The Office of Refugee Resettlement (ORR) is a program of the Administration for Children and Families, an office within the United States Department of Health and Human Services, created with the passing of the United States Refugee Act of 1980 (Public Law 96-212).

The Office of Refugee Resettlement offers support for refugees seeking safe haven within the United States, including victims of human trafficking, those seeking asylum from persecution, survivors of torture and war, and unaccompanied alien children.

The mission and purpose of the Office of Refugee Resettlement is to assist in the relocation process and provide needed services to individuals granted asylum within the United States.

The largest share of that, $1.303 billion, was designated for the Unaccompanied Alien Children program housing child migrants.

[4] Before World War II, nonprofit voluntary agencies called "Volags" were generally responsible for aiding immigrants and refugees.

[6] In 2000, additional categories of potential recipients of ORR services were added including persons granted asylum, survivors of torture, unaccompanied alien children and certified adult victims of human trafficking.

The Unaccompanied Alien Children program was transferred to ORR by the Homeland Security Act of 2002, effective on March 1, 2003.

States provide transitional cash and medical assistance and social services, as well as maintain legal responsibility for the care of unaccompanied refugee children.

Within the Department of Health and Human Services the ORR partners with the Office for Civil Rights, the Center for Disease Control, the Office of Head Start, the Substance Abuse and Mental Health Services Administration, and the U.S. Administration on Aging.
