The US Department of State's new visa revocation policies are targeting international students involved in global activism, particularly through social media. The "Catch and Revoke" initiative scrutinizes students' online activity, with some having their visas canceled for liking or sharing posts supporting controversial causes. The crackdown, which affects both current and prospective F-1, M, and J visa holders, has sparked concerns about the erosion of free speech and the future of global student activism.
