The right of citizenship never descends in the legal sense, either by the common law or under the common naturalization acts. It is incident to birth in the country, or it is given personally by statute. The child of an alien, if born in the country, is as much a citizen as the natural born child of a citizen, and by operation of the same principle. [p666]
as does the Constitution, uses "citizen" distinctly from "natural born". Why do you suppose the Constitution draws that distinction?
I think you need to read the whole thing.
““Natural-born British subject” means a British subject who has become a British subject at the moment of his birth.” “Subject to the exceptions hereinafter mentioned, any person who (whatever the nationality of his parents) is born within the British dominions is a natural-born British subject. This rule contains the leading principle of English law on the subject of British nationality.”
Those born in the country ARE natural born subjects/citizens. There are also naturalized citizens. Two categories of citizens.
“It thus clearly appears that, by the law of England for the last three centuries, beginning before the settlement of this country and continuing to the present day, aliens, while residing in the dominions possessed by the Crown of England, were within the allegiance, the obedience, the faith or loyalty, the protection, the power, the jurisdiction of the English Sovereign, and therefore every child born in England of alien parents was a natural-born subject unless the child of an ambassador or other diplomatic agent of a foreign State or of an alien enemy in hostile occupation of the place where the child was born.
III. The same rule was in force in all the English Colonies upon this continent down to the time of the Declaration of Independence, and in the United States afterwards, and continued to prevail under the Constitution as originally established.”
