Why a Medical Certificate issued in Rayong needs MFA legalisation + embassy before Myanmar will accept it
A Medical Certificate produced by a Thai authority — whether the Amphoe Mueang office in Rayong, a Thai university, the Royal Thai Police, or a Bangkok commercial registrar — has no automatic extraterritorial effect. The receiving authority in Myanmar (immigration, university, court, civil registry, bank, or Embassy of Myanmar 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 Myanmar.
For clients in Rayong Province, NAATI Thailand removes every kilometre and queue: originals are couriered to our Lat Phrao office, drafted by a Sworn English Translator into English using the format Myanmar ministries prefer, notarised by a Lawyers Council attorney, then walked through MFA Chaeng Watthana — express track available — and forwarded to the Embassy of Myanmar, Bangkok (สาทร) for the second legalisation layer. The entire pipeline completes in 10-15 วันทำการ including return courier to Rayong or direct shipment to the receiving authority in Myanmar.

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

Common mistakes when sending from Rayong to Myanmar
- ใช้คำแปลที่ไม่มี Sworn stamp
- ลืม MOFA Naypyidaw สำหรับ property
- Skipping the Embassy of Myanmar, Bangkok (สาทร) 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 — Myanmar authorities verify against public registries.
