I'm kinda disappoint that the ban is based on country and not whether the individual has negative views towards the Kafir or the USA.
1) isn't trivially avoidable ("are you now, or have you ever been, a Militant Islamist?"), and
2) doesn't rely on extending the surveillance state further.
maybe creating secular activities for them other than mosque would help them.
"Do you hate America?"
"No"
"K, let him in"
