Approximately 27 percent of inmates in Federal BOP custody are non-U.S. citizens. ERO created the DEPORT Center in Chicago to process this population through CAP. ERO personnel assigned to the DEPORT Center conduct interviews of BOP inmates nationwide using video teleconference equipment. Through the combined effort of the DEPORT Center and local ERO resources, criminal aliens from all federal detention facilities are taken into ERO custody upon completion of their sentences.
