Marriage Visa Benefits
Legal long-term stay with your Thai spouse
The Non-Immigrant O marriage visa is the most straightforward long-stay option for spouses of Thai nationals.
Year-round legal residence
Live with your spouse in Chiang Mai without tourist visa limitations or border runs.
Lower financial threshold
400,000 THB in a Thai bank or 40,000 THB/month income, lower requirements than the retirement visa.
Renewable indefinitely
Annual renewals with no end date, as long as your marriage is intact and you meet the financial threshold.
Work permit eligible
The O visa is the correct visa type to then obtain a Thai work permit if you find local employment.
Travel flexibility
A re-entry permit lets you leave and return to Thailand without losing your visa status.
Family stability
Settling your long-term legal status removes uncertainty from the relationship and enables proper life planning in Thailand.

Eligibility, documents, the application process, and what you can and can't do on the Non-Immigrant O.
Who qualifies for the marriage visa
Two requirements: a legal marriage to a Thai national, and meeting the financial threshold.
Two things qualify you for this visa: your marriage is legally registered, and you meet the financial threshold below. That's it. Immigration is checking paperwork, not judging your relationship.
Your marriage must be registered at a district office (amphoe) in Thailand, or if married abroad, your marriage certificate must be legalised and translated into Thai. Common law relationships and long-term partnerships without legal registration don't qualify for this specific visa category, but a legally registered marriage of any length does.
You must meet one of these three financial routes:
Bank Deposit Route
400,000 THB
Held in a Thai bank for the required period before and after your application.
Monthly Income Route
40,000 THB/month
Transferred to a Thai account from abroad on a regular basis.
Combination Route
Income + savings = 400,000 THB
Example: 20,000 THB/month income (240,000 THB/year) plus 160,000 THB in savings.
The deposit timing is strictly enforced, so we advise every client on the correct schedule before they fund the account.
If you are already in Thailand on a tourist visa or exemption, you can apply for the Non-Immigrant O at Chiang Mai immigration. This is the most common route for our clients who are already living with their spouse here.
As of 22 January 2025, Thailand's Marriage Equality Act grants same-sex couples full marriage equality, making Thailand the first country in Southeast Asia to do so. Same-sex couples where at least one partner is a Thai national can register their marriage at a district office (amphoe) on the same basis as any other couple.
The marriage certificate issued (a Kor Ror 3) is the same document regardless of the couple's gender, and is accepted by Thai immigration on the same terms. Same-sex married couples therefore qualify for the Non-Immigrant O marriage visa on identical grounds, with the same financial thresholds and documentation requirements.
Expert Insight
Bank deposit timing is the most common reason marriage visa applications are delayed or rejected. The 400,000 THB must be in the account for a set number of days before you apply. We advise every client on the exact schedule.
Documents you'll need
Both you and your Thai spouse provide documentation. We prepare and check everything before submission.
- Passport valid for at least 18 months with blank visa pages
- Recent passport-style photographs
- Completed Non-Immigrant O application form
- Proof of current visa or entry stamp
- Thai bank book and bank letter confirming the 400,000 THB deposit (or income evidence)
- Official Thai marriage certificate (Kor Ror 3) from the district office
- If married abroad: original marriage certificate, legalised with apostille and translated into Thai by a certified translator
- Thai national ID card (front and back)
- Thai household registration book (tabien baan), ideally showing the shared address
- Spouse's house registration certificate
- Proof of your address in Chiang Mai: lease agreement or TM30 house registration
- Your landlord must file a TM30 with immigration when you move in (we handle this reminder)
Expert Insight
Foreign marriage certificates need legalisation and certified Thai translation, a process that takes 2–4 weeks. We flag this at the start so it doesn't delay your application at the end.

What you can & can't do
Not without a work permit. The Non-Immigrant O marriage visa gives you the right to live in Thailand, but not to work. To work legally you need a work permit issued by the Department of Employment, which typically requires employer sponsorship. We can refer you to the right contacts if you need a work permit.
Yes. If you stay in Thailand for more than 90 consecutive days without exiting, you must file a 90-day report. We handle this for all ongoing clients.
Yes, but you need a re-entry permit before you exit: either a single (1,000 THB) or multiple (3,800 THB) re-entry permit. Leaving without one cancels your visa and you must apply again from scratch.
This is a hard question to face, and we handle it with the same care we'd want for our own family. If your marriage to a Thai national ends (through divorce or the death of your spouse), you're no longer eligible for the marriage visa on that basis, but you do have other options.
Contact us as early as you're able to. We'll talk through what applies to your situation (often a guardian visa if you have children in school here, or another visa category) and plan the transition with you, not just at you.
