Seems like the could eventually be twisted against citizens. I don't like it.
Build the wall, but don't start messing with citizenship.
Exactly- would everyonr have to take special steps to prove that your child is an American citizen at birth? How you determine whether someone's parents were here legally or illegally? Do we really want situation where an adult who believes he or she is a citizen finds out they are not a citizen because of some glitch in their mother's visa during birth?
