Marriage Visa Thailand 2026: Complete Guide for Spouses of Thai Nationals

The Non-Immigrant O visa on the basis of marriage to a Thai national (commonly called the "marriage visa") is the primary long-term visa option for foreigners married to Thai nationals. It provides a 1-year permission to stay, extendable annually in Thailand, with a multiple-entry option available. Requirements: a legally registered marriage to a Thai national (the marriage must be registered at a Thai amphoe/district office — a wedding ceremony alone is not sufficient for immigration purposes); proof of financial stability; documentation. Financial requirements: one of the following must be demonstrated — 400,000 THB deposited in a Thai bank account in your name (the account must be seasoned — held for at least 2 months before application and 3 months after); or provable monthly income of at least 40,000 THB ($1,100 USD) per month via a letter from your embassy confirming income; or a combination of income and savings totalling 400,000 THB annualised. Documents required: valid passport; TM.7 application form; marriage certificate (Thai) with certified translation if issued abroad; Thai spouse's ID card and tabien baan (house registration); 4 passport photos; evidence of relationship (photos together, lease agreement with both names, etc.); bank book and letter from bank confirming balance (if using bank method). Application: apply at the Immigration Bureau — either at the nearest provincial immigration office or at the Bangkok Immigration Bureau (Chaeng Wattana). Processing typically takes 1–2 hours on the day if documents are complete. Annual extension (TM.30 required — your Thai spouse must report your residence): same financial requirements; apply 30 days before the current permission expires. Work permit: the marriage visa alone does not permit working in Thailand. A separate work permit must be obtained through an employer or business registration. 90-day reporting: required. Can be done online via the immigration bureau app or website.
