The Thai Marriage Visa — formally the Non-Immigrant O visa based on marriage to a Thai national — is how thousands of expat couples live together legally in Phuket. It's one of the more straightforward long-stay visa paths, but there are a few traps that trip up even long-term residents. This guide covers the full process from a Phuket-specific perspective.

Thai Marriage Visa Requirements 2026
1. Legal Marriage to a Thai National
You must be legally married to a Thai citizen. This means registered at a Thai district office (Amphur) and holding a Thai marriage certificate (Kor Ror 3). A Buddhist ceremony, Western ceremony, or religious blessing alone does not qualify. If you married abroad, you need a translated and legalised version of your foreign marriage certificate.
2. Financial Requirement
The financial requirement is lower than the retirement visa but still significant:
| Method | Amount | Notes |
|---|---|---|
| Bank deposit | ฿400,000 in Thai bank | Seasoned 2–3 months minimum |
| Monthly income | ฿40,000/month | Embassy income certificate required |
| Combination | Income + deposit = ฿400k/year | Income cert + passbook both needed |
3. Spouse Must Be Present (for Some Steps)
Your Thai spouse must typically accompany you to Phuket Immigration for the annual extension — or provide a signed declaration and ID copies if they cannot attend. Some immigration officers in Phuket require spouse presence; others don't. Bring your spouse if possible to avoid being sent away.
Phuket Immigration officers sometimes conduct spot checks on marriage visa holders to verify the relationship is genuine. They may visit your home address or ask detailed questions about your spouse. Couples with very large age gaps or where the foreign partner has limited Thai language sometimes face more scrutiny. This is standard practice and not cause for alarm if your marriage is genuine.
Document Checklist for Annual Extension
| Document | Notes |
|---|---|
| Passport (original + copies) | All pages with stamps, current visa/extension page |
| TM.7 application form | Available at Immigration or download in advance |
| 4×6cm photo | Recent, plain background |
| Thai marriage certificate (Kor Ror 3) | Original + copy; translated version if married abroad |
| Thai spouse's ID card (Baan Nai) | Original + copy |
| Thai spouse's house registration (Tabien Baan) | Original + copy |
| Bank passbook (original + copy) | 3-month balance history above ฿400k |
| Bank letter | From Thai bank, dated within 7 days of application |
| Photos of couple together | 6–12 photos showing couple in daily life — recommended |

| ฿1,900 cash | Extension fee — cards not accepted |
Bring a printed folder of 8–12 recent photos of you and your spouse together — at home, out dining in Rawai or Phuket Town, at family events. Immigration may not ask for them, but having them ready demonstrates the relationship is genuine and can smooth the process if questions arise.
How to Apply: Step by Step
Obtain your initial Non-O visa abroad
If you're not already in Thailand on a qualifying visa, apply for a Non-Immigrant O visa at a Thai embassy or consulate in your home country, specifying "marriage" as the purpose. You'll need the marriage certificate, spouse's Thai ID copy, and basic financial evidence.
Enter Thailand and register your address (TM30)
Your landlord (or your spouse, if living in their property) must file a TM30 notification within 24 hours of your arrival. Without this, your Immigration visit may not proceed smoothly.
Open a Thai bank account and season ฿400,000
Deposit ฿400,000+ into your Thai bank account at least 2–3 months before your extension application. KBank Yaowarat Road in Phuket Town is well-acquainted with expat immigration requirements. See our bank account guide.
Visit Phuket Immigration with your spouse
Apply 30–45 days before your current permission to stay expires. Bring the full document set above. Phuket Immigration on Phuket-Phang Nga Highway — arrive by 08:00 for a shorter wait. Extensions are usually processed same day.
Do 90-day reporting
Every 90 days, report your address to Phuket Immigration (in person, online via e-Services, or by post). See our 90-day reporting guide.
Get a re-entry permit before any international travel
Same as the retirement visa — if you leave Thailand without a re-entry permit (฿1,000 single / ฿3,800 multiple), your extension is cancelled. Apply at Phuket Immigration or the airport desk.
Can I Work on a Thai Marriage Visa?
The marriage visa itself does not permit employment. To work legally in Thailand on a marriage visa, you need to apply for a work permit separately — which requires an employer or your own Thai-registered company to sponsor you. The process involves the Ministry of Labour and requires your marriage visa as supporting documentation. See our work permit guide for the full process.
Many expats in Phuket run online businesses or work remotely for overseas clients while on a marriage visa. This technically falls in a grey area — remote work for a foreign employer without a Thai work permit is common practice but not formally legal. The DTV visa is a more appropriate option for digital nomads under 50.
Marriage Visa vs Other Phuket Long-Stay Options
| Visa | Eligibility | Bank Req. | Annual Cost | Work? |
|---|---|---|---|---|
| Marriage Visa (Non-O) | Married to Thai national | ฿400k | ฿1,900 | With work permit |
| Retirement Visa (Non-OA) | Age 50+ | ฿800k | ฿1,900 + insurance | No |
| Thailand Elite | Anyone | None | ฿10,000 + membership | No |
| DTV Nomad | Remote workers | ฿500k savings | ฿10,000 (5yr) | Remote only |
The marriage visa compares favourably: lower bank requirement than the retirement visa, no insurance mandate, and no age restriction. The main limitation is obvious — you must be married to a Thai citizen. See our complete Phuket visa guide for all options.
