Identify every single person in this country that is here illegally. There is a legitimate and legal immigration procedure to enter the US with the intent to stay. Follow it or go back where you came from. You have no absolute right to be in this country. This applies to all persons, not just people from South America. You have no right to complain when the immigration law is enforced. I can’t imagine going to any other country and entering that country illegally and expect no consequences.
