This one isn't as bad as some other things that have already happened in the space, but I've been wondering...

If I was a non-US person, who previously wanted to visit or move the US -- as a student, industry engineer/scientist, academic researcher, teacher, doctor/nurse, investor/founder, conference attendee, or tourist -- recent news events would've already had me put that wish on hold, indefinitely.

Even though those all are people that the US wants coming, they are being discouraged.

So, who has the US already started missing out on, what are the situations of people who are still coming, and how soon will even they stop?
