UACs ( Unaccompanied Alien Children) who cross into the United States over the international border with Mexico are normally transferred to the custody of the HHS Office of Refugee Resettlement (ORR), however a February 2023 report found that that the office lost track of over 85,000 such children after their placement in the care of U.S.-based sponsors

In 2022, HHS removed the requirement to collect documentation from potential sponsors that verify their immigration status or U.S. citizenship in the Family Reunification application. This is a clear failure that leaves migrant children vulnerable and provides criminals with an easy gateway into the United States
