It is your understanding that the 14th Amendment grants Birthright Citizenship only to the following:
1) Babies whose Parents or Parent are Citizens
2) Babies whose Parents or one Parent are LEGAL RESIDENTS of the USA.
Babies born in the U.S. whose parents are citizens? Yes.
Babies born in the U.S. who have one alien parent? Not necessarily. If both parents have an established permanent domicile in the U.S., then probably yes via the U.S. v. Wong Kim Ark ruling. If the alien parent is only in the country temporarily, then not necessarily. It would depend on whether the alien parent's country asserts jus sanguinis citizenship that specifically applied to the alien's child, as happened in Obama's case.
RE: If the alien parent is only in the country temporarily, then not necessarily.
Then we have to really check Bobby Jindal’s status. I don’t think his parents were permanent residents at the time of his birth.
