Intercountry adoption from Latin America became a sizable, “quiet” migration to the U.S., as evident in its historical evolution from El Salvador, Guatemala, and Honduras. The recent migration of unaccompanied minors and families traveling with children from these case countries has been characterized by child–family separation, prolonged detention and institutionalization of children, and adoption through various means. This study has been concerned with how both trends became intertwined in the era of globalisation. To address this question, the authors examined intercountry adoption literature and migration-related briefs, legal claims, and news reports. The study suggests that internationally recognized child rights have been violated in the border crisis. Forced family separation resulting from stricter immigration measures has met criteria for child abduction, violating international convention protecting families in transnational kinship and adoption. A child–family separation typology was inferred from individual case studies ranging from separation by death to prolonged or indefinitive separation to de facto adoption. Reunification has failed for migrant children in custody since relatives or kinship members may be undocumented or parents may be deported. The current immigration system for migrant children’s care only prolongs their detention and violates their human and civil rights while turning child abduction into de facto adoption.
