I can't make heads or tails from this. I see restrictions similar to a year ago with lots of exceptions. I see no mention of students. One nation singled out here is Brazil and my school gets many students from there.
Ours come almost entirely from India. Chances are very good they won't be able to come, so we've designated online asynch courses for them. Those enrollments are expected to fall, though.
