Authentication chain for Certificate of Tax Residency bound for Thailand
Thailand is not (yet) a Hague Apostille member — therefore Certificate of Tax Residency must pass through: Notary Public → MFA Thailand → Thailand Embassy.
After MFA Thailand, the Thailand Embassy in Bangkok must add their consular stamp before the document is usable abroad.
Note: Uses the consular legalization chain via MFA Thailand before the destination embassy
