That’s the official number from 5 years ago I believe, so the number is most certainly higher unfortunately.
I’m pretty sure they don’t deport people who come here and have a kid hence the term anchor baby. Could be wrong though.
Most of theses people use their kids as a shield and for citizen ship anyway so I really don’t have much sympathy for them.
It’s not the children’s fault of course, but I don’t see why we grant citizenship on the basis of you being born here. It encourages illegal immigration.
