Overstaying a Visa: What Happens in Schengen, the UK and the US

An overstay starts the day after your authorized stay ends, which is often long before your visa expires. Here is how each system detects it, what it costs you, and how accidental overstays happen.

Your visa is not your stay limit

A visa is permission to travel and ask for entry. The authorized stay is how long you may remain once admitted, and the two are set separately. A Schengen visa valid for a year still allows only 90 days in any 180. A US visitor visa can be valid for years while each admission is limited to the date on your I-94 record. Staying until the date printed on the visa is one of the most common ways people overstay without meaning to.

The other common causes are just as ordinary:

• Rolling windows. Under a rule like Schengen 90/180, several short trips can breach the limit together, although no single trip looks long.
• Miscounted travel days. Schengen counts the day you enter and the day you leave as full days of stay. Leaving out the arrival day, or counting nights instead of days, puts you a day or two over.
• A shorter grant than expected. The US admission date is set by the CBP officer and shown on your I-94. It can be earlier than you assumed, so check it after every arrival.
• Long-stay visa confusion. Time spent on a national long-stay (D) visa or a residence permit does not count toward the Schengen 90 days, but that status lets you spend only 90 days in any 180 in the other Schengen countries, and it does not stretch past its own end date.

The same trips are legal if the traveler leaves on 17 June. For the full counting method, see the Schengen rolling window walkthrough.

Schengen: every overstay is now recorded

The Entry/Exit System (EES) began its rollout in October 2025 and has been fully operational since 10 April 2026. It replaces passport stamps with a digital record of each entry and exit by non-EU short-stay travelers, including a facial image and fingerprints. The system calculates your remaining authorized stay, and it automatically identifies records with no exit after the stay ended and records where the maximum stay was exceeded. National authorities receive a list of identified overstayers.

EES keeps entry and exit records for 3 years. If there is no exit record after your authorized stay expired, the data is kept for 5 years from that expiry date.

What follows is decided by the country where you are, under the EU Return Directive:

• Return decision. A person staying irregularly is normally given a return decision, usually with a period to leave voluntarily.
• Entry ban. An entry ban must be added if no voluntary departure period was given or you did not leave within it, and may be added in other cases. Its length depends on the circumstances and should not in principle exceed 5 years, longer only for a serious threat to public policy or security.
• Schengen-wide effect. An entry ban is entered in the Schengen Information System, and border guards in every Schengen country check it on entry.

Each country applies its own procedures on top, so the practical outcome for a few days' overstay varies. If you were forced to overstay by unforeseeable and serious events, the EES Regulation lets you ask for your record to be corrected, with evidence.

United Kingdom: the 30-day line

The UK's refusal grounds are in Part Suitability of the Immigration Rules, which replaced Part 9 in November 2025. For an adult, an overstay counts as a breach of immigration law unless it is disregarded. It is disregarded if you left the UK voluntarily, not at the Home Office's expense, and the overstay was 30 days or less (90 days or less if it began before 6 April 2017). Short overstays caused by an in-time application that was refused, then followed within 14 days by a new application, are also excepted.

A breach that is not disregarded leads to mandatory refusal of a visa or permission to enter for a set period, counted 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 to removal

2 years

Voluntarily, at public expense, more than 6 months after that notice

5 years

Removed at public expense

10 years

After using deception in an application

10 years

Outside those periods, a past breach can still be a discretionary reason to refuse an application. The UK visitor limit itself is covered in the UK Standard Visitor "180-day rule".

United States: the I-94 date decides

Your authorized stay is the "admit until" date on your I-94 record, which CBP creates when you arrive. You can look it up on CBP's I-94 website or the CBP Link app. Staying past it has consequences that start on the first day:

• Your visa is void. Under INA section 222(g), a visa is void once you remain beyond your authorized stay, even by one day. You then generally need a new visa from a consulate in your country of nationality.
• Unlawful presence bars. More than 180 days but less than a year of unlawful presence in a single stay, followed by departure, makes you inadmissible for 3 years. One year or more makes it 10 years.
• No more Visa Waiver Program. A traveler who did not comply with the conditions of an earlier VWP admission, such as the 90-day limit, is no longer eligible for the program and has to apply for a visa. See the US Visa Waiver Program 90-day limit.
• Visa bonds. Since 3 August 2026 a permanent program lets consular officers require B-1/B-2 applicants from designated countries to post a bond of up to $20,000. A bond that is breached, for example by overstaying, is generally forfeited.

Detection has tightened too. Since 26 December 2025, CBP may collect facial biometrics from all non-citizens on entry and exit at airports, land ports and seaports, which it uses to identify overstays. The B-1/B-2 limit is explained in the US B1/B2 180-day limit.

Common stay limits

Each system counts differently, so the same trips can be legal in one country and an overstay in another.

If you have already overstayed

1. Leave as soon as you can. In the UK and the US the length of the overstay decides the consequence, and the 30-day and 180-day lines are fixed.
2. Keep proof of when you left. Boarding passes, tickets and passport pages show your exit date if an official record is missing or wrong.
3. Answer honestly on future applications. Visa forms ask about past overstays. In the UK, deception in an application carries its own 10-year ban, far longer than most overstays would.
4. Get advice before you apply again. A regulated immigration adviser or lawyer in the country concerned can tell you which rules apply to your dates, whether an exception covers you, and whether a waiver exists.

Beyond the day count

Staying within your limit avoids an overstay; it does not guarantee your next entry. Border officers still judge whether you are a genuine visitor, and a pattern of stays close to the limit can draw questions on its own. Long stays can also make you tax resident under a separate test, such as the 183-day rule or the US Substantial Presence Test, which count the same trips differently.

AtlasDays counts down to your stay limit automatically

Log your trips once. Presets such as Schengen 90/180 Short-Stay Rule, UK Standard Visitor, US ESTA and US B-1/B-2 Visitor Visa show how many days you have left, privately on your iPhone, and Custom Visa or Entry Limit takes the limit on your own visa or entry permission. With AtlasDays Pro, Smart Alerts notify you when the days remaining reach the thresholds you choose, before the limit.

FAQ

Does the Schengen area know if I overstay by a few days?

Yes. Since 10 April 2026 the Entry/Exit System records every entry and exit of non-EU short-stay travelers digitally and automatically identifies stays that exceeded the maximum. EES keeps the records for 3 years after you leave, or 5 years if no exit is recorded, and what follows depends on the country where you are.

Is there a grace period for overstaying in the UK?

Not a grace period, but an overstay of 30 days or less is disregarded under the Immigration Rules if you leave voluntarily and not at the Home Office's expense. Above 30 days, leaving voluntarily at your own expense still brings a 12-month ban on returning.

What happens if I overstay my US visa by one day?

Your visa becomes void under INA section 222(g), and you will generally need to apply for a new one in your country of nationality. The 3-year and 10-year bars only start after more than 180 days of unlawful presence, but a Visa Waiver Program traveler who overstays loses eligibility for the program.
