This article presents a critical review of the recent literature on undocumented students in higher education, placing it in the context of recent anti-immigrant sentiment and policy revisions. The 81 reviewed studies reveal that undocumented students confront significant financial barriers, shoulder unique psychological and social burdens tied to their legal status, and lack access to forms of social capital that facilitate postsecondary success. At the same time, they bring a host of assets to college campuses--including civic engagement and resilience--that are underutilized. Although their experiences are dependent on ethnoracial group and geographic context, these differences have not been sufficiently studied. Likewise, researchers have not adequately explored the impact of institutional, state, and federal programs designed to help undocumented students. In sum, the recent literature sheds some light on the experiences of undocumented postsecondary students, but further research should yield a more nuanced picture and better address their needs.
