Well, yes and no. Congress has already said through enacted immigration law who does not need to be naturalized and is therefore already a citizen at birth. The question that remains is whether or not “citizen at birth” is the equivalent of “natural born citizen” under the Constitution. That would be a question for SCOTUS, but Congress can and should clarify their opinion on the answer.
Lawyer, huh? ;)
Did I not read in your posts that Congress has been known to change those rules from time to time, and that it is within their sphere to define?
