ICE offices and areas of responsibility

We provide data on ICE field offices and their areas of responsibility (AOR) principally derived from ICE’s web site for use in conjunction with individual-level ICE data:

• ICE Enforcement and Removal Operations (ERO) field offices: The offices with primary responsibility for the majority of ICE arrests and its detentions and removals of noncitizens. Each field office has a defined geographic area of responsibility.
• ICE ERO check-in offices (sub-offices): The offices where noncitizens may be required to report periodically. These are sometimes known as the sub-offices of the main ICE ERO field offices.
• ICE areas of responsibility (AORs): Geographic region managed by each ICE ERO field office. The areas of responsibility for other sub-agencies, such as Homeland Security Investigations, differ. The AOR map was originally created by the University of Washington Center for Human Rights.

Below is a map and a table of the data, as well as download links in multiple formats.
