8 U.S. Code § 1401
Says nothing about ‘natural born citizenship’. One can be a us citizen and still not be a ‘natural born US citizen. I will note like the devil courted Eve in the garden the players that wrote this left out the difference in ‘natural born’ citizenship, and citizenship attained from having been born on US soil….
That would make her a statutory Citizen. A statutory Citizen is not a natural born Citizen. Citizen and natural born Citizen are not the thing.
