This study examines the experience of children who are unaccompanied immigrants and their families living in the Chicago metropolitan area from the perspective of the legal and human service professionals that accompany them. The government and community-based response to these young people are examined in context of child welfare principles that promote the best interest of the child. Findings suggest that children, irrespective of the system with which they are involved, would benefit from the application of the foundational principles of the best interest of the child, safety, well-being, and permanency.
