Thailand Entry Requirements for U.S. Citizens

Entry Requirements for U.S. Citizens: Thailand

Note: Entry rules are generally stable but can change - check with the Royal Thai Embassy in Washington, D.C. or the U.S. Department of State before traveling.

Passport & Visa Requirements

• Passport validity: Your U.S. passport must be valid for at least six months beyond your date of entry.
• Blank pages: At least one blank page is required for entry and exit stamps.
• Visa requirement: U.S. citizens do not need a visa for stays of up to 30 days but do need a Thailand Digital Arrival Card.
• Longer stays: Travelers who wish to stay longer than 30 days must obtain a tourist visa (typically valid for 60 days and extendable for 30 more days) from a Thai embassy or consulate before traveling.
• Multiple entries: Frequent entries may raise questions from immigration officers, who may deny entry if they suspect misuse of visa exemptions to live in Thailand long-term.

Entry Procedures

• Onward/return ticket: Travelers must present proof of onward or return travel when entering under the visa exemption.
• Proof of funds/accommodation: Travelers may be asked to show hotel reservations and proof of sufficient funds (at least 10,000 THB per person or 20,000 THB per family in cash).
• Entry points: Entry is possible by air, land, or sea at official ports of entry.

Health & Vaccinations

• Routine vaccinations: No mandatory vaccinations are required for travelers arriving from the U.S.
• Yellow fever: A yellow fever vaccination certificate is required only if arriving from or transiting through a country with yellow fever risk.
• COVID-19: There are no COVID-related entry requirements (no testing or proof of vaccination as of 2025).
• Health insurance: Not required for entry, but strongly recommended as medical care must be paid for upfront.

Traveling with Minors

• Parental authorization: No special published entry requirements exist, but a notarized parental consent letter is recommended if a child is traveling alone or with only one parent.

Additional Restrictions & Considerations

• Currency declaration: Travelers must declare if carrying over USD $20,000 (or equivalent) in cash when entering or leaving Thailand.
• Security advisory: The U.S. Department of State currently advises Level 1: Exercise Normal Precautions in most of Thailand, and Level 3: Reconsider Travel to the provinces of Yala, Pattani, Narathiwat, and parts of Songkhla due to periodic violence.
• Overstays: Overstaying your permitted stay can result in fines, detention, deportation, and bans on reentry.
