Pearl did not like how adoption worked in America. The adoption companies in 1949 thought Asian children and children with mixed races were not able to be adopted. Pearl did not like that. Pearl created Welcome House, which was the first adoption company that had adoption internationally (between two different countries) and interracially (between races). However, some Asian kids were not able to be adopted. This led Pearl to create the Pearl S. Buck Foundation in 1964 to help those kids. It was later re-named Pearl S. Buck International. A year later she opened the Opportunity House (first called the Opportunity Center and Orphanage) in South Korea. Offices of the Opportunity House were later opened in Thailand, Vietnam, and the Philippines. She made Opportunity house to help Asian kids who were not able to live like other children.
