How many ways can the Trump administration clamp down on international researchers?

The Trump administration recently issued two significant announcements aimed at restricting international students and scholars in the U.S.

The first policy change, announced on July 6, suspends the entry of international students taking online courses in the fall semester, affecting hundreds of thousands of students.

The second policy, announced on July 8, revokes the H-1B visa, which is commonly used by international researchers and academics, and limits the duration of stay for H-1B holders to one year, with no option for renewal.

These changes have sparked widespread concern and criticism from educators, students, and researchers, who argue that they will harm U.S. universities and the broader scientific community.
