Thailand Marriage Visa Guide

The marriage visa is not a single stamp. It is usually a Non-Immigrant O visa followed by a one-year extension of stay based on marriage to a Thai national. The Non-O gives 90 days; the extension, applied for in Thailand, gives a year and is renewed annually.

Because the extension is based on a relationship, the evidence is personal: the marriage registration, the household documentation, and evidence that the couple genuinely live together. Immigration reviews the relationship, not just the paperwork.

The standard is 400,000 THB in a Thai bank or 40,000 THB per month in income, or a combination. The funds must be seasoned for at least two months before the application. The threshold is lower than the retirement visa, reflecting that the basis is a relationship rather than retirement savings.

Where the foreign spouse cannot meet the financial requirement alone, a guarantor or the Thai spouse's income may be considered in some circumstances. We confirm what the local Immigration Office will accept before the application is filed.

The marriage must be registered at a Thai district office to support the extension. A religious or customary ceremony alone is not enough. The marriage certificate, the household registration, and evidence of cohabitation such as photos, joint accounts and a shared address are all part of the file.

Immigration sometimes interviews the couple, particularly at the first extension. The interview is not adversarial, but it does test whether the marriage is genuine. We prepare clients for what to expect so the interview confirms the relationship rather than raising doubts.

The extension is renewed each year, with the financial evidence re-filed and the relationship re-confirmed. 90-day reporting applies throughout. A re-entry permit is required for travel abroad during the year.

A marriage visa is often the first step toward permanent residence, which becomes available after three consecutive years on the same non-immigrant category. We track the eligibility so clients who want to move toward permanent residence do so on the right timeline.
