In this paper, I argue that, all else equal, immigrants who possess dual identities—that is, those who perceive attachment both to residents of their host country or region and residents of their home country—are, on net, more likely to engage in politics than those who lack such identities. I emphasize that immigrants’ notion that they are members of their host society—and hence deserving of the rights implied by their membership—provides the psychological basis for claims-making. Immigrants’ identification with those of the same national or ethnic origins, in turn, can facilitate perceptions of shared grievances—motivating political mobilization. Employing recently-released survey representative data from the Local multidem project and qualitative evidence from Switzerland, I present preliminary statistical evidence that dual identification bears positively on political participation among both naturalized and non-naturalized first-generation immigrants. My results hold both across a pooled multi-ethnic sample of immigrants in 10 European cities
