Definitely. Our vetting system is already a 6 or more year process which covers any & every possibility for people trying to become Americans. No need for a ban. It's UnAmerican to ban any peoples from our country if they are vetted. Another Trump order that should go back to the way it was during Obama's terms where he deported many people BUT WITH the backgrounds that showed they were the type of people who should not stay. Trump's throwing people out who have followed the rules. That is horrific. It must stop.
