The oppressive legislative policies and polarizing media narratives of undocu/DACAmented Latinx im/migrants in the United States have created unfavorable campus climates, which have further marginalized those students in higher education who fit into this category. As a result of Donald Trump’s presidency and rescission of the Deferred Action for Childhood Arrivals (DACA) program that soon followed, undocu/DACAmented Latinx students are experiencing an increase in stress, anxiety, and fear to the point that they become silent, depressed, and feel the need to advocate more for their existence and worth on campus. My critical ethnographic case study investigates the everyday experiences of Mexican undocu/DACAmented students enrolled at a public university in Arizona – a state that borders Mexico – as they pursue their undergraduate degrees in the Trump era. This study is guided by critical race theory and LatCrit, sense of belonging, and resistance capital theoretical frameworks, and seeks to answer the following: (a) how race and racism shape their collegiate experiences, (b) where these collegians find belongingness to persist towards graduation while navigating an anti-im/migrant sociopolitical climate, and (c) how these students exercise agency via their activism efforts. The broader case study includes individual collaborative interviews, twelve months of participatory field observations, and a collection of documents. This study aims to expand the field of higher education’s understanding of how federal, state, and institutional policies and policymakers affect undocu/DACAmented students’ experiences in and persistence through college, highlight the agency exercised and assets these collegians bring with them to college, and offer research, policy, and practical recommendations for higher education and student affairs institutional agents.
