Three major U.S. labour unions have launched a federal court challenge against the Trump administration over what they describe as a sweeping AI-assisted social media surveillance program targeting visa holders and permanent residents.
The unions, United Automobile Workers (UAW), Communications Workers of America (CWA) and American Federation of Teachers (AFT), filed their suit on 16 October 2025 in the U.S. District Court for the Southern District of New York. The complaint names the U.S. Department of State (DOS), the U.S. Department of Homeland Security (DHS), and affiliated agencies and alleges the surveillance system uses artificial intelligence and automated tools to monitor the social media accounts of non-citizens lawfully present in the U.S. for viewpoints the administration disfavors.
At the core of the complaint is what the plaintiffs call viewpoint-based online surveillance. According to the suit, the programme, often referred to as “Catch and Revoke”, scans posts by visa holders and even permanent residents, highlighting content critical of U.S. policy, supportive of rights or deemed “hostile” to American values, and uses that as grounds for visa revocation or other immigration action. The unions argue that such surveillance has created a chilling effect: many members reported deleting posts or refraining from union-organising activity out of fear that expression of dissent might trigger immigration consequences.
The legal challenge insists the program violates the First Amendment to the U.S. Constitution by suppressing free speech and association rights and the Administrative Procedure Act by failing to provide lawful rule-making. The government, in its defence, asserts that this is lawful use of immigration and national security powers, mentioning that visas are privileges and not rights and that assessing foreign nationals for speech that could be harmful was intended by the law.
Internationally, the case highlights increasing tensions between AI-facilitated surveillance and free speech. Should the case succeed, it could influence how democracies such as the UK handle national security, digital rights, and online behaviour monitoring.
As the dispute of law plays out, the outcome may create a precedent regarding the limits placed on social media when monitored by government, the connection of AI in the enforcement of free speech, and how labour rights intersect with digital civil-liberties in the surveillance age.
