Since the start of 2025, the federal office responsible for housing migrant children who arrive in the U.S. without a parent has passed along more than 460,000 pieces of information to immigration enforcement — details on the children themselves, the relatives trying to claim them, and other people living in those households. That's according to an internal-records review published July 28 by Reuters, which traces more than 12,000 arrests back to those referrals. The office at the center of it, the Office of Refugee Resettlement (ORR), sits inside the Department of Health and Human Services and exists to care for unaccompanied minors until a vetted sponsor — usually a parent or relative — can take them in.
