The Trump administration has arrested two foreign students, including Mahmoud Khalil, a green card holder, and revoked the visa of another student, Ranjani Srinivasan, who then left the U.S. Federal agents also searched on-campus residences of students involved in protests.

International students and faculty have become increasingly fearful, with many feeling unsafe to express their opinions or participate in campus activities. This has led to a 'chill' in academic discourse and debate.

Critics argue that these actions infringe on free speech and set a precedent where non-U.S. citizens could face deportation for expressing dissenting views on global issues. This has raised concerns about the potential for further visa revocations and arrests.
