ICE Cannot Effectively Monitor the Location and Status of All Unaccompanied Alien Children After Federal Custody

After meeting with more than 140 individuals from DHS and other Federal agencies, we determined U.S. Immigration and Customs Enforcement (ICE) cannot effectively monitor the location and status of all unaccompanied alien children (UACs) once released or transferred from Department of Homeland Security and U.S. Department of Health and Human Services’ (HHS) custody. From fiscal years 2019 to 2023, ICE transferred more than 448,000 UACs to HHS; most were released to sponsors. However, more than 31,000 of the 448,000 children’s release addresses were blank, undeliverable, or missing apartment numbers. ICE also was not always aware of the location for UACs who fled HHS’ custody.
