Great Britain did not have a naturalization process. The United States does.
The difference between "natural born subject" and "natural born citizen" are manifest. It is common sense.
Here is David Ramsay:
People changed from subjects to citizens [and] the difference is immense. Subject... means one who is under the power of another; but a citizen is an unit of a mass of free people, who, collectively, possess sovereignty. Subjects look up to a master, but citizens are so far equal, that none have hereditary rights superior to others. Each citizen of a free state contains, within himself, by nature and the constitution, as much of the common sovereignty as another.
"And the thirteenth adopted the common law rule for citizenship."Waiting...Cite the statute or state Constitution reception.
