The Constitution does not in words say who shall be natural-born citizens. Resort must be had elsewhere to ascertain that. At common law, with the nomenclature of which the framers of the Constitution were familiar, it was never doubted that all children born in a country of parents who were its citizens became themselves, upon their birth, citizens also. These were natives or natural-born citizens, as distinguished from aliens or foreigners.Some authorities go further and include as citizens children born within the jurisdiction without reference to the citizenship of their parents.
See the bolded sections. Citizenship is bestowed by jus soli; NBC may or may not be. Go ahead and try to force it, but you cannot. Please see post 653 for more details.
Now consider the underlined section; it talks about natural born citizens as opposed to aliens or foreigners. If you are a citizen then you are NOT an alien or foreigner! The sentence you think is the key - about NBC - actually draws a line between aliens and foreigners (non citizens) and NBCs. It says NOTHING about citizenship AND NBC status.
Bottom line: there aren't any legal findings that define what a natural born citizen is; claiming otherwise is at best ignorant, at worst malicious.
As "distinguished from" -- Right.
And "natives or natural born citizens" were "children born in a country of parents who were its citizens." Period -- End of definition per the chief justice.
"Natives and natural born citizens" were at one end of the spectrum and "aliens and foreigners" at the other. But there was gray area in between. There were immigrants undergoing naturalization and and the children that they were having during that time of naturalization who were considered by the government as aliens and foreigners. That is a fact of history.
These children born here to naturalizing immigrants were at the time treated as "aliens and foreigners" just like their fathers until he took his oath to his new country. These children born to naturalizing fathers were the "aliens and foreigners" that "some authorities" wanted to be considered to be "citizens" -- not "natural born citizens". Read it. It says "citizens" not "natural born citizens".
But at the time those born in this country of fathers who were still not citizens were considered to be aliens and foreigners like their fathers,
Now reread that paragraph from the chief justice and see if it makes more sense to you now.
