I don't think that's accurate. I think his mother became a citizen before his birth. It was his father there are questions about. His father, though, had been an immigrant. Had returned to Cuba apparently due to the instability and revolution, and apparently with the intent of getting his wife (wife-to-be?) to the US. He accomplished that.
He then did appear before the authorities for immigration well after he'd lived here for 2 years. He then accepted various jobs in various locations as an acceptable immigrant and as a Cuban refugee, based on that law as well.
He would have met the requirements for citizenship of the original immigration and citizenship law if he had lived under that first law in the 1790s.
So, if we're going to apply a 1700s definition of "natural born", then we must also apply the first law of the 1790s (1793, I think), to his case.
Had the same situation applied in Rubio's case in the 1790's, there would have been no denying Rubio's natural born citizen status. Both parents had gone before the authorities after two years residence and indicated their desire to be here. Rubio had been born prior to that in the US.
I have no problem with Rubio as a candidate. Jindal, on the other hand, was not born to citizen parents.
The problem is not whether the parents were "citizens" at the time of the candidate's birth, but whether the parents were both "under the Jurisdiction of the United States." Rubio's parents became permanent residents under US Law the second they set foot on US soil and requested asylum. This was in accordance with the law. Rubio's parents had no country to return to. Their intention from the day they set foot on American soil was to make the US their domicile and to become citizens (which they did).
Jindal's parents were both here on Student Visas and therefore were subject to immediate deportation without a hearing and they did not place themselves under the Jurisdiction of the United States by applying for permanent residency or citizenship until after Jindal was born. Both of Jindal's parents were "subjects" of the Sovereign Country of India at the time of his birth and were not "subjects" of the United States.
Rubio's parents, by law, both became "subjects" of the United States immediately upon setting their feet on US Soil.
Therefore Rubio is a Natural Born Citizen of the United States.
Jindal was born a subject of the Country of India and therefore he cannot be a "natural born citizen" of the United States.
At no time in Rubio's life was he ever a citizen or subject of any country other than the United States.
