Despite nearly half a million transnational adoptions to the United States, most of which are also transracial, sociological research has given little attention to this phenomenon. This review demonstrates why more sociological attention on Korean transnational adoption in particular is warranted. I review one area with overwhelming sociological significance—identity formation, including the distinct dimensions of racial, ethnic, and adoptive identities. While the bulk of this research has taken place outside of sociology, in reviewing the findings, I argue the sociological significance of Korean transnational transracial adoption to examinations of race, racialization, and identity formation.
