Step-by-Step Process

5. Final documents are scanned and emailed for your review before physical dispatch.

Rush turnaround: 1-3 business days (rush surcharge applies).
Government fees are charged at official rates with no markup.
Domestic EMS at Thailand Post rates; international DHL/FedEx at actual weight-based rates.

Common Pitfalls & How to Avoid Them

Originals out of validity window — many destinations require documents issued within 3-6 months. Confirm with the destination authority first.
Name mismatch between document and passport — embassies reject these. Correct it at the district office before translating.
Using a translator without an official seal — MFA and embassies will not accept it; you'll restart the chain.
Skipping MFA legalization before the embassy step — wastes multiple trips and weeks of time.
