Abstract
In 2014, the United States saw a greater than 50% increase in the number of unaccompanied children from Mexico and Central America arriving at the U.S./Mexico border, and unaccompanied children continue to migrate to the United States in consistent numbers. The dramatic increase of 2014 exposed gaps in policies aimed at supporting unaccompanied children as they await legal adjudication. This paper begins with a historic review of immigration policies in the United States aimed at supporting unaccompanied migrant children. An analytic review is provided of existing immigration policies in the Department of Homeland Security and the Office of Refugee Resettlement, highlighting the competing paradigms created by missions of security‐focused policy versus child‐centred policy. A close examination of the values that influenced policy development in this area is included, along with a discussion of how social work practice can infuse elements of social justice into immigration policy reform. Areas for future research to reform immigration policy focused on supporting unaccompanied undocumented minors are highlighted.
