What Is the Thailand Marriage Visa?
The Non-Immigrant O Visa based on marriage allows foreign nationals legally married to Thai citizens to reside in Thailand long-term. Once granted and extended, it provides a one-year stay that can be renewed annually as long as the marriage and financial requirements remain valid.
Unlike the retirement visa, the marriage visa permits work in Thailand, but only with a separate work permit issued by the Ministry of Labour. It's one of the most popular long-term visa pathways for foreigners building a life in Bangkok.
Financial Requirements
You must meet ONE of two financial criteria. Option A: Maintain a Thai bank account in your name with at least ฿400,000 deposited. The funds must be seasoned for at least 2 months before applying for extension. Option B: Demonstrate monthly income of ฿40,000 or more, verified through an income letter from your embassy or evidence of foreign transfers.
A combination approach (savings plus income totaling ฿400,000 annually) is also accepted at some Immigration offices, though Bangkok's Chaengwattana office tends to be stricter than provincial offices.
Required Documents
Essential paperwork includes your passport with valid Non-Immigrant O entry, original Thai marriage certificate (Khor Ror 2 and Khor Ror 3), spouse's Thai ID and house registration (Tabien Baan), photos of you and your spouse together at home, joint photos at recognizable locations, a hand-drawn map to your residence, and TM.7 extension form.
Bring multiple sets of copies. Immigration officers often request additional supporting evidence such as joint bank statements, photos with extended family, or wedding ceremony pictures to verify the marriage is genuine.
Extension Process at Chaengwattana
Extensions are processed at Bangkok Immigration Bureau in Chaengwattana (Building B). Arrive before 7:30 AM to secure a queue number. The extension fee is ฿1,900. Both you and your Thai spouse must appear in person for the interview.
Upon approval, you receive a one-year extension stamp. Apply for re-entry permits (฿1,000 single, ฿3,800 multiple) if you plan to leave Thailand during the year, otherwise your visa becomes void upon departure.
90-Day Reporting Obligations
All long-term visa holders must report their address every 90 days. You can file in person at Immigration, by mail (send 15 days before due date), or online via the Immigration Bureau's e-service portal. Late reporting incurs a ฿2,000 fine; missing the report can complicate future extensions.
