The study of modern human migration takes place across multiple disciplines and engages a wide variety of methodologies, and yet issues of gender and sexuality have largely been understood as marginal to this pivotal area of research. This essay highlights key contributions regarding migration by gender and sexuality scholars. First, research on women’s migration experiences has opened new historical understandings of national inclusion and exclusion. Second, critical, queer, and trans migration studies approaches have scrutinized normativity in ways that have produced new and generative questions regarding state-based rights and policies. Third, and relatedly, this critique has forced us to rethink such fundamental social concepts as citizenship, belonging, and borders.
