This article reviews the field of citizenship studies, with attention to the causes and consequences of policy. It summarizes key findings and points of consensus across three research domains: the determinants of citizenship policy, the consequences of citizenship policy, and the consequences of citizenship, i.e., the utility of obtaining citizenship for immigrant integration. After identifying strengths and weaknesses of each, I propose new directions in research that widen the field in terms of cases and generalizable theory while also deepening the field through serious attention to approaches that center the immigrant experience.
