U.S. Immigration and Customs Enforcement has hired a subsidiary of for-profit prison company GEO Group to aid in hunting down immigrants at their homes and places of work, according to records reviewed by The Intercept.

ICE has secured a deal with surveillance firm BI Incorporated as part of a new program, first reported in October by The Intercept, to use private bounty hunters to determine the locations of immigrants in exchange for monetary bonuses.

BI, which was acquired by the GEO Group in 2011, is one of several firms hired by ICE to provide “skip tracing” services, in which its teams of corporate investigators will use surveillance to track immigrants across the country to their homes and places of work so federal agents can easily swoop in and make arrests.

Records show ICE has already paid BI $1.6 million, with the potential for the contract to grow to as much as $121 million by the time it concludes in 2027.

ICE’s push to privatize its hunt for immigrants has drawn the scrutiny of Rep. Raja Krishnamoorthi, D-Ill., who warned it “invites the very abuses, secrecy, and corruption our founders sought to prevent.”

Neither BI Incorporated nor GEO Group immediately responded to a request for comment.

The deal illustrates a strategy of vertical integration within GEO Group, which has found a growing line of business operating for-profit immigration detention centers under the second Trump administration. In this case, the corporation stands to be paid by the federal government to both find immigrants and then to imprison them.
