Protecting an Alien child's Reasonable Expectation of No Trafficking Act of 2023 or the PARENT Act of 2023 This bill establishes that no later than 72 hours after determining that a child in federal custody is an unaccompanied alien minor, custody of that child may only be transferred to the child's verified parent or legal guardian or to the Department of Health and Human Services (HHS). Currently, HHS may release such children to sponsors, who are not required to be a parent or legal guardian but must pass a background check.
