First, there is a difference between actual “green card holders” and what Reuters’ interpretation of what that phrase might mean.
Green card holder ‘returning’ to the US (meaning they obtained one in the US and left briefly and want to return to the US) and an approved Visa to ENTER are two different things.
Green cards are for people who have already entered the US and are here legally. Visas to enter are another thing.
Either Reuters or the administration need to be specific.
I read through some of this yesterday, and it does indeed appear that green-card holders who are citizens of those 7 countries are going to experience additional screening if they’re out of the US and trying to return. I don’t know if those already in the US are going to be re-screened.
