Passport holders of the listed nationalities may enter Thailand without a visa for stays of up to 30 days. No stamp or pre-arrangement is required — the exemption is granted on arrival at any international port of entry. Entry via land border is permitted a maximum of twice per calendar year; entry by air has no such restriction. Complete the Thailand Digital Arrival Card (TDAC) online before departure. Ensure your passport has at least 6 months of remaining validity and that you can show a return or onward ticket and proof of sufficient funds (20,000 THB per person / 40,000 THB per family). Extensions of up to 30 additional days can be requested at any Immigration office inside Thailand.
