Thailand Family Visa (2026)
Updated 21 July 2026 · Requirements vary by office — confirm before applying
The family visa is not one visa but several routes under the Non-Immigrant O category, each anchored to a different relationship. Getting the ground right at the outset is what determines the whole document package.
The grounds for a family visa
Applications are built on the relationship, so the first question is always which of these you actually fall under:
| Ground | Who it covers | Core documents |
|---|---|---|
| Spouse of a Thai national | Married to a Thai citizen | Passport, photo, marriage certificate, spouse's Thai ID, Tabien Baan, finances |
| Parent of a Thai child | Parent of a child holding Thai nationality | Passport, photo, child's birth certificate, child's Thai documents, finances, custody papers if relevant |
| Spouse of a foreigner | Married to a foreigner holding a Thai visa | Passport, photo, marriage certificate, principal's passport and visa, finances |
| Child of a foreigner | Child of a foreigner holding a Thai visa | Child's passport, photo, birth certificate, parent's passport and visa, finances |
Choosing the wrong ground is the most expensive mistake on a family case — it invalidates the document list you have already assembled. Confirm the relationship basis before collecting anything else.
Finances
There is no universal family-visa figure. What is required depends on the ground — spouse of a Thai national, parent of a Thai child, or dependant of a foreign visa holder — and on the office processing the case. Verify the applicable threshold and which documents count before you build the package around a number you found elsewhere.
Translation and legalisation
Foreign marriage and birth certificates generally require certified translation and legalisation before they can be used. This is routinely underestimated: it takes time, it is done outside the visa process, and an unlegalised certificate will stall an otherwise complete application. Start it early.
Common reasons family cases fail
- The wrong relationship ground was chosen at the outset
- Relationship documents are missing, uncertified or untranslated
- Financial evidence does not match what the specific office requires
- The principal visa holder's own status is not properly evidenced (for dependant routes)
- The applicant expects work rights that the visa does not grant
What a family visa does not do
It provides a basis to stay in Thailand on family grounds — nothing more. It is not a work permit, and it does not by itself confer permanent residency. Anyone intending to work needs the appropriate visa category plus a separate work permit.
Frequently asked questions
Who can apply for a Thailand family visa?
The main grounds are being the spouse of a Thai national, the parent of a Thai child, or the spouse or child of a foreigner who holds a valid Thai visa. Each ground has its own document set, and the relationship must be documented rather than merely asserted.
What documents prove the family relationship?
Typically a marriage certificate for a spouse, or a birth certificate for a child, alongside the passports of both parties. For Thai-national grounds you will also need the spouse or child's Thai ID and house registration (Tabien Baan); custody papers may be required where relevant.
How much money is required for a family visa?
There is no single figure — financial requirements depend on which ground you apply under and on the office handling the case. Confirm the specific threshold and acceptable evidence before assembling the package.
Does a family visa let me work in Thailand?
No. A family visa provides a basis to stay, not the right to work. Employment requires a separate work permit and the appropriate visa category.
Do documents need translation and legalisation?
Yes, in most cases. Foreign-issued certificates usually need certified translation and legalisation, and this step is one of the most common causes of delay — arrange it early rather than at submission.
