Good to know

Stays cut to 30 days. Visa-free stays for tourism went down from 60 to 30 days on 15 September 2026. If you arrived before then, you can stay until the date on your entry stamp.

Fake arrival card sites. The TDAC is free on the official site, tdac.immigration.go.th. Other sites look official but charge a fee.

Proof you'll leave. Border officers can ask to see a ticket out of Thailand within 30 days, where you're staying, and that you have enough money: 20,000 baht per person or 40,000 baht per family. People have been refused entry without this.

Tourism only. Visa-free entry is for tourism. For business or work, get the right visa before you travel.
