You're right, and I did correct myself in my previous post. But my point still stands in relation to Obama.
In “U.S. vs Wong Kim Ark” the court found that Wong Kim Ark was “natural born” despite having BOTH parents as non-citizens.
I do not agree with the finding, but it is (so far) the law.
Are you unfamiliar with the findings of “US vs Wong Kim Ark”? It is in the title of the thread.
There is no requirement that both parents be citizens for a child to be a natural born citizen of the USA; and certainly not a requirement that both parents be natural born citizens as that would make attaining the status impossible as EVERY American has a great to the n’th degree grandparent who wasn't natural born.
