Pending the promulgation of revised directives pertaining to enhanced social media vetting protocols, the State Department has instituted a temporary moratorium on scheduling new visa interview appointments for prospective foreign students, with an explicit exemption for applicants with pre-existing appointments; this directive, articulated in a cable bearing Secretary Rubio's signature, mandates consular sections to suspend scheduling further student visa appointments until the aforementioned guidance on expanded social media vetting is disseminated, a measure symptomatic of the ongoing recalibration of immigration oversight initiated during the previous administration's crackdown on international student enrollment—exemplified by the revocation of Harvard University's authorization to admit international students and the invalidation of legal statuses for extant international students—and subsequently perpetuated under the current administration's aegis, the protracted curtailment of student visa scheduling potentially jeopardising matriculation timelines for upcoming academic terms and precipitating budgetary repercussions for institutions of higher education predicated on international student enrollment.
