The Trump administration expanded travel restrictions that block or limit entry from dozens of countries—moves university officials warn will shrink the pool of international students and scholars. The new proclamation, effective Jan. 1, increases the list of full or partial bans to 39 countries and blocks F and J visa access in many cases, the categories most used by international students and visiting researchers. Higher-education groups including NAFSA and the Presidents’ Alliance said the policy risks U.S. competitiveness in global talent recruitment and could reduce enrollment at programs that rely heavily on international tuition. Universities with large cohorts from affected countries are assessing enrollment and contingency plans while urging lawmakers to seek exceptions for academic institutions. Admissions and international-student offices expect enrollment declines in affected programs and are planning targeted recruitment in non-restricted markets while intensifying calls for institutional support and policy intervention.
