Foreign documents used for a Thai work permit — the certification order, translation, and why files get returned
Quick answer
A document issued abroad becomes usable in Thailand only after it is certified under the issuing country’s own system and then further certified by the Thai embassy or consulate there, or through the route the Department of Consular Affairs specifies, before being translated into Thai or English with a certification. The order cannot be reversed, and the operative conditions are set by the receiving office, so confirm them before starting.
Key facts and the responsible authority
| Certification order | Certified in the issuing country → certified by the Thai embassy/consulate or the route Consular Affairs specifies → translated with a certification |
|---|---|
| Apostille status | Treaty status and any entry-into-force date for Thailand can change; check the HCCH status table and Consular Affairs announcements before planning documents |
| Translation language | Usually Thai or English as the receiving office directs; ask before ordering the translation |
| Document age | Police clearance and status documents are commonly required to have been issued recently within a stated window — confirm the window in force |
| Qualification verification | In some cases the authority asks the issuing institution to verify the qualification directly, which adds time — start early |
Document checklist and the certification involved
Degree certificate and academic transcript
Certified under the issuing country’s system, then translated with a certification
Employment reference from a previous employer
Should state the role, dates and scope consistent with the application
Police clearance certificate, where required
Issued by the relevant national police authority and certified in order before translation
Passport and the relevant stamped pages
Copies must be legible and cover every page the office lists
Step by step
- Ask the receiving office for its document list first: Request the list in writing from the employment office where you will file, or from HR staff who have filed at the same office.
- Complete certification in the issuing country: Use that country’s own system — typically its official document-certification authority — before moving to the Thai steps.
- Certify through the Thai channel: File for certification at the Thai embassy/consulate or by the route Consular Affairs has announced at that time.
- Translate with a certification and check name spellings: The translation must reproduce every stamp and note, and all names must match the passport exactly.
What to do
- Start with the longest-lead item, usually a foreign police clearance certificate.
- Keep high-resolution scans of every certified document for checking and for later filings.
- If the awarding institution has been renamed or merged, attach evidence of the change with the file.
What to avoid
- Do not translate before certifying — a translation made earlier will not cover stamps added afterwards.
- Copies self-certified by the holder are commonly refused.
- Never change a spelling in a translation; an error in the source must be corrected at the issuing office.
