I don’t think she is a natural-born citizen.
As far as I know both her parents lacked US citizenship at her birth.
I believe the British 1730 natural-born citizen law essentially required a father only to have had British citizenship.
She was born in the US, doesn’t matter her parents’ citizenship.
YOU are CORRECT-—
NIKKI IS NOT NATURAL BORN CITIZEN
SHE IS AN ANCHOR BABY——NOTHING ELSE
