This isn't a Americas problem, it's a USA problem.
An American went to a trip here in Brazil with his wife pregnant, his wife was Brazilian with a Green card that was married in USA, she entered in the country and her son unexpectedly was born here in the lasts days of their trip.
Do you believe that they can't get to their country anymore with their daughter? Because the kid was born in Brazilian soil, and USA doesn't recognize the kid for not having a bilateral agreement with Brazil.
USA is a mess
