Thailand is a common first stop in Southeast Asia, with travelers landing in Bangkok before heading to the islands or north to Chiang Mai. Since 15 September 2026, US citizens get 30 days visa-free instead of the 60 days previously allowed.
If you entered before 15 September 2026, you keep the period stamped in your passport at that time. One 30-day extension is possible at a Thai immigration office if you need more time.
