Non-Immigrant O — Spouse of a Thai National (initial, embassy-filed)วีซ่า Non-Immigrant O — คู่สมรสคนไทย (ครั้งแรก)

A 90-day single-entry Non-Immigrant O visa for the non-Thai spouse of a Thai national, filed at a Royal Thai Embassy/Consulate abroad (or via the e-Visa portal). It is the first step in the marriage route: obtain the Non-O abroad, enter Thailand, then apply for the in-country annual marriage extension in the last 30 days.

Duration

90 days, single entry. Typically converted to the one-year marriage extension in-country within the final 30 days.

Extensions

Convert to the one-year marriage extension (Order RTP 327/2557 § 2.18) in-country within the final 30 days of the Non-O.

Financial requirement

Posts typically request an original bank statement showing at least 400,000 THB (or equivalent) over recent months. The hard 400,000 THB / 40,000-THB-per-month test is enforced at the in-country extension stage (as of 2026-05-24).

Fees

Embassy fees are set in local currency per post. THB-equivalent is commonly ~2,000 THB single-entry / ~5,000 THB multiple-entry, but the exact figure varies by consulate — confirm with the specific post.

Processing time

Around 7 days; varies by post and by e-Visa vs in-person.

Who it’s for

• Foreigners legally married to a Thai national who are outside Thailand
• Spouses who want to enter on the correct visa to then convert to a one-year marriage extension
• Same-sex married couples (covered since the Marriage Equality Act, effective 23 January 2025)

Key documents

• Universal MFA visa application form + photo
• Passport (6+ months) + copies
• Original marriage certificate (with certified translation if foreign-issued)
• Thai spouse’s national ID card + house registration (Tabien Baan)
• Wedding / family photographs
• Applicant financial proof (~6-month bank statement)

Staying compliant

• This is just the entry visa — ongoing obligations (90-day reporting, marriage evidence) attach at the extension stage
• File the TM.30 address notification on arrival

Common pitfalls

• Foreign marriage certificate without certified translation / legalisation
• Missing Thai-spouse documents (ID + Tabien Baan) or thin relationship evidence
• Insufficient or late bank statement
• Treating the 90-day Non-O as the long-term solution — it must be converted to the marriage extension in-country
• Assuming a fixed THB fee; embassy fees are local-currency
