The new U.S. Immigration and Customs Enforcement rules were met with forceful criticism from a range of groups, from universities and international students, to tech companies and states.

The administration has said there is no reason for foreign students to be in the U.S. if their instruction is completely online…

Under the rules, international students enrolled at schools planning to teach online-only courses this coming semester would need to leave the U.S. or wouldn’t be permitted to come at all.

Schools planning to teach a mix of in-person and remote courses would be required to host their international students on campus, blocking many students stuck abroad because of coronavirus-related travel restrictions and visa delays from enrolling at all. The rules ensure that, should a school opt to switch to online-only instruction if the pandemic worsens, that decision would amount to forcing their international students to leave the country.
