As the first study to describe DACA-eligible young adults' health needs, these data demonstrate their profound mental health challenges and numerous barriers to health care access. Many barriers were attributed to their undocumented status and persisted even when they gained temporary legal status. This work provides a foundation for evidence-based policy changes to address the health needs of this and other undocumented populations.

Undocumented immigrant young adults growing up in the United States face significant challenges. For those qualified, the Deferred Action for Childhood Arrivals (DACA) program's protections may alleviate stressors, with implications for their mental health and wellbeing (MHWB). We conducted nine focus groups with 61 DACA-eligible Latinos (ages 18-31) in California to investigate their health needs. Participants reported MHWB as their greatest health concern and viewed DACA as beneficial through increasing access to opportunities and promoting belonging and peer support. Participants found that DACA also introduced unanticipated challenges, including greater adult responsibilities and a new precarious identity. Thus, immigration policies such as DACA may influence undocumented young adults' MHWB in expected and unexpected ways. Research into the impacts of policy changes on young immigrants' MHWB can guide stakeholders to better address this population's health needs. MHWB implications include the need to reduce fear of deportation and increase access to services.
