The Hagåtña Detention Facility, run by the Guam Department of Corrections (GDOC), is the sole ICE-used detention site in the U.S. territory of Guam. It is a roughly 130-bed jail at 203 Aspinall Avenue, Hagåtña, that holds local pre-trial detainees, U.S. Marshals Service federal detainees, and ICE immigration detainees together. (GDOC’s main prison complex is in Mangilao; Hagåtña is the downtown detention annex.)

ICE Use and Contract Structure

• Custodial authority: U.S. Immigration and Customs Enforcement (DHS)
• Day-to-day management / contract: U.S. Marshals Service Inter-Governmental Agreement (IGA); ICE detainees are held under the USMS arrangement with GDOC rather than a standalone ICE IGSA
• ICE Field Office: San Francisco (Guam falls under the SF Area of Responsibility)
• Detainee population: adult men (adult women historically held in 2022)
• 2026 average daily population (immigration): ~15
• 2026 average length of stay: ~36 days
• Inspection: rated “Meets Standards” / “Acceptable” in documented 2024 and 2009 reviews (per Global Detention Project)

This is a low-volume site by mainland standards — historical immigration ADP has ranged roughly 7–33 (2007–2022), with documented gaps where migrant detention ceased (around 2013) before resuming. As of 2026 it appears in ICE’s list of active detention facilities and was named among the jurisdictions (all 50 states plus Guam, CNMI, Puerto Rico, and Guantánamo) where ICE detained people in February 2026.

Why It Matters

• Only ICE detention bed inventory in Guam. Anyone ICE detains in the Marianas region is held here (or in the CNMI), then typically removed via Honolulu. There is no dedicated ICE processing center in the territory.
• COFA-migrant pipeline. The detainee population is shaped by Guam’s unique status: Compact of Free Association (COFA) citizens from the Federated States of Micronesia (especially Chuuk), the Marshall Islands, and Palau live and work in Guam visa-free. They are removable if convicted of deportable/aggravated felonies, and Guam AG Douglas Moylan has explicitly targeted Chuukese/FSM nationals for removal (see note and county-fight entries).
• Conditions crisis (Dec 2025–Jan 2026). Lawmakers and AG Moylan described the facility as having broken HVAC, overcrowding, and inmates housed in dome tents — calling conditions “inhumane and dangerous.” Federal authorities removed roughly 20 federal detainees from the Hagåtña facility amid the deterioration, with warnings of lost USMS revenue and possible federal court intervention. This directly affects ICE/USMS bed availability in the territory.
