Visit the Royal Thai Embassy website for the most current visa information.

• U.S. citizen tourists entering Thailand for fewer than 60 days do not require a visa but pre-arrival online registration is required. We strongly recommend that your passport be valid for at least six months beyond the date of your arrival in Thailand to avoid possible denied entry.
• Thai immigration officials or airline staff may ask for your onward/return ticket or financial ability to remain in Thailand.
• Business travelers, U.S. government employees travelling on official business, teachers, retirees, and those planning to stay longer than 60 days should check with the Royal Thai Embassy about visa requirements.
• If you overstay your visa, you will be fined. Depending on the length of overstay, you may also be arrested, detained, deported at your own expense, and banned from re-entering Thailand.

We strongly recommend you always carry a digital or physical copy of your U.S. passport identification page and current Thai visa while in Thailand to help avoid detention by the Thai immigration police.

Thailand’s entry/exit information is subject to change without notice. For the most current information, please see The Royal Thai Police Immigration Bureau.
