Why a Medical Certificate issued in Nonthaburi needs MFA legalisation + embassy before Saudi Arabia will accept it
A Medical Certificate produced by a Thai authority — whether the Amphoe Mueang office in Nonthaburi, a Thai university, the Royal Thai Police, or a Bangkok commercial registrar — has no automatic extraterritorial effect. The receiving authority in Saudi Arabia (immigration, university, court, civil registry, bank, or Royal Embassy of Saudi Arabia 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 Saudi Arabia.
For clients in Nonthaburi Province, NAATI Thailand removes every kilometre and queue: originals are couriered to our Lat Phrao office, drafted by a MOJ Certified Arabic Translator into Arabic using the format Saudi Arabia ministries prefer, notarised by a Lawyers Council attorney, then walked through MFA Chaeng Watthana — express track available — and forwarded to the Royal Embassy of Saudi Arabia, Bangkok (สาทร) for the second legalisation layer. The entire pipeline completes in 18-28 วันทำการ including return courier to Nonthaburi or direct shipment to the receiving authority in Saudi Arabia.

- ใช้ translator ที่ไม่มี MOJ number
- Healthcare: ลืม DataFlow ก่อน
- Skipping the Royal Embassy of Saudi Arabia, Bangkok (สาทร) step — the destination authority will reject MFA-only files.
