To whom must all individuals under the age of 18 be referred?

Individuals under the age of 18 who are encountered during immigration enforcement processes must be referred to the Office of Refugee Resettlement (ORR). This is primarily due to the agency's responsibility for the care and custody of unaccompanied minors who are apprehended by immigration authorities. The ORR ensures that these minors receive the necessary support, protection, and legal services, including family reunification when appropriate.

The other agencies listed do not have the same mandate related to the welfare of unaccompanied minors. The Department of Health Services typically deals with public health issues and may not focus specifically on immigrant minors. Customs and Border Protection (CBP) is responsible for enforcement and border security, but it does not provide the services designed for the needs of minors, nor does it have the long-term custody roles required. The National Child Welfare Council, while involved with child welfare, does not specifically address the immigration status or care of minors in the context of unaccompanied immigration cases. Thus, the ORR is the correct referral point in these situations to ensure the best interests of the child.
