U.S. Citizen Services

Welcome to American Citizen Services (ACS) for U.S. Mission Thailand. We provide a range of services and information. All non-emergency consular services, including passport applications, notarizations and reports of birth abroad, require an appointment. We will not accept walk-ins. This assists us in providing prompt and efficient consular services to American Citizens residing in and visiting Thailand.

NOTICE: Beginning January 1, 2019, U.S. Embassy Bangkok and U.S. Consulate General Chiang Mai will no longer provide the income affidavit. We will not notarize previous versions of the income affidavit. For more information, please refer to our Fact Sheet (PDF 266 KB) and Frequently Asked Questions (PDF 419 KB). We will continue to notarize income affidavit forms through the end of 2018. Thai Immigration Bureau officials confirmed that they will support early visa renewals for U.S. citizens during the transition period.

We provide American Citizen Services at the U.S. Embassy in Bangkok and the U.S. Consulate General in Chiang Mai.

Below you will find links to popular services we offer at the Embassy or at other government institutions. For a full list of services offered by ACS Units, please click the information A-Z link.  For commonly requested forms and informational handouts, please click the appropriate link.
