Jindal's parents are both naturalized citizens. His mother, pregnant with Bobby, was accepted as a graduate assistant at LSU, which offered her a month of maternity leave. His father gained them admission to the US on a P3-1 visa ("professional or highly skilled"). His mother could have gained entry on a student visa, however, then his father would not have been able to work, so they didn't take that route.
His father is now a civil engineer at URS, a large engineering firm, and his mother is Director of Information Technology at the Louisiana Department of Labor.
Therefore, Jindal, having been born in Louisiana, is natural born. As are Rubio and Nikki Haley, for the same reason, namely, having been born citizens. And of course, Cruz as well, being entitled to citizenship by birth because of his mother.
Going by memory from when this was a freeper discussion about 2 years ago, Jindal’s parents were in the US on student visas, and in that same status at his birth.
THAT, however, doesn’t overcome our anchor baby law.
Of course, I’m willing to read evidence that disputes my memory. I’m pretty sure that was the discussion, though.
