United States entry requirements for Thailand passport holders
Thai passport holders need a visa to enter the United States. There is no visa-free or visa-on-arrival option, and you must apply for a B-1/B-2 visitor visa at a U.S. embassy or consulate before you travel. Plan ahead—appointments and processing can take several weeks.
Entry requirements
| Requirement | Details | Status |
|---|---|---|
| US visa (B1/B2 or other appropriate category)You cannot enter the US without a valid visa; the eVisa option is not open to Thai passport holders. Apply at a US embassy or consulate | Thai citizens must obtain a nonimmigrant visa (e.g., B1/B2 for tourism or business) before traveling to the United States. The eVisa program is not available for Thai nationals; you must apply in person at a US embassy or consulate, attend an interview, and pay the application fee. | Required |
| Passport validityUS immigration requires your passport to remain valid for 6 months after your trip ends. At least 6 months beyond your intended stay | Your Thai passport must be valid for at least 6 months beyond your planned departure date from the United States. If your passport expires sooner, renew it before applying for a visa or traveling. | Required |
| Blank passport pagesThe visa officer and border officer need a clean page to place stamps. At least 1 blank page for the visa stamp | Your passport must have at least 1 blank page (front and back) for the US visa and entry/exit stamps. If you have fewer blank pages, obtain a new passport before your visa interview. | Required |
| Return or onward ticketUS entry rules require evidence that you will leave the country before your visa expires. Proof of departure from the US | You must have a confirmed return or onward ticket to a country other than the United States. This is typically checked at check-in and by US Customs and Border Protection upon arrival. | Required |
| Proof of fundsCarry documents that show you can pay for your trip without working illegally. Sufficient financial means for your stay | You may be asked to show evidence of sufficient funds to cover your expenses during your stay in the US, such as bank statements, credit cards, or a sponsor's letter. The amount is not fixed but should match your planned activities. | Recommended |
| Arrival declarationYou don't need to fill out any special form before flying; just complete the usual arrival procedures. Not required for Thai citizens | No separate arrival declaration (such as a customs or immigration form) is required for Thai citizens entering the United States. You will complete the standard CBP declaration form upon arrival, either on paper or via the CBP One app. | Not required |
| eVisa applicationDo not attempt to apply for an eVisa; it is not an option for your nationality. Not available for Thai passport holders | The US does not offer an eVisa for Thai citizens. You must apply for a visa through the traditional embassy/consulate process, including scheduling an interview and submitting biometrics. | Not required |
