“Via the passage above it seems one is EITHER born a “natural-born citizen(s)” or one is born an “alien(s) or foreigner(s)”. If one is born an alien or foreigner one may be NATURALIZED as a US citizen. Thus the two types of US citizen clearly recognized by US law, natural born or naturalized.”
The passage you quote is taken from Vittals Work “Law of Nations” not from US law as you imply. If you had quoted the whole Paragraph we would see that Vittal defined Natural Born or Indiginious Citizens as being born on the soil to 2 citizen parents. All others are aliens or foreigners.... Why did you leave that part out? Shame on you!
The only area that being an NBC matters in US Law is as an eligibility factor for becoming President. Serving as President is not a right a citizenship...as stated in the Constitution there are eligibility requirements, one of which is being born in country to two citizen parents ie a Natural Born Citizen.....
It should be noted that no matter how one obtains US citizenship, all citizens assume the same rights and responsibilities.....but not all are eligible to become President......Obama is one such person not eligible, but mistakenly sworn in as POTUS nonetheless.....On that fact there is no doubt......the real question confronting us now is what to do about it........
The Constitution does not say that the eligibility requirements include being born in country to two citizen parents, it says natural born citizen.
“As much a citizen” as cited in Kim Wong Ark doesn't mean “a citizen but not natural born”. They found according to English precedent that he would be a “natural born subject” and applying the same principle to an American “as much a citizen” as the natural born child of citizens.
