Education Guardian Visa (O-Guardian)

The Non-Immigrant O guardian route explained

When a foreign child studies in Thailand on a Non-Immigrant ED visa, one accompanying parent may obtain a Non-Immigrant O visa as guardian, with extensions of stay granted by the Immigration Bureau under the Immigration Act B.E. 2522 (1979) and the Royal Thai Police order that sets the extension criteria. The guardian's permission to stay is derivative: it exists because the child's study permission exists, and it ends when the child's does.

Only one guardian is normally granted this status per child. A second parent typically needs an independent basis — their own employment, retirement, marriage to a Thai national, or a long-stay category — and families who assume both parents will be covered often discover this only weeks before a visa run.

Guardian status does not authorise work. A guardian who wishes to work needs a work permit and, in practice, a change of visa category, because the guardian extension is not a permitted basis for employment.

Documents Immigration expects at extension

Foreign birth certificates are the recurring failure point. They must be translated into Thai and carry the legalisation chain from the issuing country's authority through the Royal Thai Embassy; because Thailand's Apostille accession takes effect only on 28 February 2027, an apostille by itself will not be accepted before that date.

• The child's current ED visa or extension, plus the school's confirmation of enrolment and attendance for the current term.
• A letter from the school addressed to Immigration requesting the guardian extension and naming the guardian.
• The child's birth certificate showing the parental relationship, translated into Thai and legalised where issued abroad.
• Proof of funds: a Thai bank account in the guardian's name commonly showing at least 500,000 baht seasoned for the required period, per the applicable Immigration order.
• Proof of residence: TM.30 filed by the landlord or hotel, plus a lease or title document.
• TM.7 application form, photographs to specification, and the passport with a valid entry.

Choosing the right school route

Annual cycle and the mistakes families make

1. Two months before expiry: Request the school letter and enrolment confirmation; schools are slow in holiday periods.
2. Six weeks before: Ensure the bank balance has been seasoned continuously; a dip below the threshold during the seasoning window restarts it.
3. Thirty days before: File TM.7 at the Immigration office with jurisdiction over the registered address, together with the child's application if extended simultaneously.
4. Every ninety days: File the ninety-day report, and re-file TM.30 after any trip abroad or change of residence.

Common mistakes and how we avoid them

More questions we are asked

Can a grandparent be the guardian?

Immigration expects a parent. A grandparent or other relative needs documentary proof of legal guardianship, typically a court order, translated and legalised.

Does the guardian have to be in Thailand continuously?

No, but re-entry requires a re-entry permit or the extension is cancelled on departure.

What happens if the child changes school mid-year?

The child's ED status is re-issued through the new school and the guardian extension is re-documented against it; do not let a gap open between the two.

Can guardian status lead to permanent residence?

Guardian extensions do not by themselves build the qualifying record permanent residence applications rely on, which is usually based on work and tax history.

Is health insurance required?

Not as a universal condition of the guardian category, but individual offices and some school undertakings require it, so confirm locally before filing.
