This bill, known as the Kayla Hamilton Act, significantly amends the William Wilberforce Trafficking Victims Protection Reauthorization Act of 2008 and the Homeland Security Act of 2002 to enhance efforts against child trafficking, particularly concerning unaccompanied alien children (UACs). It mandates more rigorous procedures for the Office of Refugee Resettlement (ORR) when making placement determinations for UACs, aiming to strengthen protections and ensure their safety. Before placing a UAC, the Secretary of Health and Human Services (HHS) must consult with the Department of Homeland Security and the Attorney General to assess factors such as flight risk, danger to self or others, and any criminal history, ensuring the child's protection from exploitation. For UACs aged 12 or older, HHS is required to contact their country's consulate for criminal records and examine them for gang-related tattoos or markings. The bill explicitly prohibits releasing UACs on their own recognizance, emphasizing secure custody. Furthermore, the legislation mandates that UACs aged 12 or older who are deemed a flight risk or a danger to the community —including those with gang affiliations, serious criminal convictions, or aggravated felonies—be placed in secure facilities throughout their immigration proceedings. It also establishes strict prohibitions on who can sponsor a UAC, disallowing placement with individuals who are not U.S. citizens or lawful permanent residents. Sponsors, and any adult household residents, are also disqualified if they have been convicted of a wide range of offenses, such as sex offenses, trafficking, domestic violence, child abuse, murder, or any felony. Before any placement, HHS must provide the Department of Homeland Security with comprehensive personal information and the results of thorough background checks for all adults in the prospective sponsor's household, including national criminal history and sex offender registry checks. These measures are designed to ensure safer placements and prevent UACs from falling victim to trafficking or other harmful activities.
