This article explores migration trauma among Mexican and Central American unaccompanied refugee minors (URM) with the purpose of developing an understanding of migration as a tripartite process consisting of: pre-migration exposure to traumatic stressors, in-journey stressors, and post-migration stressors. Social workers in schools are in unique positions to provide mental health services to URM. A case example illustrating a cultural adaptation of TF-CBT in an urban public high school is included.
