In English Common Law in 1776, which passed to all 13 states at independence, the term Natural Born Subject (which became Natural Born Citizen at independence) had a very specific definition per Blackstone. Every lawyer in the newly independent states, including those at the Constitutional convention would have owned a copy of Blackstone’s Law Dictionary and knew what the phrase meant:

“ The first and most obvious division of the people is into aliens and natural-born subjects. Natural-born subjects are such as are born within the dominions of the crown of England, that is, within the ligeance, or as it is generally called, the allegiance of the king; and aliens, such as are born out of it. Allegiance is the tie, or ligamen, which binds the subject to the king, in return for that protection which the king affords the subject. The thing itself, or substantial part of it, is founded in reason and the nature of government; the name and the form are derived to us from our Gothic ancestors.”
Any person born within the boundaries of the United States is a natural born citizen of the United States, period. This is regardless of their parentage, as defined by both the Common Law and the Constitution. Any person born elsewhere in the world who has at least one US citizen parent is also a natural born citizen, because the laws of the United States state they have citizenship from birth.
The only Americans who are not natural born citizens are those who were naturalized after birth either by adults applying for citizenship, or minor foreign born children who became citizens when their parents were naturalized, or who were adopted by American parents.
Any other definition, such as the Swiss legal scholar Vattel is foreign to the Common Law and does not apply to the Constitution and Laws of the United States of America.
How can a person be a NBC if their parents citizenship gives them an option to be a citizen of another country?
BULLSHIRT!
ENGLISH LAW? BLACKSTONE?
We fought a war to escape from English tyrannical laws.
Citizenship requirements for our new presidency will not be set by BRITISH LAW.
Sir, you are full of %$#@!
