In this article, we argue that gender is relevant to the moral evaluation of migration policies concerning (a) immigrant admissions, (b) the status of migrants (documented and undocumented) in receiving countries, (c) refugee admissions, and (d) border enforcement and undocumented migration. We draw on existing feminist and other philosophical work to make the case that gender ought to be treated as a significant category of analysis by theorists writing on migration ethics in each of these four areas. We conclude by considering what policies gender justice requires in the area of international migration and propose several questions we believe philosophers are especially well equipped to address.
