Although the notion of national citizenship has long held the promise of equal membership, it has proved less useful in a world of circulating cultures, people, and loyalties through money, media, and migration. The increasing mobility of capital and people across national borders compels us to conceptualize welfare and inequality at the global level. Although the enforcement of citizen rights remains within the purview of the nation‐state, the source of these rights can no longer be firmly placed within the national framework. From cosmopolitan imaginations to postnational research, contemporary configurations of citizenship trace their legitimacy to global discourses that increasingly challenge the national order of citizenship. Yet current transformations in citizenship also point to the possibility of new inequalities, particularly, when nation‐states are increasingly able to modulate the rights they make available to immigrants, and differentiate among refugees, professionals, and investors among many other categories of people.
