A visa built around your marriage, not against it
For foreign nationals married to a Thai citizen who intend to build a life in Thailand on a Non-Immigrant O visa and its annual extension — assembled with the financial and relationship evidence immigration expects.
Marriage is the easy part. The file is where applications are won or lost.
The marriage-based extension rests on two pillars immigration scrutinises closely: a financial position of either THB 400,000 seasoned in a Thai bank account or THB 40,000 in monthly income, and credible proof that the relationship is genuine and the couple lives together. We seat the deposit on the correct timeline, document its source, and assemble the cohabitation evidence — photographs, the spouse's household registration, a residence map — before the file is ever presented.
We act for the applicant from the initial Non-Immigrant O entry through each annual renewal, and we prepare the household for the unannounced home visit that immigration may conduct to verify the marriage. We also coordinate the parallel obligations that derail otherwise sound cases — the 90-day address report and the re-entry permit that protects status before any travel — so nothing lapses between renewals.

Thailand Marriage Visa — eligibility & documents
Eligibility
- A foreign national legally married to a Thai citizen, with a marriage registered in Thailand or a foreign marriage recognized under Thai law.
- A financial position of THB 400,000 in a bank account in the applicant's name. For the initial 90-day entry, funds held at any bank are accepted. For the subsequent one-year extension of stay, the funds must be held in a Thai bank account, seasoned for at least two months before applying.
- A genuine and ongoing relationship — the couple lives together, and the file can demonstrate cohabitation through photographs, the shared residence, and supporting evidence.
- Willingness to accommodate a possible immigration home visit and neighbor interview to confirm the marriage is authentic.
- The applicant enters Thailand on a Non-Immigrant O visa, which grants an initial 90-day stay. The one-year extension of stay based on marriage is then applied for from within Thailand.
Required documents
- Passport with at least six months' validity.
- Marriage certificate — for the initial 90-day entry, a foreign marriage certificate is accepted. For the one-year extension, a Thai marriage certificate is required.
- Thai spouse's national ID card and house registration book (Tabien Baan), with copies.
- Proof of a genuine relationship — photographs of the couple together at the residence and in family settings.
- Financial evidence — a bank statement confirming a THB 400,000 balance in the applicant's name. For the initial 90-day entry, funds from any bank are accepted. For the one-year extension, an updated passbook and bank letter from a Thai bank confirming the balance seasoned for at least two months are required.
- Proof of residence in Thailand — a map to the marital residence and confirmation of the current address, required at the one-year extension stage.
- Completed extension application forms and the spouse's signed declarations of support.
