Expat relocation document service
This page sets out what expat relocation document service requires: 6 documents to prepare, 5 steps in the order they must actually happen, preparation advice, and the mistakes that most often send a file back. If you would rather not run the process yourself, our team can handle it end to end.

Documents to prepare
- Original document plus one clear copy of every page
- Copy of the passport or Thai national ID card of the signatory
- Written statement of the purpose and the receiving authority
- Supporting records the receiving authority lists in its own checklist
- Power of attorney if the signatory cannot attend in person
- Contact details for follow-up questions from the receiving authority
Process steps
- Step 1. State the purpose and the receiving authority so the correct level of certification is chosen.
- Step 2. Send scans of every page so completeness can be checked before work starts.
- Step 3. Prepare the translation or the instrument in the format the receiving authority requires.
- Step 4. Sign or certify before the officer authorised by law to witness that document type.
- Step 5. Collect the finished set and keep a copy for the next filing.

What gets files rejected
- Immigration offices differ in what supporting evidence they ask for locally.
- Address evidence must match the address written on the application form.
- Spell every name exactly as it appears in the passport, across every document in the same bundle.
- Never remove staples or separate pages that an authority has bound and stamped across the seam.
What this certified set is used for
- Long-stay visa extensions
- Family relocation to Thailand
- Local licence and account setup
An advisor, not only a document processor
Before any work starts, our team assesses how many certification layers your document actually needs, which authorities are involved, and the correct order for the office you will really file with. One step out of order usually means restarting the whole bundle. More than 15 years of cross-border document work means we recognise how each authority rejects files and prevent it up front.
- The certification route is matched to the receiving authority before work begins.
- Rejection risks are checked, from name spelling to document validity windows.
- The filing sequence is planned around the deadline you actually have.
