” I would add (opposite of some) that
you can’t lose NBC status , but you can lose citizenship status.”
Thanks for the kind compliment, but unfortunately a person can lost natural born citizen status as demonstrated by Michelle Bachmann and Malvina Stone.
Malvina Stone was a natural born citizen of the U.S. living in Vermont when she married William Arthur in Dunham, Quebec, Canada. They lived and had a daughter in Dunham, Quebec, Canada before moving across the border into Vermont. While they were living in Vermont, she gave birth to Chester Arthur on 5 October 1829. At the time of his birth in 1829, Chester Arthur’s father, William Arthur, was a British citizen, who did not naturalize as a U.S. citizen until many years later. Chester Arthur’s mother, Malvina, expatriated and lost her natural born U.S. citizenship when she married a British citizen husband. Because his father was a British citizen and his mother became a British citizen and lost her natural born U.S. citizenship upon marriage, Chester Arthur was born with his parents’ British citizenship and acquired no U.S. citizenship at all. There is no known record of Chester Arthur naturalizing as a U.S. citizen.
In the case of Michelle Bachmann, she was a natural born citizen of the U.S. who married a Swiss citizen, acquired a Swiss passport, acquired dual citizenship with dual allegiance, and acquired thereby a divided loyalty that invalidated her sole allegiance to the United States from birth that defines status as a natural born citizen of the U.S. Michelle Bachmann is now a citizen of the U.S., but she is no longer a natural born citizen of the U.S. due to her obligations of allegiance to a foreign citizen husband and period of foreign citizenship alienating a part of her sole allegiance to the United States.
Hope that explanation is understandable and helpful.
I think the intention is as you state it - never any division of loyalty, on any basis, from the day you are born until the day you take the office.
