Who the Thailand Dependent Visa is designed for
A good fit
- You are the legally married spouse of someone holding a Thai work visa, retirement visa, education visa or similar long-stay status.
- You are a child under 20 of a foreign national with a valid Thai visa.
- You are a parent of a Thai national.
- You are the spouse or child of a Thai citizen (Non-O by marriage or by family).
Not for you if
- Your primary holder is on a tourist visa or visa exemption — dependant extensions are not granted against short-stay stamps.
- You want to work — you need your own work visa and work permit, not a dependent visa.
- Your relationship is not legally registered — cohabitation without a registered marriage does not qualify.
- The primary holder's visa has expired or been revoked — the dependent visa cannot exist without it.

How to apply
Route 1 — apply abroad alongside the primary holder
The cleanest route. Both the primary holder and the dependant apply at the same embassy at the same time, with cross-referenced documents.
- 01Gather relationship documentsMarriage certificate, birth certificates for children. All must be apostilled or legalised by the issuing country and translated. Allow 2 to 4 weeks.
- 02Apply at the same Thai Embassy as the primary holderSubmit the dependent application together with a copy of the primary holder's visa or application receipt. The consulate processes both in parallel.
- 03Enter Thailand togetherThe dependent visa stamp gives 90 days of stay, same as the primary holder. Enter within the visa validity period.
- 04Extend stay at ImmigrationBefore the 90-day stamp expires, apply for an extension at Immigration. Bring the primary holder's passport and latest extension stamp. The dependent extension is tied to the primary holder's.
Route 2 — the dependant joins later
If the primary holder is already in Thailand, the dependant applies at an embassy abroad using the primary holder's documents sent by mail or scanned.
- 01Primary holder sends documents from ThailandA notarised copy of the passport, visa stamp, extension, and work permit (if applicable). Some embassies accept scans; others require originals.
- 02Dependant applies at a Thai EmbassyWith the relationship documents and the primary holder's materials. Processing time: 5 to 15 working days.
- 03Enter Thailand and extend at ImmigrationThe same extension process as Route 1. The primary holder should accompany the dependant to Immigration.
Common mistakes and refusal reasons
1. Relationship documents not legalised
The most common cause of refusal. A marriage certificate or birth certificate issued in your home country must be apostilled or legalised, then translated by a certified translator. Photocopies and unofficial translations are not accepted.
2. Primary holder's status changes or lapses
If the primary holder loses their visa, changes status or does not extend, the dependent extension falls away. Both extensions must be tracked and renewed together.
3. Applying against a short-stay stamp
Tourist visa exemptions and short-stay stamps do not support dependent extensions. The primary holder must be on a Non-B, Non-O, Non-ED or similar long-stay visa.
4. Assuming work rights come with the visa
A dependent visa is a stay permit. Working on it — even for a foreign employer — is not authorised. You need a separate work permit and, in most cases, a change of status to Non-B.
Frequently asked questions
Can a dependant work in Thailand?
Not on the dependent visa alone. You need your own work permit and, usually, a change of status to a Non-B visa. The exception is LTR dependants, who can apply for a digital work permit directly.
What happens if we divorce while I am on a dependent visa?
The dependent visa is based on the marriage. If the marriage ends, the basis for the visa disappears. You would need to change to a different visa category or leave Thailand before the current stamp expires.
Can same-sex spouses apply?
Thailand's Marriage Equality Act took effect on 23 January 2025. Same-sex marriages registered in Thailand are recognised. Recognition of foreign same-sex marriages varies by consulate — check with the specific embassy.
My child is turning 20. What happens?
Dependent status for children ends at age 20. After that, the child must qualify for their own visa — education (Non-ED), work (Non-B), or another category.
Can both parents come as dependants of each other?
No. One person must be the primary holder with their own qualifying visa. The other can be a dependant. You cannot have a circular dependency.
