Office of Professional Responsibility (OPR)

The ICE Office of Professional Responsibility (OPR) upholds the agency’s standards for integrity and professionalism. As a key part of that responsibility, OPR investigates allegations of misconduct involving employees of ICE and U.S. Customs and Border Protection (CBP).

OPR investigates misconduct allegations based upon the following criteria:

  • Allegations that, if true, would constitute violations of state or federal criminal law; or
  • Allegations of misconduct that, if true, would jeopardize or undermine the agency’s ability to perform its mission.

In cases of potential misconduct, OPR prepares reports of its investigations for possible judicial or management action. OPR also provides independent reviews of ICE programs and offices, adjudicates ICE background investigations and issues security clearances for all prospective and current ICE employees and contract staff.

Finally, OPR oversees ICE detention functions, ensuring that facilities adhere to the agency’s detention standards. In the event of a detainee’s death, OPR investigates the circumstances of that death.


OPR is responsible for upholding DHS standards for integrity and professionalism by impartially investigating allegations of employee misconduct.

In addition, OPR inspects and reviews ICE offices, operations and processes in an effort to provide executive management with an independent review of the agency's organizational health. OPR oversees the agency’s detention functions to ensure compliance with ICE detention standards.
