Why a Passport issued in Songkhla needs MFA legalisation + embassy before Vietnam will accept it
A Passport produced by a Thai authority — whether the Amphoe Mueang office in Songkhla, a Thai university, the Royal Thai Police, or a Bangkok commercial registrar — has no automatic extraterritorial effect. The receiving authority in Vietnam (immigration, university, court, civil registry, bank, or Embassy of Vietnam counterpart) needs cryptographic-grade assurance that the Thai signature, seal and paper are genuine. That assurance is provided by the Thai Ministry of Foreign Affairs' Department of Consular Affairs at Chaeng Watthana through a full legalisation chain authorised under the bilateral consular convention with Vietnam.
For clients in Songkhla Province, NAATI Thailand removes every kilometre and queue: originals are couriered to our Lat Phrao office, drafted by a Certified Vietnamese (in VN) หรือ Sworn EN into Vietnamese หรือ English using the format Vietnam ministries prefer, notarised by a Lawyers Council attorney, then walked through MFA Chaeng Watthana — express track available — and forwarded to the Embassy of Vietnam, Bangkok (วิทยุ) for the second legalisation layer. The entire pipeline completes in 12-18 วันทำการ including return courier to Songkhla or direct shipment to the receiving authority in Vietnam.

Each scenario carries slightly different formatting expectations (page headers, signature placement, translation footer), which is why working with a translator who is registered for Vietnam authorities — not a generic agency — matters.

Common mistakes when sending from Songkhla to Vietnam
- แปลในไทยแล้วคิดว่าใช้ที่เวียดนามได้
- ไม่ผ่าน MFA TH ก่อน Vietnam Embassy
- Skipping the Embassy of Vietnam, Bangkok (วิทยุ) step — the destination authority will reject MFA-only files.
- Translating after MFA instead of before — the MFA stamp must cover the translation footer, not the source-language original alone.
- Using a freelance translator without an MoJ / Sworn registration — Vietnam authorities verify against public registries.
