Visa-free for tourism; file the free TDAC online before arrival
US citizens do not need a visa for short tourist trips to Thailand. You currently get 60 days visa-free, but Thailand has approved cutting that to 30 days, effective once published in the Royal Gazette and not yet in force as of June 2026. Every arrival must file the free TDAC online.
US citizens do not need a visa for short tourist trips to Thailand. You currently get 60 days visa-free, but on May 19, 2026 Thailand approved cutting that to 30 days, effective 15 days after it is published in the Royal Gazette — not yet in force as of June 2026. Plan for 30 days and verify at travel.state.gov before booking.

There are no nonstop flights from the US mainland — United and Delta connect through Tokyo, and Bangkok sits about 11 hours ahead of US Eastern time, so plan for heavy jet lag. Buy travel insurance; Medicare won't cover you abroad.

Step by step: getting into Thailand
Before you fly
- 1Confirm passport valid 6+ months — Thailand expects your US passport to be valid at least 6 months beyond your arrival date. Renew early if you're close.
- 2File your free TDAC online — Within 72 hours before arrival, complete the Thailand Digital Arrival Card at tdac.immigration.go.th. It is free and takes under 5 minutes. Avoid paid copycat sites.
- 3Budget for a 30-day stay — A cut from 60 to 30 days was approved May 19, 2026, effective 15 days after Royal Gazette publication. Verify your allowance at travel.state.gov before you book.
At immigration
- 1Show your TDAC QR code and onward ticket — Have your TDAC confirmation, return or onward ticket, and hotel address ready. Officers may ask for proof of funds.
- 2Get your entry stamp — Immigration stamps your visa-exempt period in your passport. Check the date — it sets your departure deadline.
After you arrive
- 1Track your stamped exit date — Overstaying Thailand carries fines of 500 THB per day and possible bans. Count from the stamped date, not your flight.
- 2Extend at immigration if needed — You can extend a visa-exempt stay once by 30 days for 1,900 THB (≈ $52) at a Thai immigration office.
Common mistakes to avoid
1.Will I get 60 days or 30 days in Thailand right now?
→ As of June 2026 the visa exemption is still 60 days, but a cut to 30 days has been approved and may take effect soon. Plan for 30 days and verify at travel.state.gov before you fly.
2.Is the TDAC the same as a visa?
→ No. The TDAC is a free arrival card every visitor must file online before arrival. It is not a visa and does not change how long you can stay.
3.My passport expires in 5 months — can I enter Thailand?
→ Probably not. Thailand expects at least 6 months of validity beyond arrival. Renew before you travel to avoid being turned away at check-in.
4.A website charged me to file the TDAC — is that right?
→ No. The official TDAC at tdac.immigration.go.th is free. Paid sites are third-party resellers; you never need to pay for the arrival card.
You'll want a local SIM or eSIM on arrival:
