How long before my visa expires should I apply for an extension?

Apply 2-4 weeks before expiry. Don't wait until the last day—immigration offices can be backed up, and incomplete applications mean return trips.

What happens if I overstay?

Overstaying results in fines (500 THB/day, max 20,000 THB) and potential bans. Beyond 90 days overstay, you face detention and multi-year re-entry bans.
