Authentication chain for Name/Surname Change Certificate bound for United States
United States is a member of the Hague Apostille Convention — therefore Name/Surname Change Certificate must pass through: Notary Public → MFA Thailand → Apostille (for United States).
Once the MFA issues an Apostille, United States accepts it directly — no further embassy step required, saving 1-2 weeks and embassy fees.
Our team refreshes United States requirements quarterly to avoid bounce-back on format changes.
