Whether one meets such a requirement or not, the requirement itself is set by statute and subject to change by statute.
Whatever "natural born citizen" means in the Constitution it is only subject to change by amendment to the Constitution. The words were ratified prior to any legislation and are not subject to any such legislation.
A similar line of reasoning would apply to the necessity of being 35 years of age. Congress has no power to legislate a change to that requirement.
Since the words “natural born citizen” are not defined in the constitution itself, then they are subject to definition by Congress, since Congress gets to make all necessary laws to enforce the constitution.
Therefore, children born overseas to a citizen parent are themselves US Citizens.
What the Courts have ruled consistently since 1898 (U.S. v Wong Kim Ark) is that the citizenship clause of the 14th Amendment is the final word on who is and who isn’t a citizen and what category of the two (and only two) categories “ALL PERSONS” fit into (born or naturalized); and that statutes that have been unchallenged or that have been ruled as constitutional under the 14th Amendment are the supreme Law of the Land.
Its really very simple. A citizen of the United States at birth is a natural born citizen and is eligible to be president or vice president. A naturalized U.S. citizen had citizenship conferred after birth and is ineligible to be president or vice president.
