Guantanamo Migrant Operations Center

The Guantanamo Migrant Operations Center (GMOC) is a migrant detention facility at Guantanamo Bay detention camp within Naval Station Guantanamo Bay (NSGB), on the coast of Guantanamo Bay, Cuba.

The GMOC is a distinct facility from the detention blocks used to hold terrorism suspects and "illegal enemy combatants". In the past, the GMOC has usually held a small number of Haitian and Cuban migrants who were detained at sea but sometimes held larger numbers when those countries were in political turmoil, like during the Haitian refugee crisis or the 1994 Cuban rafter crisis. The detention of migrants at the GMOC has been previously criticized by human rights groups and been the subject of lawsuits.

The GMOC was the focus of an initiative announced on January 29, 2025, under President Trump to greatly expand the facility so it could hold 30,000 of the "worst of the worst" migrants, with some being held indefinitely. The expansion of the facility has been questioned on legal, logistical, and humanitarian grounds. While Trump's presidential memorandum specified that migrants would be held at the GMOC, some migrants have been brought to Guantanamo and held by military guards at Camp 6, a military prison previously used to hold Al-Qaeda suspects.

Since the announcement of the expansion of the GMOC, various small groups detainees have been flown on and off the facility. In February 2025, 178 Venezuelan migrants were moved to Guantanamo Bay, with 127 being held at Camp 6 while the remaining 51 were held at GMOC. All but one of these migrants were reportedly deported back to Venezuela via Honduras, with the remaining migrant moved to another detention facility by February 20, 2025. As of March 14, 2025, all detained migrants had been moved off the base. Later more detainees including Nicaraguans had been shuttled to the base. The estimates were by the end of March that less than 400 detainees had been sent to the base at any time. The estimated costs of implementing Trump's executive order to expand the GMOC has been $40 million in the first month of operations.
