Undocumented college students, who often live off campus for financial reasons as well as family obligations, cannot take advantage of what is considered to be a primary factor in facilitating student success: the sense of community and of mattering that are provided by residence halls, residential staff, and thoughtful programming. In order to determine the perceptions that undocumented college students have of the on-campus experience, this study investigated two central issues: (1) the barriers to undocumented college students living on campus and (2) their perceptions of how living off campus impacts their feelings of marginality or mattering. Participants' stories highlighted feelings of marginality as a result of several significant challenges to living on campus, especially family expectations and travel logistics. Our findings can contribute to the scholarship and can inform student affairs practitioners in their efforts to increase undocumented college students' sense of mattering.
