The U.S. State Department has announced that all U.S. visa holders are now subject to an expanded “continuous vetting” process, affecting more than 55 million foreigners with valid visas. This includes tourists, students, and exchange visitors, even those who are already inside the country.

According to a department official, visas can be revoked anytime there are signs of potential ineligibility. This could involve overstaying a visa, engaging in criminal activity, posing a threat to public safety, participating in terrorist activities, or providing support to terrorist organizations. The official emphasized that continuous vetting of U.S. visa holders ensures that any new information that raises concerns can trigger visa cancellation or even deportation.

The monitoring applies to every visa category. If authorities flag concerns, individuals could face immediate removal proceedings if they are already in the U.S. The process, officials say, is more comprehensive than ever before, making it possible for visas previously approved to be revoked without warning.

Since taking office, President Donald Trump has focused heavily on deportations, targeting not just undocumented immigrants but also holders of student and visitor exchange visas. Officials admit the process is time-consuming but insist that it strengthens national security by keeping a close watch on those permitted to stay in the country.

For millions of foreigners, this means that holding a U.S. visa no longer guarantees uninterrupted entry or stay. Experts suggest staying updated on visa rules and ensuring compliance with all legal requirements to avoid complications under the new, rigorous continuous vetting of U.S. visa holders.
