“What is the definition of natural born? There are three ways to become a US citizen, birth thru blood, jus sanguinis; birth on US soil, jus solis; and naturalization. The first two are, IMO, natural born. If Obama was born in the US, he is a natural born US citizen. If he was born in Kenya, then he has a problem.
Birth on US soil=native-born. But this is NOT, as some here seem to think, equivalent to “natural born.” If the framers had wanted to simply tie eligibility to being native-born, they would have used that term. In reality, at the time of the Constitution, native-born children were NOT automatically citizens. http://federalistblog.us/2008/11/natural-born_citizen_defined.html
Whoever suggested natural born is restricted to a person who is a US citizen both jus sanguis and jus solis has a good idea. But if that were the intent of the framers it’s hard to understand why the first Immigration statute labelled those born abroad of 2 US citzens “natural born.” Admittedly, this was repealed 5 years later with identical language that still accorded such individuals automatic citizenship, but removed the term “natural born.” The point is IF the framers believed the jus sanguis + jus solis definition of natural born, this statute would not make sense.
However, this does not preclude viewing “natural born” as being restricted to individuals whose allegiance is undivided.
