No law written by Congress changes the Constitution.
Natural born citizen means born here of citizen parents, same as when it was written into the Constitution.
One is NATURALLY a US citizen ONLY when one CANNOT be anything else.
No foreign birth
No foreign parent(s)
No foreign citizenship(s)
Sorry you are wrong.
There is no definition of NBC in the Constitution.
One is Naturally a US Citizen when they are born a US Citizen and do not need to be naturalized.
The Constitution specifically gave Congress the unrestricted authority over all rules of Naturalization. That includes who needs to be naturalized and who does not.
The first definition of NBC status we see came from the first acts of Congress and includes those born to US citizen parents beyond the borders of the US.
