Requirements vary by nationality and intended length of stay.
Many countries' citizens (USA, UK, Canada, Australia, most EU nations) enter Thailand without a visa for tourism. This exemption permits stays of up to 30 days for air arrivals. Land arrivals have permitted stays of 15 or 30 days. This period often extends at an immigration office in Thailand.
Specific documents for entry are important, regardless of visa status.
The official currency is the Thai Baht (THB). Major international currencies readily exchange at banks, licensed exchange booths, and some hotels. ATMs are widely available. Local exchange booths often provide better rates than banks or airport counters.
