How are specialized IT and digital competency certificates for foreigners authenticated?

Consular / Apostille

Practitioner's view to "How are specialized IT and digital competency certificates for foreigners authenticated?" — Thailand acceded to the Hague Apostille Convention on 14 February 2025, so documents destined for member states now need a single Apostille from MFA — no destination-embassy step, except for states that objected to Thailand's accession. You never need to attend Chaeng Watthana yourself — we file under a power of attorney, track the queue, and courier the sealed originals back by EMS or DHL worldwide.
