Marriage Visa Guide for Foreigners in Thailand (2025)
If you are legally married to a Thai citizen, you may qualify for a Thai Marriage Visa, officially known as a Non-Immigrant O Visa based on family reasons. This guide explains the requirements, process, and documentation for obtaining and renewing this visa under Thai law.

What Is a Thai Marriage Visa?
The Thai Marriage Visa allows a foreign spouse to legally stay in Thailand for up to one year and renew it annually. It is available to those who are married to a Thai national and meet financial and residency requirements.
Who Can Apply?
- You must be legally married to a Thai citizen (marriage registered in Thailand).
- You must hold a valid Non-Immigrant O visa (single or multiple entry).
- You must meet the financial requirements set by immigration.
- You must reside in Thailand legally and report your address as required.
Required Documents
Note: All documents must be in Thai or officially translated, with originals and copies.
Personal Documents
- Passport (with visa stamp)
- TM.6 departure card
- Thai marriage certificate (Kor Ror 3) and registration (Kor Ror 2)
- Thai spouse's ID card and house registration (Tabien Baan)
- Photos of the couple at home, inside and outside the house
- Map to your residence
Financial Proof (choose one)
- Option 1: Bank account in Thailand with minimum 400,000 THB, held for at least 2 months before application
- Option 2: Monthly income of at least 40,000 THB, proven by:
- Income letter from your embassy, or
- 12 months of Thai bank statements showing consistent deposits
Application Process
Step 1: Apply for a Non-Immigrant O Visa
If you are outside Thailand, you can apply for a 90-day Non-Immigrant O visa at a Thai embassy or consulate with your marriage documents and financial proof.
Step 2: Extend to a 1-Year Marriage Visa in Thailand
Before your 90-day visa expires, apply at your local immigration office. You will need to submit all documents, financial proof, and attend an interview if requested. If approved, the visa will be extended to 1 year.
Annual Renewal Process
- Marriage visa must be renewed every year at immigration
- You must still meet the financial and relationship requirements
- Provide new bank letters or income statements
- Update home address with TM.30 if you’ve moved
- File 90-day reports with form TM.47
Important Notes
- Unregistered marriages (e.g., religious or customary only) are not valid for visa purposes
- You must show evidence of genuine cohabitation
- Bank letters must show history, not just a current balance
- This visa does not allow work unless you obtain a separate work permit
Frequently Asked Questions (FAQ)
Can I work with a Marriage Visa?
No, not unless you also apply for a work permit with a Thai employer.
Can I convert a Tourist Visa to a Marriage Visa in Thailand?
Yes, but you must first change it to a Non-Immigrant O visa and then apply for the extension based on marriage.
What happens if I divorce?
You must inform immigration. Your visa may be cancelled, and you must either leave Thailand or apply for a different visa type.
