US passport holders can enter Thailand visa-free for up to 30 days — no advance application, no fee. You'll clear immigration on arrival at Suvarnabhumi, Don Mueang, Phuket, or wherever you land, and the stamp in your passport is your permission to stay. The 30-day clock starts the day you arrive, not the day you planned to leave.
Apply for Thailand eVisaSingle and multiple entry options. Processing 3–5 business days.
Entry requirements
| Requirement | Details | Status |
|---|---|---|
| Valid passport Must be valid for at least 6 months beyond your stay | Your passport needs at least 6 months of validity from your entry date. Airlines check this before boarding — if your passport expires sooner, you'll be denied at the gate. Immigration at Suvarnabhumi enforces this strictly. | Required |
| Return or onward ticket Proof of departure from Thailand | Immigration officers at Suvarnabhumi and Don Mueang routinely ask for a flight out within 60 days. Budget airlines like AirAsia and Nok Air check this at check-in and may deny boarding without it. A printed or digital booking confirmation works. | Required |
| Proof of accommodation Hotel booking or host address | Immigration rarely asks, but if you're flagged for secondary screening, they'll want to see where you're staying. A hotel confirmation email or a letter from a friend in Thailand is enough. | Recommended |
| Proof of funds 20,000 THB per person or 40,000 THB per family | The official requirement is 20,000 THB in cash or accessible funds. In practice, immigration almost never checks this for US passport holders, but carry a bank statement or ATM card just in case. | Recommended |
| Thailand Digital Arrival Card (TDAC)Thailand Digital Arrival Card — a free 2-minute online pre-registration at tdac.immigration.go.th. Not mandatory, but gets you through the immigration queue faster. Optional online pre-registration | TDAC is a free 2-minute form at tdac.immigration.go.th where you enter your passport, flight, and accommodation details. It's not mandatory, but having the QR code ready gets you through the immigration queue faster. The old paper TM6 card was scrapped in 2022.Open TDAC form | Optional |
The 6-month passport rule is enforced
Thai immigration requires your passport to be valid for at least 6 months from your arrival date. Airlines check this at check-in in the US and will deny boarding if you're short. Renew before you book if your passport expires within 8 months.
TDAC replaces the paper arrival card
You no longer fill out a paper card on the plane. Complete the Thailand Digital Arrival Card online at https://tdac.immigration.go.th within 3 days of arrival. It's free. Save the confirmation — you'll show it at immigration.
Onward ticket is checked at check-in
Airlines flying to Thailand routinely ask for proof you're leaving within 30 days. A one-way ticket with no onward booking is the most common reason US travellers get stopped at the departure gate. Have a booking ready.
Overstay fines add up fast
Overstaying your 30-day stamp costs 500 THB per day, up to 20,000 THB, and can get you banned from re-entering Thailand. Set a reminder for a few days before your stamp expires.
What happens at the border
1
Check your passport validity and blank pages
Do this before you book anything. You need 6 months of validity from your arrival date and at least one fully blank page. US passports can be renewed by mail, but it takes weeks, so don't leave it to the last minute.
2
Book your onward ticket within 30 days
Airlines at US departure airports will ask to see proof you're leaving Thailand within 30 days. Have the confirmation on your phone or printed. If you're planning to extend or do a border run, book a refundable onward ticket to satisfy the airline.
3
Fill out the TDAC online before you fly
Go to https://tdac.immigration.go.th and complete the form within 3 days of arrival. It's free. Save the confirmation email or take a screenshot — you'll show it at immigration. No paper card is handed out on the plane anymore.
4
At check-in in the US
Show your passport and onward ticket. The agent may ask where you're staying. This is routine. If you have a one-way ticket and no onward booking, expect to be asked to buy one before you can board.
5
On arrival at Thai immigration
At Suvarnabhumi (BKK), Don Mueang (DMK), Phuket (HKT), or Chiang Mai (CNX), join the foreign passport queue. Hand over your passport and the TDAC confirmation. You may be asked for your onward ticket or accommodation address. The officer stamps you in for 30 days. Keep the stamp — it's your legal permission to stay.
6
Keep track of your 30-day stamp
The date written in your passport is the day you must leave or extend. Overstaying even by a day means a fine of 500 THB per day, up to 20,000 THB, and can affect future entry. Set a phone reminder for a few days before.

Frequently asked questions
No. US passport holders enter Thailand visa-free for up to 30 days for tourism. You don't apply in advance, you don't pay a fee, and you get the stamp at immigration on arrival. The 30 days starts on your arrival date.
The visa-free entry itself isn't extendable in the usual sense, but you can apply for a 30-day extension at a Thai immigration office inside the country. The main offices are at Chaeng Wattana in Bangkok and in Phuket, Chiang Mai, and Pattaya. The fee is 1,900 THB. Processing is usually same-day if you arrive early. Bring your passport, a photo, and the fee in cash.
There's no hard published annual limit for US citizens, but Thai immigration has become stricter about back-to-back visa-free entries. If you're doing repeated border runs and spending most of the year in Thailand, you may be questioned or refused entry. If you plan to stay long-term, look into a proper long-stay visa rather than relying on visa-free entries.
The Thailand Digital Arrival Card replaced the old paper arrival card. You fill it out online at https://tdac.immigration.go.th within 3 days of arriving. It's free. You'll need your passport details, flight number, and where you're staying. Show the confirmation at immigration — a screenshot on your phone is fine.
You're fined 500 THB per day of overstay, capped at 20,000 THB. You pay at the airport immigration desk on your way out. Overstays of more than 90 days can lead to a ban from re-entering Thailand. Even a one-day overstay gets recorded, so don't cut it close.
Yes, officially. You need a ticket leaving Thailand within 30 days. Airlines enforce this at check-in more strictly than Thai immigration does. If you're not sure of your plans, book a cheap refundable flight or a bus ticket to a neighbouring country — it satisfies the requirement and you can cancel it later.
The Thai eVisa system at https://www.thaievisa.go.th/ exists, but US citizens don't need it for a standard 30-day tourist visit — visa-free entry is simpler and free. The eVisa is useful if you want a longer stay or a different visa category. For a normal holiday, just fly in and get stamped.
