COVID-19 border closures (2020)
Pandemic travel bans and consulate closures cut student-visa arrivals to the lowest levels in years. Campuses moved classes online and new international enrollment collapsed.
Universities lost tuition revenue and deferred admissions for a year or more.
Enrollment rebounded through 2022 and 2023 as restrictions lifted and visa processing restarted.
Nature uses 2020 as the benchmark: August 2026 arrivals are the lowest since that pandemic trough, but this time the cause is policy rather than a global shutdown.
