International students may need to leave U.S.

International students in the U.S. forced to take their classes online -- will soon be forced to leave the country.

The news comes as more and more universities begin to announce plans for the upcoming fall semester.

Harvard University on Monday (July 6) announced it would conduct courses online for the 2020-2021 academic year.

The U.S. Immigration and Customs Enforcement agency announced Monday foreign students must leave the U.S. if their school's classes this fall will be fully virtual -- or transfer to another school with in-person instruction.

In its announcement ICE said students who do not comply -- could potentially face deportation proceedings.

It was not immediately clear how many student visa holders will be affected by the move.

The guidance does not affect students taking classes in person.

But foreign students are a key source of revenue for many U.S. universities as they often pay full tuition.

The move on student visas is just the latest of the Trump administration's new restrictions on legal and illegal immigration during the global health crisis.

Last month, the administration suspended work visas for a wide berth of nonimmigrant workers, arguing that they competed with U.S. citizens for jobs.

The administration has also effectively suspended the admission of asylum seekers at the southern border with Mexico, citing health risks.
