How do I legalise a Thai Thai national ID card for use in Saudi Arabia?

Under Department of Consular Affairs practice, Processing time: Standard legalisation 3–5 business days · Express 1–2 business days · Full chain (translation + MFA + destination embassy) 5–7 business days. The usual causes of delay are name spellings that do not match the passport, unclear seals, and copies older than the receiving authority allows — all of which we check before submission. Send scans to LINE @NAATI or contact@naati.ltd and our team will confirm the correct certification route before any work starts.
