What should I do if I'm facing a visa overstayed situation in Thailand due to incorrect flight booking?

The user received their UK passport but noticed their entry stamp allows them to stay in Thailand until December 20, 2025, which conflicts with their return flight on January 20, 2026. Community responses clarified that the stamp is valid for 60 days from the arrival date, and extending the stay for an additional 30 days can start on the date of the current stamp expiration. They were advised that as long as they pass through customs before midnight on the day before their flight, they will not incur any fines for overstaying. Users noted that an overstay of fewer than 24 hours is generally waived from penalties.
