Embassy attestation — what to prepare and the order that matters
Embassy legalisation is the final link of the outbound chain. An embassy will only act on a document that already carries Thai Department of Consular Affairs certification.
Documents to prepare
- Documents already legalised by the Department of Consular Affairs
- Translation in the language the embassy requires (some accept only their listed translators)
- Passports of the applicant and everyone named in the documents
- Embassy-specific forms and the online appointment slip where applicable
- Purpose evidence such as an admission letter, employment contract or invitation
- Copies of every document in the quantity the embassy specifies
Step-by-step procedure
1. Check that embassy's own rules
Requirements differ widely; read the embassy's current notice directly.
2. Assemble the set in order
Original, translation and consular seal must stay bound together.
3. Book and submit
Use the embassy's appointment system and file on the assigned slot.
4. Track and collect
Turnaround varies significantly by mission; build in buffer before your deadline.
Pitfalls to avoid
- A translator accepted by one embassy is not automatically accepted by another.
- Filing at the embassy before consular legalisation results in immediate refusal.
- Some missions accept only documents issued within a defined recency window.
- Never assume one country's procedure substitutes for another's.
Advisory tips
- Order multiple documents exactly as the embassy lists them.
- Keep every receipt and collection slip until the case closes.
- Ask in advance how many wet-ink sets the destination needs.
