If 99% of the people who said 1 + 1 = 3 you'd believe it.
According to Vattel:
“The country of the fathers is therefore that of the children; and these become true citizens merely by their tacit consent. We shall soon see whether, on their coming to the years of discretion, they may renounce their right, and what they owe to the society in which they were born. I say, that, in order to be of the country, it is necessary that a person be born of a father who is a citizen; for, if he is born there of a foreigner, it will be only the place of his birth, and not his country.”
Citizenship follows who the father is, not place of birth - according to Vattel. So...is there any US law that says birth in American does NOT make one a citizen unless your father is a citizen of the US?
Has anyone, applying for a passport, been required to prove their father was a citizen to get a US passport?
Does US law follow Vattel on citizenship?
Of course, the answer isn’t just no, but HELL NO!
“All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States and of the State wherein they reside.”
