This policy statement, which recognizes the large changes in immigrant status since publication of the 2005 statement, "Providing Care for Immigrant, Homeless, and Migrant Children," focuses on strategies to support the health of immigrant children, infants, adolescents, and young adults. Homeless children will be addressed in a forthcoming separate statement ("Providing Care for Children and Adolescents Facing Homelessness and Housing Insecurity"). While recognizing the diversity across and within immigrant, migrant, and border populations, this statement provides a basic framework for serving and advocating for all immigrant children, with a particular focus on low-income and vulnerable populations.
