Who can get a Thai marriage visa
The marriage visa is a Non-Immigrant O visa for foreigners legally married to a Thai national. Your marriage must be registered in Thailand at a district office (amphur), or a foreign marriage must be registered there, so immigration can see the Thai marriage certificate.
Money rules for the marriage visa
- Deposit: 400,000 THB in a Thai bank account in your name, usually held for at least two months before your first application and three months before each renewal.
- Income: at least 40,000 THB a month, shown with an embassy income letter or evidence of regular income.
- Immigration officers can ask how the funds are kept between renewals, so do not empty the account after approval.
These are lower than the retirement visa (800,000 THB or 65,000 THB a month), which is why many couples choose the marriage route even when the foreign spouse is over 50.
How the marriage visa works
Get a 90-day Non-O
Apply for a Non-O visa based on marriage through the Thai e-Visa system from your country of residence, or ask immigration whether your current stay can be converted.
Prepare the extension file
Season the funds, gather the marriage and household documents, and make sure your address is reported (TM30).
Apply for one year on Samui
File the one-year extension at the Koh Samui immigration office. Officers interview the couple and may visit your home before approving it.
Documents immigration asks for
- Form TM.7, passport photos and the 1,900 THB fee
- Passport with copies of all relevant pages
- Thai marriage certificate (Kor Ror 3) and marriage registration (Kor Ror 2)
- Your spouse's Thai ID card and house registration (tabien baan)
- Bank letter and bank book, or proof of monthly income
- Birth certificates of any children
- Photos of the couple together at home, and a map to your home
- Your spouse usually attends the appointment
The exact list varies slightly between immigration offices. The Koh Samui office in Maenam can tell you what it expects, or a visa specialist can prepare the file. Koh Samui immigration guide
Can you work on a marriage visa?
Yes, with a work permit. The marriage visa makes a work permit easier to obtain than other visas, but you still need one before taking any job or running an active business in Thailand.
Want it handled for you?
A licensed visa specialist can check your marriage documents, prepare the extension file and advise on the work permit.

Thai marriage visa FAQ
How much money do I need for a Thai marriage visa?
400,000 THB in a Thai bank account, or a monthly income of at least 40,000 THB.
Do I have to leave Thailand to renew a marriage visa?
No. The one-year extension is renewed each year at your local immigration office, such as the one on Koh Samui, as long as you remain married and meet the money rules.
Is there an age requirement?
No. Unlike the retirement visa, the marriage visa has no minimum age.
Can I work on a Thai marriage visa?
Only with a work permit. The visa itself does not allow work.
What if my marriage was registered abroad?
You can register a foreign marriage at a Thai district office, usually after legalising the certificate, so you hold the Thai documents immigration asks for.
