The U.S. State Department is poised to suspend scheduling new visa interviews for foreign students and intensify scrutiny of their social media activity; this measure, however, will not affect applicants with pre-existing appointments, as a cable signed by Secretary of State Marco Rubio directs consular sections to refrain from scheduling additional student visa appointments pending the issuance of guidelines concerning the expanded social media vetting process, a move that follows the Trump administration's clampdown on international students, which included measures such as stripping Harvard University of its eligibility to admit international students and potentially revoking the legal status of thousands of international students already residing within the U.S., while the policy of scrutinizing visa applicants' social media accounts has been maintained by the Biden administration, and a protracted cessation of student visa scheduling could significantly disrupt students' matriculation plans for the summer and autumn semesters, with the potential reduction in international student enrollment also impacting university budgets.
