Migrants and refugees face hostile publics and organized political interests, and contend with new and evolving forms of surveillance, deportability, and political violence. Researchers show that these political dynamics are fundamentally shaped by the politics of race and ethnicity. Yet, even as this work is increasingly abundant, it has not always been taken up by mainstream accounts of migration. In this article, we revisit scholarship on the politics of international migration, bringing together a collection of — sometimes disparate — research to explore how scholars can forge new lines of inquiry regarding the relationship between migration, race, ethnicity, and power. To do so, we evaluate three types of relationships at the core of migration politics: the relationship between migration and the state, the migration-related demands of domestic publics on the state, and how migrants interact and contend with the state. Across these relationships, we examine how ethnoracial hierarchies draw on, legitimize, and reinforce uneven distributions of political power, disparate deployments of state action and violence, and projects of nation- and state-building. Combining the intellectual prowess of distinct fields and approaches, we draw on productive convergences and tensions between existing and emerging frameworks and analytic starting points across disciplines to map future research trajectories in the multidisciplinary study of immigration, citizenship, asylum, and racial and ethnic politics. We conclude with a note on the politics of knowledge production–whereby some accounts of migration have been privileged over others–and point to important epistemological and methodological interventions for advancing research on the politics of migration.
