Students are generally being told to contact their university's foreign student office (or whatever it's called) before planning any foreign travel, although for many students not from one of their seven countries, this can generally be good advice, particularly if someone has a single entry student visa. Obviously the advice provided by universities can be of varying qualify. I would hope that students with ties to the seven countries would seek information from other sources too.

By late January, most foreign students would already be in the USA for winter quarter or spring semester courses. The exception could be colleges on a 4-1-4 calendar, which often feature off campus or international projects during the January term.

Others caught by the timing would include graduate students participating in conferences abroad or those interviewing for jobs outside of the USA.
