If Obama was born in the US and his mother was American and his father wasn’t a foreign diplomat, Obama would indeed be a US citizen by birth. If his parents’ marriage was invalid, then Obama would have inherited his mother’s American citizenship. See the interesting case of Australia’s current PM who got around a real ban on foreigners’ children serving in Parliament by claiming that his parents weren’t married and that no father’s name appeared on his birth certificate.
theres also questions surrounding obamas mother regarding her hawaiian residency. it has appeared she gave birth after statehood but had been a resident only a few months
By the 14th amendment. Not the same thing as a natural citizen.
If his parents’ marriage was invalid, then Obama would have inherited his mother’s American citizenship.
This is correct. I used to know the legal term for this, but American law has always said that if the father is unknown, the child inherits the Mother's citizenship.
But that's still not "natural" citizenship under the Vattel definition, which is the correct definition.
