Thailand Marriage Visa (Non-Immigrant O)

Who This Is For

Any foreign national who is legally married to a Thai citizen and wishes to live in Thailand long-term. There is no age requirement — spouses of any age qualify if the marriage is legally valid in Thailand.

Key Requirements

Valid marriage to a Thai national: your marriage must be legally recognised in Thailand. Thai marriages registered at the amphur (district office) are automatically valid. Overseas marriages require legalisation and a certified Thai translation. Until Thailand's Hague Apostille accession takes effect on 28 February 2027, an apostille alone will be refused — the certificate needs authentication in the issuing country, then legalisation at the Royal Thai Embassy.

Financial: 400,000 THB in a Thai bank account (in your name, not a joint account), maintained for 3 months before each annual extension. Alternatively: combined household income of 40,000 THB/month. The bank balance must be in a Thai bank account — overseas balances are not accepted for the in-country annual extension.

Your Thai spouse: must be a Thai citizen with a current national ID card and Tabien Baan (household registration). Your spouse will need to provide copies of both documents for your extension applications, and is strongly encouraged to attend the first extension appointment with you.

What Documents Are Needed

For the initial overseas visa application (at the Thai consulate in your country): • Passport • Marriage certificate (Thai amphur certificate, or home-country certificate legalised for use in Thailand — see below — + certified Thai translation) • Thai spouse's national ID card copy • Thai spouse's Tabien Baan copy • Evidence of cohabitation and relationship • Overseas bank statement showing financial means

For annual in-country extensions: • Above documents (updated versions) • Thai bank passbook and bank letter showing 400,000 THB balance • TM30 on file for current address • Photographs of you and your spouse together • 1,900 THB extension fee

Overseas Marriages — Legalisation Requirement

If you married outside Thailand (in Australia, the UK, USA, etc.), your home-country marriage certificate must be legalised before Thai Immigration will accept it. Until 28 February 2027 an apostille alone is refused: the certificate needs authentication in the issuing country and then legalisation at the Royal Thai Embassy. For Australians: until 28 February 2027 the document you need from the Department of Foreign Affairs and Trade (DFAT) is an authentication, not an apostille — allow 2–4 weeks. Visa Centre can advise on the process and required format for the certified Thai translation.
