My son is studying in Austria getting his BS. This is something he arranged, he has his student resident visa and has been there for going on two years now, out of three required for his degree. There was no US University to call him home or end his program, therefore he is doing what all of the other students are doing. Staying put, self-isolating and participating in online classes whenever they are scheduled. From what I can tell, they are much more serious about the social distancing than we have been, or at least, they are a couple of weeks ahead of us. He can walk out to the grocery store which is well stocked (they even have tons of tp now, after an initial rush - he just doesn't need a 20 roll package!)
When his classes were first cancelled, I asked whether he wanted to come home. He wanted to stay where he is. He didn't really want to take a train and a couple of planes where it would be impossible to social distance, and then when the online courses were offered, he would be in the wrong time zone. Plus, there is still uncertainty over when they may actually be back on campus and this way he will be there and ready, rather than have a mad scramble for what will likely be limited flights.
Anyway, it seems there are some US students abroad who are still over there studying and living life as temporary Europeans. It has been interesting to hear about his experience.
