Non-Immigrant O: Marriage to a Thai National
This is the standard route for foreigners married to a Thai citizen. You enter on a 90-day Non-O visa, then extend it to one year at a time from inside Thailand. The whole game is timing and paperwork.
Who this is for
Foreign nationals legally married to a Thai citizen who want to live in Thailand long term. You apply for the initial 90-day visa from outside Thailand, then handle everything else after you arrive.
Step 1: Get the 90-day Non-O visa (from home)
Apply online only at thaievisa.go.th. There is no walk-in option at US posts anymore.
Timing matters
- The Royal Thai Embassy in Washington D.C. says: apply at least 30 days before departure, and not more than 90 days before. The visa is typically valid 90 days from issuance, so applying too early means it can expire before you travel, and you pay the fee again.
- The LA consulate says at least 15 working days. Follow the guidance of the post that will process your application.
- Processing at D.C. is currently running longer than usual because of high volume. Build in buffer.

Document checklist (e-Visa application)
Upload large, clear JPEG or PDF files, max 3 MB each. Unclear scans are the number one cause of delays. Tick items off as you gather them; your progress is saved on this device.
- Passport biodata page Passport valid at least 6 months beyond your travel date.
- Photograph taken within the last 6 months Passport-style, plain background.
- Proof of current location Driver's license, bank statement, or other proof you live where you say you do.
- Financial evidence D.C. post: bank statements for the last 3 months, each showing an ending balance of at least $15,000 in your name, OR proof of monthly income of at least $1,500 plus a current statement showing the deposits. The MFA checklist states the same requirement as 40,000 THB/month income or a 400,000 THB balance. Meet the version your processing post asks for.
- Spouse's Thai ID card or Thai passport A clear copy of your wife or husband's Thai national ID or passport.
- Marriage certificate Copy of the certificate proving the marriage. If it was issued outside Thailand or the US, you may need a certified English translation.

Step 2: Enter Thailand and start the clock
You receive up to 90 days of stay stamped in your passport on arrival. Everything below happens inside that window.
- Week 1: open a Thai bank account in your sole name. Bring your passport and marriage certificate. Some branches ask for a letter from immigration or your embassy; your Thai spouse coming along smooths this enormously. The account must be in your name only.
- Same week: move 400,000 THB into that account. This starts the seasoning clock. For the first one-year extension, the money must sit in the account for 2 full months before you apply.
- Well before day 90: apply for the one-year extension based on marriage at the immigration office for your province. Do not cut it close; go several weeks early.
Step 3: The one-year extension (in Thailand)
Typical documents immigration offices ask for on a marriage extension:
- TM7 application form (ตม.7) Available at the immigration office.
- Passport plus copies of every page Bring the originals and the copies.
- Bank letter and statements A letter from your Thai bank dated the day you apply, plus statements showing the 400,000 THB seasoned for 2 months. Some offices want the bank book updated the same day.
- Marriage certificate and Kor Ror 2 The Kor Ror 2 is the Thai marriage registry extract, obtained at the district office (amphur). It must be recent.
- Spouse's Thai ID and house registration (tabien baan) Copies, with your spouse present or a signed copy.
- Photos of you as a couple at home Offices commonly ask for photos of the two of you inside and outside your residence, plus a hand-drawn map to the house.
- Fee: 1,900 THB Standard extension-of-stay fee. Verify locally.
After approval you hold a one-year extension. You renew it the same way each year. For renewals the seasoning requirement is commonly 3 months rather than 2; confirm with your office.
Step 4: Living on the extension
- 90-day reporting (TM47, ตม.47): report your address every 90 days. In person, online, or by mail. See After arrival.
- Re-entry permits: if you leave Thailand without one, your extension is cancelled on departure and you start over. Get the permit before you fly.
- Keep the 400,000 THB in place. Letting the balance drop below the threshold can cause problems at renewal.
Common pitfalls
- Applying for the e-Visa too early. More than 90 days before travel risks the visa expiring before you fly. Another $80, another wait.
- Blurry uploads. The embassy specifically warns that unclear documents trigger requests and delays.
- Money in the wrong account. The 400,000 THB must be in a Thai bank account in the applicant's sole name, seasoned for the full period. A joint account or a foreign account does not count.
- Cutting the 90 days close. If anything goes wrong with the bank or the paperwork, you need buffer. Start the extension process weeks before the stamp expires.
- Forgetting the re-entry permit. One forgotten permit wipes out the extension. Make it a habit: permit first, tickets second.
- Assuming every office is the same. Document lists vary by province and even by officer. When in doubt, visit your office early and ask for their list.
