Non-O Spousal Visa

Non-Immigrant O (Marriage / Spouse of Thai) Visa — the complete 2026 guide

The Non-Immigrant O visa for marriage to a Thai national is one of the most popular long-stay routes for foreigners with Thai families. It is issued under the same Non-O category as retirement, family-visit, and dependent visas, but its extension rules are specific to spouses of Thai citizens. Note the terminology: there is no separate 'marriage visa' as a formal category — the correct name is Non-Immigrant O (based on marriage). It is not to be confused with getting married in Thailand, which is a separate legal process at your local district office; see /marriage-visa for that.

The visa runs on a 90-day initial stamp obtained at a Thai embassy in your home country (or occasionally in Vientiane or Penang if you're already in Southeast Asia), followed by 1-year in-country extensions at Immigration. Financial requirements are strict: either 400,000 THB in a Thai bank account (in your name, seasoned for at least 2 months before extension, ideally continuously present through the year) OR 40,000 THB monthly income transferred into Thailand and evidenced by an embassy income letter or Thai bank statements. Failing to maintain either qualifier will refuse your annual extension. The spousal visa does NOT include work authorisation — if you want to work, you need a separate Non-B and work permit.

Extension procedures involve an Immigration officer visiting your registered marital home to verify you actually live with your Thai spouse. Photos of your home, joint utility bills, and neighbours' witness statements are typical. This home-visit rule catches out sham marriages routinely. You also do 90-day reporting like other long-stay visas. Renewal requires updated marriage certificate, house registration (Tabien Baan) showing you're registered at the shared address, financial evidence, and spouse-attendance at Immigration. Cross-link to /marriage-visa for the wedding-registration process, /retirement for the alternative Non-O path via age 50+, and /embassies for embassy income letter procedures.

Application process, step by step

1. 1

   Register your marriage at a Thai district office

   If you married outside Thailand, first register the foreign marriage certificate through a Thai embassy and the Thai Ministry of Foreign Affairs. If getting married in Thailand, both parties present their passport, Thai ID (spouse), and a certificate of freedom to marry from your embassy at any Amphoe (district office). Certificate issued same-day. See /marriage-visa for details.

2. 2

   Choose your financial qualifier

   The 400,000 THB bank deposit route is more common. Deposit the money in a Thai bank account in your name at least 2 months before your extension appointment (Bangkok Bank, Kasikorn, and SCB are standard). The 40,000 THB monthly income route requires an income affidavit from your embassy (US, UK, Aus, Canada) OR verified salary transfers into a Thai bank account over the 12 months prior.

3. 3

   Get the initial 90-day Non-O visa

   Apply at a Thai embassy in your home country or a regional embassy. Present the marriage certificate, passport, spouse's Thai ID copy, house registration, financial evidence, and application form. Cost 2,000 THB single-entry. Alternatively, you can convert from a tourist visa to Non-O in-country at Chaeng Wattana if you're already in Thailand — bring the same documents plus 2,000 THB.

4. 4

   Book the 1-year extension appointment

   Within 30 days before your 90-day stamp expires, book at Chaeng Wattana or your provincial Immigration office. Your Thai spouse must attend with you. Bring the full document set: marriage certificate original + copies, spouse's ID and house registration, financial evidence (bank statements 12 months if using 400k route), TM.7 form, photos, 1,900 THB.

5. 5

   Undergo the home visit

   An Immigration officer visits your registered marital home within 30 days of your extension application, unannounced but during business hours. Have joint photos, utility bills in your name, and clothes/personal items obviously belonging to both of you. Neighbours may be asked to confirm you actually live there. Sham-marriage cases fail here.

6. 6

   Do 90-day reporting throughout the year

   Like all long-stay visas, Non-O holders must file a 90-day report at Immigration or online at tm47.immigration.go.th. Miss a report and you're fined 2,000 THB per infraction. Set calendar reminders for each 90-day anniversary. This obligation continues until you either upgrade to Permanent Residency or leave permanently.
