Foreign spouses of Thai nationals may obtain a Non-Immigrant O visa and extend it annually on the basis of marriage. Dependants of foreigners holding Non-B or other qualifying visas follow a parallel family route.
Immigration officers assess the genuineness of the relationship. Expect home-visit photographs, interviews and witness statements; preparation reduces delays considerably.
What we handle
- Marriage registration guidance (Kor Ror 2 / Kor Ror 3) and translations.
- Legalisation of foreign marriage certificates for use in Thailand.
- Relationship evidence and home-photograph preparation.

Counsel's note
A marriage registered abroad must be recorded at the Thai district office (Kor Ror 22) before it can support a Thai marriage-based extension in most offices.
