So it actually would not require amending the Constitution so much as having Congress tighten the definition of NBC as is in their purview if I’m reading you correctly?
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.
