This article proposes that the role of cities in immigrant integration be reconsidered through the prism of urban citizenship, looking at how local policies co-regulate immigrants’ status, rights and identity. It argues that urban citizenship connects two dominant understandings of citizenship, as city governments are under pressure to reconcile the normative perspective of formal membership of the state with the claims for rights expressed by excluded parts of the urban citizenry. A case study of an inclusive way of regulating citizenship in Barcelona illustrates how a citizenship perspective can cast light on the specific ways in which cities regulate immigrant citizenship in interaction with higher levels of government, and highlights some of the levers cities possess to modify the boundaries between inclusion and exclusion of immigrants locally.
