The U.S. immigration system has detained and deported American citizens, often without recognizing their status, and safeguards designed to prevent this error have repeatedly failed. GAO found ICE deported 70 potential U.S. citizens between 2015 and 2020, with an additional 674 arrested and 121 detained during the same period, revealing a pattern that spans multiple administrations and continues to the present.
The scale is unknown and likely much larger. Northwestern University research suggests approximately 1% of immigration detainees are U.S. citizens—a figure that, applied to current detention levels exceeding 60,000 people, suggests over 2,000 American citizens may be in ICE custody at any given time. None of this is being tracked systematically, and oversight mechanisms designed to protect citizens have been dismantled.

Cases of U.S. Citizens Detained Without Cause
ProPublica's investigation documented 170 or more U.S. citizens held by immigration agents through October 2025, many of whom were subjected to physical force and prolonged custody without phone access or legal counsel. The cases span years and regions, suggesting a systemic pattern rather than isolated incidents.
A representative case: George Retes, a 25-year-old U.S. Army veteran who served in Iraq, was pepper-sprayed by ice agents, detained for three days without explanation or ability to contact anyone, and released without charges. Of ProPublica's tracked cases through October 2025, nearly 50 showed charges dismissed or never filed, and nearly all involved Latino detainees, suggesting the wrongful detentions are not random but follow a demographic pattern.
The System Cannot Track the Problem
The federal government does not know how many U.S. citizens ICE wrongfully detains or deports because neither ICE nor Customs and border Protection maintain adequate records to identify citizenship-related errors. The Government Accountability Office concluded that this record-keeping failure prevents both measurement of the problem and systematic prevention of future cases.
ICE does have a policy requiring supervisory consultation when someone claims U.S. citizenship, but GAO found that training materials communicating this safeguard are inconsistent across field offices, meaning the rule is unevenly enforced. An agent in one field office may follow the protocol; an agent elsewhere may not. No one tracks whether it happened.
Oversight Mechanisms Have Collapsed
The Office for Civil Rights and Liberties (CRCL), which handles detention-abuse complaints including medical neglect and sexual assault allegations, was reduced from roughly 150 employees to a handful in 2025. Over 500 active complaints are currently frozen or uninvestigated—a backlog that means families of wrongfully detained citizens have no functioning way to seek accountability.
The system's ability to locate detained people has also failed. ICE's detainee locator system became unreliable in 2025 as detention expanded, with people "disappearing" for days without families able to find them. For a U.S. citizen wrongfully arrested and detained, not being findable in the system—combined with no access to a phone—makes proving citizenship nearly impossible.
What Congress Is Doing
Congressional investigators launched a formal joint investigation in October 2025 in response to ProPublica's reporting, signaling legislative recognition that citizen detention represents systemic failure, not individual error. The investigation may lead to legislative changes, funding restoration to oversight offices, or ICE policy overhaul—but none of this has materialized yet. The pattern and the response are now documented. What remains is whether Congress will act on its investigation while the surveillance, detention, and transportation systems remain operational and expanding.
Frequently Asked Questions
How do I know if a citizen relative was detained by ICE?
You can attempt to use ICE's detainee locator at ice.gov/detainee-locator, though the system has been unreliable during detention expansion. Contact a local immigration attorney or nonprofit legal aid organization immediately. If someone has been arrested by immigration agents and is not reachable by phone, assume detention and begin legal action at once.
What should I do if I am a U.S. citizen and detained by ICE?
Clearly state "I am a U.S. citizen" to every agent. Request a supervisor and repeat the claim. Do not sign documents you don't understand. Ask for a phone call and a lawyer. If possible, provide your birth certificate, passport, or other citizenship documentation. Document every agent's name, badge number, and what they say.
Is this happening more now than before?
ProPublica's documented cases extend through October 2025, showing an ongoing pattern. Congressional investigation of the problem was launched in October 2025. The exact trajectory is unknown because the government does not systematically track these cases, making it impossible to say whether detentions are increasing or decreasing.
