Q1111. How do I legalize foreign child birth certificates for Thai dependent visa applications?

Answered by the NYC Visa & Translation legalization desk

For a Thai dependent visa, start by asking the receiving Thai embassy or Immigration office which birth certificate format and authentication route it accepts. Obtain an official birth certificate showing the child’s parents, and check that names match the family’s passports. Ask the Thai embassy responsible for the issuing country whether authentication by that country’s authorities and Thai consular legalization are required. Arrange a Thai translation if requested, then submit the authenticated document and translation to Thailand’s Department of Consular Affairs when its legalization is required. A common pitfall is using a short-form certificate that omits parental details needed to prove dependency. Verify the required document chain with the receiving official authority before filing.
