Which authority decides a Non-Immigrant ED student visa — Jurisdiction is split: visa issuance sits with Thai missions abroad, extensions and reporting with the Immigration Bureau, work authorisation with the Department of Employment, and investment privileges with the BOI. Holders staying beyond 90 days must file the 90-day report with Immigration, which is a separate obligation from extending the visa. A re-entry permit must be obtained before leaving Thailand in order to preserve an existing permission to stay. Extensions of stay and changes of visa class are decided by the Immigration Bureau under the Immigration Act B.E. 2522. Civil-registry records issued before computerisation may need a fresh extract taken from the register held by the district office. The receiving body may ask for extra proof of relationship, such as a birth certificate or house registration, where surnames differ. Where a travel date or court deadline applies, start early to absorb the hand-offs between agencies. Passport copies filed in support should show an unexpired page with the passport number clearly legible. Before work starts we confirm which version, which language and how many certification layers the receiving office expects, so nothing has to be redone.
“Which authority decides a Non-Immigrant ED student visa?” falls within an end-to-end service that combines document preparation, translation, signature certification, consular legalisation and coordination with the destination mission into a single file. The people who search for it are usually preparing a filing against a fixed deadline, recovering from a rejected submission and trying to identify the missed step, or coordinating documents for several people at once.
In practice, each step sits with a different body: the issuing office, the Notarial Services Attorney, the Department of Consular Affairs, and the destination country’s diplomatic mission. Knowing which body owns which step makes it possible to judge how many stages a bundle needs, and which of them cannot be corrected without starting again.
This is a baseline set. Individual receiving authorities may add requirements, so confirm with the destination body first.
Record how many stages each document needs, who certifies it, and what must finish first, so no step has to be redone.
Check personal names, company names, addresses and dates across the whole bundle before any certification begins.
Original → translation → signature certification / legalisation → destination mission. Doing these out of order forces a restart.
Verify the number of sets, the seals, the binding, and that issue dates are still within the destination’s validity window.
| Route | When it applies |
|---|---|
| Notarial Services Attorney certification | For privately drafted instruments — powers of attorney, affidavits, consent letters — signed in the attorney’s presence. |
| Legalisation at the Department of Consular Affairs | Where a foreign authority needs confirmation of the Thai issuing office’s signature and seal, or of the translation. |
| Attestation at the destination mission | Where the destination country requires its embassy or consulate in Thailand to attest the file after consular legalisation. |
| Thailand’s Apostille status | Thailand acceded to the Apostille Convention on 30 June 2026 and it enters into force for Thailand on 28 February 2027. No Apostille is issued in Thailand before that date. |
If you are working through “Which authority decides a Non-Immigrant ED student visa?”, start by getting the receiving authority’s requirement in writing, then plan the certification chain backwards from your real filing date.
