This qualitative study explored the lived experiences of undocumented youth and the mental health impacts of living in daily fear of detention and deportation. In-depth, semi-structured interviews were conducted to examine the repercussions of living without immigration status, and the descriptive data were analyzed using a grounded theory approach. Results indicate that lack of immigration status is associated with mental health issues, particularly anxiety. Absence of immigration status is implicated as a decisive social factor influencing individuals’ mental and social well-being.
