Visa-Free Entry: 60 Days
As of the 2024 update, US citizens can enter Thailand visa-free for up to 60 days (previously 30 days). This applies to arrivals at any international airport or land border crossing. No advance application needed — you'll receive a stamp on arrival.
Extending Your Stay
You can extend your visa-free stay by 30 additional days (total 90 days) at any Thai Immigration office for a fee of 1,900 THB (~$55). The main office in Bangkok (Chaeng Watthana) is busiest — consider offices in Chiang Mai, Phuket, or Koh Samui for shorter queues. Bring your passport, a passport photo, a copy of your passport photo page, and the TM.6 departure card.
Longer Stays: Tourist Visa
If you plan to stay longer than 90 days, apply for a Tourist Visa (TR) at a Thai embassy or consulate before departure. The single-entry tourist visa allows 60 days (extendable by 30), while the multiple-entry tourist visa (METV) allows multiple 60-day entries over 6 months. Digital nomads should research the Long-Term Resident (LTR) visa.
Entry Requirements
Passport must be valid for at least 6 months. Technically, you should have proof of a return or onward flight and proof of funds (20,000 THB per person or 40,000 per family), though these are rarely checked at airports. Land border crossings may be stricter.
Common Mistakes to Avoid
Don't overstay your visa — Thailand charges 500 THB per day overstay (up to 20,000 THB), and overstays can result in detention and bans. Don't work on a tourist visa or visa-free entry. Don't do 'visa runs' too frequently — immigration may deny entry if they suspect you're living in Thailand on tourist status.
