Only in America, did a nation's founders recognize that rights, though endowed by the Creator as unalienable prerogatives, would not be sustained in society unless they were protected under a code of law which was itself in harmony with a higher law. They called it "natural law," or "Nature's law." Such law is the ultimate source and established limit for all of man's laws and is intended to protect each of these natural rights for all of mankind. The Declaration of Independence of 1776 established the premise that in America a people might assume the station "to which the laws of Nature and Nature's God entitle them.." It is clear that you lack a basic understanding of Natural Law and it's importance in the framing of our Constitution.

So, Blackstone doesn't help you any.
From Blackstone's Commentaries:
When I say, that an alien is one who is born out of the king's dominions, or allegiance, this also must be understood with some restrictions. The common law indeed stood absolutely so; with only a very few exceptions: so that a particular act of parliament became necessary after the restoration, for the naturalization of children of his majesty's English subjects, born in foreign countries during the late troubles. And this maxim of the law proceeded upon a general principle, that every man owes natural allegiance where he is born, and cannot owe two such allegiances, or serve two masters, at once. Yet the children of the king's embassadors born abroad were always held to be natural subjects: for as the father, though in a foreign country, owes not even a local allegiance to the prince to whom he is sent; so, with regard to the son also, he was held (by a kind of postliminium) to be born under the king of England's allegiance, represented by his father, the embassador. To encourage also foreign commerce, it was enacted by statute 25 Edw. III. st. 2. that all children born abroad, provided both their parents were at the time of the birth in allegiance to the king, and the mother had passed the seas by her husband's consent, might inherit as if born in England: and accordingly it hath been so adjudged in behalf of merchants. But by several more modern statutes these restrictions are still farther taken off: so that all children, born out of the king's ligeance, whose fathers were natural-born subjects, are now natural-born subjects themselves, to all intents and purposes, without any exception; unless their said fathers were attainted, or banished beyond sea, for high treason; or were then in the service of a prince at enmity with Great Britain.
