The Denver Field Office is one of the ICE Enforcement and Removal Operations (ERO) field offices that supervise detention and removal operations across the United States. This office oversees 3 detention facilities physically located in: CO, WY.
Each ICE ERO field office has a defined Area of Responsibility (AOR). ICE’s field-office directory (updated Sep 2, 2026) lists this office’s AOR as: Colorado, Wyoming. It lists the office at 12445 E. Caley Avenue, Centennial, CO 80111, phone (720) 873-2899. The same directory states that ICE’s field offices are not check-in locations; to find a check-in location, schedule or change an appointment, or update an address, ICE points to its ICE Check-in page. For further assistance after contacting the field office, ICE points to its ERO Contact Form or the ICE Detention and Reporting and Information Line, 1-888-351-4024. A non-citizen physically arrested in one AOR may be transferred to a detention facility in another AOR; ICE policy requires notice of transfer but does not require advance notice to family or attorneys.

How transfers between field offices work
ICE may transfer a detainee from a facility in one ERO field office’s AOR to a facility in another AOR for operational reasons (bed-space availability, medical needs, removal-flight staging). PBNDS 2011 standard 7.4 (Detainee Transfers) states that “[t]he legal representative-of-record shall be notified as soon as practicable, but no later than 24 hours after the detainee is transferred, in accordance with sound security practices.” That standard sets no deadline for updating the Online Detainee Locator System — it does not mention ODLS at all — and ICE publishes no ODLS refresh interval anywhere, so after a transfer a family should check locator.ice.gov repeatedly rather than treat one empty result as final. Family members are not notified directly.
Where cases from this office are heard
Immigration cases supervised by the Denver Field Office are heard at EOIR immigration courts in Colorado. EOIR’s administrative control list shows no immigration court seated in Wyoming, so cases from ICE facilities there are docketed to a court in another state — check the immigration court directory for the current assignment. The courts physically located in Colorado:
| Immigration court | State |
|---|---|
| Aurora Immigration Court | Colorado |
| Denver Immigration Court | Colorado |
Detained dockets move fast — hearings can be scheduled within weeks. Find judge-level hearing links on the immigration court pages.
