International adoption involves crossing borders; it invokes space and geography as adoptive parents imagine distant countries, as children are moved from one nation to another, and as adoptees and their families return to their countries of origin. The spatiality of belonging and identity -but also of trauma and violence -are central concerns for the people involved and to the operations of their cultural, political, and legal practice. Yet surprisingly, cultural geographers have not yet developed a conceptualization of transnational adoption that theorizes it as a constitutive aspect of geographies of migration, domestic geographies, and geography of childhood. In this issue we seek to set out an agenda for the cultural and political geographies of transnational adoption. We do so by discussing three interrelated themes: the adoptionmigration nexus, geographies of relatedness, and the biopolitics of mobility.
