The Justice Department's Bureau of Prisons, fulfilling a presidential executive order requiring transparency on prisoner immigration status, said that it houses 187,855 inmates of which 42,034 are foreign born.
The DHS report said that only seven of those 42,034 have been granted deportation "relief." According to DHS:
19,749 (46.9 percent) are aliens who have received final orders of removal.
21,121 (50.2 percent) are aliens who are under ICE investigation for possible removal.
1,157 (2.8 percent) are aliens whose cases are pending adjudication before an Immigration Judge in the Executive Office of Immigration Review (EOIR).
7 (.0002 percent) are aliens who have been granted relief.
Homeland also said that the U.S. Marshal Service has a similar breakdown in its cells. Of 50,135 they've detained, 12,005 "self-report" as illegals. They are all in some type of deportation proceeding:
9,857 (82.1 percent) are aliens who have received final orders of removal.
2,047 (17.1 percent) are aliens whose cases are still pending adjudication before an immigration judge in the EOIR.
101 (.8 percent) are aliens still pending adjudication (U.S. Immigrations and Customs Enforcement has charged these aliens as removal cases, but a final disposition has not yet been reached.)
