How it works
Stay calm and ask how they counted. Dates are the usual cause, like a missing exit or a stamp read wrong.
Show your evidence
Open Show at the border for every entry and exit in the window, plus boarding passes, bookings and your passport stamps.
If they give you a different date, log it. The date they write down is the one that counts.
If something goes wrong, ask for the decision in writing and talk to an immigration lawyer.
Mistakes people make
- Arguing from the app. Show dates and documents, not a countdown.
Where this comes from
Government sources only. Read the rule yourself.
