Frequently asked questions about this case

How many steps does a certificate of origin (C/O) in Trang take before it can be used in Japan?

In practice, this type of file runs through 7 main steps, starting with "Establish how many layers of certification the Embassy of Japan or the receiving local authority requires and which channel the destination embassy accepts applications through." and ending with "Run a final checklist before handover and flag the follow-up risks if the receiving authority asks for further documents.". The receiving body is the Embassy of Japan or the receiving local authority, which checks both the content and the order of certification. Skipping a step usually means the file is returned and the process restarts.

Which documents do I need to prepare for this certificate of origin (C/O) case?

Prepare Requirements notice from the destination authority or embassy · Power of attorney with ID copies of both grantor and attorney · Original Freshly issued civil registry document · Original certificate of origin (C/O) before the first step. Names in English must match the passport spelling on every document, and a freshly issued copy is safer when the receiving authority sets a validity window.

How long does the process take?
