It’s not a travel ban, it’s a ban on all immigration like his previous “travel” ban towards select countries. It means people like me who married a non-citizen cannot have their partner live in the US.
So I could apply, spend thousands of dollars, wait years, and only have a 1/20 chance of being awarded a waiver.
