Korea Adoption Services’s “Searching for Adoptees” webpage is for birth families searching for their biological children. For adoptees searching for their birth families, there is an additional page called “Searching for Birth Family.” KAS offers post-adoption services, too. The posted story will be translated in Korean and get posted on a Family Search board of Korean webpage as well. This source can apply to and most benefit Korean adoptees or birth families who want to search for one another.
China Family Search is a resource page for those in the Chinese adoption community interested in birth family searching. It offers information and resources for both the adoptive parent and the adoptee. This source would be a good starting point for Chinese adoptees interested in searching and their parent.
