Thailand Marriage Visa: Non-Immigrant O for Thai Spouses
Updated 2026-07-05
The Thailand marriage visa is a Non-Immigrant O visa based on marriage to a Thai national. You enter on a 90-day visa, then apply for 1-year extensions inside Thailand. The financial requirement is 400,000 THB held in a Thai bank for two months before applying, or proof of 40,000 THB per month in income.

What the marriage visa is and how the path works
What everyone calls the Thailand marriage visa is formally a Non-Immigrant O visa issued on the basis of marriage to a Thai national, followed by one-year extensions of stay granted inside Thailand. The visa gets you in the door for 90 days; the extension is what you actually live on.
The typical path has two steps. First, obtain the 90-day Non-O, either online before travel or, in some cases, by converting an eligible entry at immigration in Thailand. Second, once you meet the financial requirement, apply for the one-year extension at your local immigration office before the 90 days run out.
Compared with the retirement visa, the marriage route has no age requirement and a lower financial bar, 400,000 THB against 800,000. The trade-off is more paperwork, and an annual renewal that examines the marriage as well as the money.
The financial requirement: two routes
Route one is money in the bank: 400,000 THB (roughly 11,000 USD) in a Thai bank account in your sole name, held for at least two full months before the extension application. Immigration verifies this with a bank letter and statements, so the seasoning period is a hard rule, not a guideline.
Route two is income: 40,000 THB per month. Proving it is where offices differ. Depending on the office, you will need an income letter from your embassy or Thai tax records showing the income, and several embassies, including the US and UK, no longer issue income letters at all. Check what your specific office accepts before committing to this route.
Practical advice: if you can fund the bank route, use it. It is objective, verifiable, and argued over far less at the counter. The income route works, but it works differently at different offices, which is a poor foundation for an annual ritual.
Documents you will need
The marriage must be legally registered, which for weddings in Thailand means the district office registration, not just the ceremony. The core documents revolve around proving the marriage, your spouse’s identity and address, and your finances.
The photo requirement surprises people: immigration wants photos of the two of you together at your home, typically including shots showing the house number and the two of you inside the house. Offices ask because they verify the marriage is real and cohabiting, and a home visit or a call to your spouse can be part of the first extension.
- Marriage certificate and registration (Kor Ror 2 and Kor Ror 3)
- Spouse’s Thai ID card and house registration (tabien baan), signed copies
- Your passport with the Non-O visa and entry stamp
- Bank letter and statements for the 400,000 THB, or income evidence per your office
- Photos of you and your spouse together at your home
- TM.7 extension form, photo, and 1,900 THB fee
The application process, step by step
Before travel, apply for the 90-day Non-O through the official e-visa portal with your marriage documents; processing takes about 3 to 7 business days. Already in Thailand on another status? Ask your local immigration office about converting in-country; it is possible in many cases but adds steps and depends on your current entry.
After arrival, open a Thai bank account if using the bank route and deposit the 400,000 THB immediately, because the two-month seasoning clock only starts then. That timing is tight against a 90-day entry, which is why the deposit should be the first errand, not the last.
File the extension at your local office with your spouse present. Marriage extensions are typically not approved on the spot: expect an under-consideration period of around 30 days, during which the office may visit your home or call your spouse, before the full year is stamped.
Staying compliant year to year
The extension renews annually, with the same financial evidence each time, and the 400,000 THB must again be seasoned two months before each renewal. Many couples simply leave the money in place year-round, which is simpler and avoids a scramble before every renewal date.
Between renewals, two obligations continue. You must file a 90-day address report, free and often online, for every 90 days of continuous stay. And if you travel abroad, buy a re-entry permit before leaving; departing without one voids the extension, which is a brutal way to lose a year of status.
Working on a marriage visa
A real advantage of the marriage route: you can be granted a work permit while on it, without needing to switch to a Non-Immigrant B visa. Your employer applies for the permit, and holders married to Thai nationals also benefit from relaxed quota rules compared with standard work-permit sponsorship.
The visa itself still does not authorize work; the work permit does. Keep the two documents in sync, because losing the job does not end the visa, but working after the permit lapses is illegal employment. If the marriage ends, the basis of the visa ends with it, and you would need to move to another category at the next renewal.

Frequently asked questions
What are the financial requirements for a Thailand marriage visa?
Either 400,000 THB in a Thai bank account in your name, held for at least two months before the extension application, or income of 40,000 THB per month. The bank route is verified with a bank letter and statements and is treated consistently everywhere. The income route depends on the office: some accept an embassy income letter, others want Thai tax records, so confirm locally first.
Can I work in Thailand on a marriage visa?
Yes, with a work permit. The marriage-based Non-O is one of the few non-work visas that supports a work permit application, so you do not need to switch to a Non-Immigrant B. Your employer files for the permit, and spouses of Thai nationals face relaxed quota requirements. The visa alone does not authorize work; until the permit is issued, employment remains illegal.
What are Kor Ror 2 and Kor Ror 3?
They are the official Thai marriage documents issued by the district office (amphoe): the Kor Ror 3 is the marriage certificate issued at registration, and the Kor Ror 2 is the marriage registration record extracted from the registry. Immigration asks for both at extension time, and offices often want a recently issued Kor Ror 2. Your spouse can obtain copies from a district office.
Does immigration really visit your home?
It happens, particularly around the first one-year extension. Officers may visit the address, photograph you together there, or phone your spouse with questions, which is also why the application includes photos of you both at home. Extensions typically sit under consideration for around 30 days while these checks run. For genuine, cohabiting couples the process is intrusive but routine.
What happens to the visa if we divorce or my spouse dies?
The marriage is the legal basis of the visa, so divorce removes that basis and the extension cannot be renewed on marriage grounds; you would switch to another category, such as retirement if you are 50 or older, or a visa based on supporting a Thai child if applicable. Existing permissions are not canceled overnight, but plan the transition before your next renewal date rather than at it.
How long does the marriage visa extension take to be approved?
Unlike tourist extensions, the one-year marriage extension is usually not finished the same day. Most offices take the application, stamp a roughly 30-day under-consideration period, and complete verification, sometimes including a home visit or a call to your spouse, before stamping the full year. You remain legally in Thailand throughout. Bring your spouse to the appointment; offices expect it.
