Sept. 18 (UPI) -- The fall semester has arrived with fewer international students on campuses in the United States.

NAFSA: National Association of International Educators estimates that the United States will lose $7 billion in revenue and produce about 60,000 fewer jobs due to a 15% drop in overall enrollment this academic year. Contributing to the enrollment decrease is a projected 30-40% decline in new international students.

The estimates are based on State Department and Student and Exchange Visitor Information System information, which is published monthly. There are a few factors contributing to the decline in international students and the primary drivers are related to U.S. visa and immigration policies.

Since its initial revocation of student visas, the Trump administration has begun restricting visas from 19 countries. In late May, the State Department paused student visa processing for three weeks, causing delays for students trying to come to the United States.
