Roughly 100.000-150.000 people living in Austria are currently unable to travel to the US because they are either citizens of Syria, Iraq, Iran, Yemen, Libya, Sudan or Somalia - or Austrian citizens who also hold citizenship/passports of these countries.
And what business or connection do they possibly have here? I have yet to hear a reason as to why the right to immigrate here is apparent universal.
Because, no matter how hard the tiny-brained fascist cult prays to their orange false deity, the United States is still a modern nation and part of the free world, not Trump-istan.
