Attending school and securing lawful status in the United States are two keys to safety and security for undocumented unaccompanied homeless youth. This brief is designed to provide young people, immigration attorneys and advocates, McKinney-Vento liaisons and educators with basic information to help them access these keys. After describing some of the factors that cause youth to experience homelessness without a parent or guardian and the circumstances that result in immigrant youth being in the United States without their parents or guardians, the brief shares information about the federal laws that provide the means for youth to attend school and address their immigration status. A list of resources is included. (Contains 33 footnotes.) [This paper was produced with Kids in Need of Defense (KIND).]
