Stop Human Trafficking of Unaccompanied Migrant Children Act of 2023

This bill requires stricter background checks and monitoring for sponsors caring for unaccompanied migrant children. It mandates fingerprint checks, sex offender registry reviews, criminal history checks, and child abuse screenings for all adult household members before a child can be placed with them. The bill also prohibits placing children with undocumented sponsors (except biological parents or legal guardians), requires pre-release home visits, and mandates multiple unannounced post-release visits over two years. Additionally, it requires monthly reports to Congress tracking child placements, vetting status, and missing children cases since January 2021. These changes directly affect unaccompanied migrant children and their sponsors, aiming to prevent trafficking through enhanced safety protocols.
