Guantanamo immigration – Internal documents reviewed show Guantanamo’s immigration detention effort holds a tiny fraction of its promised capacity and costs far more than expected.
A promise of 30,000 immigration detention beds at Guantanamo Bay is landing in the real world with striking emptiness, according to internal federal documents reviewed for Congress.
The plan was unveiled shortly after President Donald Trump returned to the White House, when he announced the U.S.. military base in Cuba would be repurposed as a large-scale detention center for people facing deportation under his crackdown on illegal immigration.. But more than a year later. the detention facilities are reportedly operating well below public expectations. with figures indicating only a small handful of immigration detainees held at the base on a single reported date.
On May 11. federal documents obtained for review show the government was holding just six immigration detainees at the Guantanamo Naval Base.. All of those detainees were nationals of Haiti.. Over the prior year. the documents indicate 832 immigration detainees were transferred to the facility on more than 100 flights. suggesting an effort that has required repeated transport even as the number of people ultimately held at any given time remained low.
The documents also raise questions about how the program is staffed.. According to the review. the number of government employees assigned to the immigration detention mission is higher than the number of detainees.. On the basis of the figures in the materials. employees were outnumbering detainees by roughly 100 to 1. reflecting the heavy operational footprint required to run a facility at the remote naval base.
Costs have continued to climb as well.. Figures provided to Congress indicate the Department of Defense has 522 personnel supporting immigration detention at Guantanamo.. The internal federal documents also describe around 60 U.S.. Immigration and Customs Enforcement and other non-military staff assigned to the mission.. In April, information provided by the Pentagon to Democratic Sen.. Elizabeth Warren indicated the military-only portion of the project was expected to cost $73 million. an increase from a previously reported estimate of $40 million.
Trump said in January 2025 that officials would set up 30,000 detention beds at Guantanamo. Yet the internal documents reviewed indicate the base’s capacity for immigration detainees is limited to roughly 400 beds. On May 11, fewer than 2% of those beds were reportedly occupied.
The contrast between the headline goal and the reported numbers has intensified scrutiny of an effort that has remained largely closed to public view.. Guantanamo’s history is closely tied to the post-9/11 era, when the U.S.. used the base for indefinite detention of terrorism suspects and faced international condemnation amid allegations of abuse and due process violations.
Warren. who received projected cost information for the Guantanamo operation. accused Trump and Defense Secretary Pete Hegseth of wasting taxpayer funds on what she described as a cruel immigration agenda.. The review also indicates attempts were made to seek comment from the Pentagon and the Department of Homeland Security. including whether the administration plans to continue using Guantanamo for immigration detention.
Publicly, the administration has released scant details about the program. The base itself sits on Cuban territory, and the U.S. has long argued its access is based on a lease arrangement, while the Cuban government has said the arrangement is illegal.
Before the second Trump administration. Guantanamo was used in earlier years to hold some migrants intercepted at sea. including tens of thousands of Haitians during the Clinton administration.. But in February 2025, officials began sending groups of detainees arrested by ICE from within the U.S.. to Guantanamo for detention while deportation proceedings move forward.
When the effort began, Trump and senior aides said the plan would focus on the “worst” detainees and “high-priority criminal aliens.” Subsequent reporting indicated that description did not fully match how detainees were being categorized and transferred.
Documents and earlier coverage show detainees have included people with alleged gang or criminal histories. alongside individuals considered lower-risk because they lacked serious criminal records or had none at all.. In addition to those categories, the internal rules governing who could be transferred appear to have given officials broad discretion.. In April. reporting based on an internal government memo said staff had wide-ranging authority. including the ability to send non-criminal detainees to Guantanamo.
The detainees considered “low-risk” have been housed in a Migration Operations Center. a barrack-like facility that had previously held asylum-seekers intercepted at sea.. Those classified as “high-risk” immigration detainees have instead been held at Camp VI. part of the post-9/11 prison complex where some terrorism suspects remain.
Legal challenges to holding civil immigration detainees at Guantanamo are ongoing.. In December. a federal judge in Washington. D.C.. issued a preliminary ruling finding the immigration detention effort at Guantanamo was “impermissibly punitive” and likely unlawful. while stopping short of blocking the operation at that stage.. Lee Gelernt. the American Civil Liberties Union lawyer who brought the lawsuit. argued that using Guantanamo amounts to political theater and said the approach serves no legitimate policy goal given the financial and logistical burdens.
Theresa Cardinal Brown, a former DHS immigration official who served under presidents George W.. Bush and Barack Obama. said the Trump administration’s use of Guantanamo and other controversial facilities such as Florida’s “Alligator Alcatraz” has aimed to pressure people in the U.S.. illegally to self-deport and deter others from attempting unlawful entry.. She said the claimed deterrence effect is difficult to measure. pointing to the fact that illegal crossings at the U.S.-Mexico border have remained relatively low.. Still, she argued the cost is evident.
Cardinal Brown noted that running detention at Guantanamo requires shipping supplies to the base rather than drawing from nearby infrastructure. describing that as a major driver of expense.. Her remarks underscore one of the central tensions in the program: the administration’s stated intent to deter and manage deportations through a high-profile facility. versus reported evidence that the operation is expensive. resource-heavy. and far from the scale announced publicly.
For now. the documents reviewed depict a detention effort that has absorbed significant military. enforcement. and staffing resources while keeping occupancy far below the promised figure—leaving critics to argue that the plan’s impact is more political than practical. and prompting further questions about what role the base will play as the legal fight continues.
