Birth Certificate Apostille for Thailand

Korean birth certificates for use in Thailand require embassy legalization, as Thailand is not a Hague Convention member. The document must be authenticated by MOFA, then legalized by the Thai Embassy in Seoul, and accompanied by a certified Thai translation. Common uses include marriage registration at a Thai Amphur (district office), retirement and LTR visa applications, and civil registration in Thailand.
