait out a ban of 12 months or longer before an application can succeed.
Do you have to declare an overstay on a new application
You should answer every question about your immigration history honestly. Forms ask about previous breaches, and leaving an overstay out can create a separate deception problem that is harder to fix than the overstay itself.
Speak to an immigration solicitor before you book a flight
Timing is the whole game with overstaying. A few days can be harmless, 31 days can start a ban, and a late application with no good reason can end in refusal. If your visa has expired, or you are not sure how many days you have, speak to a regulated immigration solicitor before you do anything else.
