Obama's mother was 18 at the time of his birth not 19. Statutory requirements state that a parent must be a citizen for at least 5 years past their 14th birthday to pass citizenship to their child. Therefore, Obama's mother could not provide Obama with US citizenship.
That rule (which has since been changed) only applied IF Zero was born outside the United States. IF he was born on US soil, her age was of no consequence, and she could have conveyed US citizenship to him. That is why they had to fabricate the two phony birth certificates.
“Statutory requirements state that a parent must be a citizen for at least 5 years past their 14th birthday to pass citizenship to their child.”
NOT if the child was born in the USA. Neither parentage or age has any role, if the child is born in the USA.
“The Framers’ drew on Emmer De Vattel’s definition of Natural Born Citizen (from his famous work, “Law of Nations”) when they wrote it into our Constitution. It was the highest and securest bar they could place on the office of president, to prevent usurpation by someone with divided loyalties.”
Ah yes...they drew on a poor translation made in 1797 to write the Constitution in 1787.
All natural born subjects of England in the Colonies became natural born citizens of the US at Independence, unless they took some action to reject US citizenship. That shows the two terms are legal equivalents, and NO ONE denies that a natural born subject could have TWO alien parents.
It is also worth remembering that the NBC clause didn’t exist in the original draft of the Constitution - only residency. It appears to have been added without discussion by a 5 man committee between 8 and 12 September, 1787.
