Direct answer
Thai family routes generally use a Non-Immigrant O purpose matched to the legal relationship and family member's status. ‘Marriage visa’ is informal shorthand: a spouse of a Thai national, parent of a Thai child, child joining a parent and dependant of a qualifying foreign holder may face different evidence and financial conditions. Short visits and long-term family residence should not be conflated.

Staying with family: routes and subtypes covered
Family visa routes for qualifying stays with Thai or non-Thai relatives and for certain diplomatic, labour and TECO dependants. The list below separates the current options that sit within this service family; the route code is NON-O. Each option still requires its own purpose, stage and filing-location check.
- Stay with non-Thai family residing in Thailand for more than 60 days — Financial evidence of at least THB 30,000
- Stay with Thai family residing in Thailand for more than 60 days — Evidence of monthly income of at least THB 40,000 or a current balance of at least THB 400,000
- Family or dependant of a diplomatic officer or official based in Thailand — Financial evidence of at least THB 30,000
- Child under 18 of a Non-Immigrant L-A holder — O(L-A) — The principal holder’s Non-Immigrant L-A visa
- Family or dependant of TECO personnel — A note verbale setting out the posting details
Which legal relationship records should support a family application?
Civil-status evidence should form an unbroken legal chain: marriage, birth, adoption, divorce, custody, name change and household or Thai identity records where relevant. The Thai or foreign sponsor's status, address, income or deposit evidence and shared-life facts must align with the chosen stage. Foreign records may need translation or legalisation.
Limits and decisions to check
A ceremony, cohabitation or relationship label is not always a legal marriage. Family status does not excuse overstay, unauthorised work or missing re-entry protection. Initial visas, in-country status changes and annual extensions can use different financial and procedural rules, and relationship changes must be disclosed.
TVC's practical assessment
Family evidence should show both legal status and practical reality without turning a private life into an unstructured photo album. We build a chronology, select documents that prove each legal element and use representative shared-life evidence only where relevant. More intimate material is not automatically better evidence.
