The details for a British passport.
30-day tourist visa exemption since 15 Sep 2026 (was 60 days from 15 Jul 2024 to 14 Sep 2026; arrivals on or before 14 Sep keep the stay stamped). Tourism only: business meetings and conferences need a visa. Extendable once by up to 30 days at a Thai immigration office (form TM.7, THB 1,900, officer's discretion). Thai embassies (London, Washington) and FCDO say the exemption may be used only twice per calendar year; TAT's summary of the Royal Gazette orders describes the two-per-year cap as applying to land-border entries. Immigration may ask for onward ticket within 30 days, accommodation and THB 20,000 per person / 40,000 per family. For longer stays apply for the TR e-Visa (60 days). TDAC arrival card required.
How long it must be valid.
At least 6 months remaining from the date of arrival.
