Overview
Thai government handbooks describe different evidence for study extensions at government and private institutions. A generic list can miss approval or institution records that apply to a particular route.
Ask whether your institution is treated as government, private, international school, or higher education for the extension criterion.
Request a support letter that states study period, curriculum level, and relevant academic information.
Confirm whether establishment permission or a government agency confirmation is needed.
Contact the checkpoint in the area where you study for its current local procedure.
Compare
This comparison summarizes official handbook categories. The exact checklist can depend on the course, institution, and current Immigration instructions.
| Study setting | Published evidence framework | Ask your institution |
|---|---|---|
| Government education institution | TM.7, passport copy, and an institution letter requesting stay with education period, curriculum level, and academic information | Who issues the confirmation and what study records accompany it? |
| Private education institution | TM.7, institution operating permission evidence, institution request/confirmation, and in some cases relevant government confirmation | Which authorization records and authority letters apply to this school and course? |
| International school or higher education | Some government-confirmation requirements have stated exceptions; other documents still apply | Which exception applies, and what university or school documents must be submitted? |
Details
Ask for written guidance from your institution’s international office, then confirm the current submission checklist with the responsible checkpoint.
Do not infer the Immigration category from a school’s marketing description.
The official handbook expects education evidence that lets Immigration assess the requested stay.
Local checkpoints can provide the latest practical instructions for a complete application.
