Nonsense. Treaty provisions are subject to the treaty clause of the Constitution.<quoted text>no, the children born to aliens in this country assume the citizenship of their father's country, that is the right of that country and the US can not strip that citizenship away, unless requested by naturalization.
We practice the same, when our children are born off-shore.
All aliens while here are under, local, state and Fed. statutes by treaty, but never subject to the US Constitution.
BTW, a person born of US citizens in Canada is a US citizen per 8 USC 1401, but also is a Canadian citizen per Canadian law.
It is an infantile notion that citizenship by birth in a foreign country "strips that [US] citizenship away," or that citizenship by birth in the US "strips away" foreign citizenship.
Put your play robe and gavel back in your toy box and grow up.
Indeed. EVERYONE who is in the USA except for the children of foreign diplomats is subject to the jurisdiction of the USA. Foreigners who are visiting the USA are not bound to the US Constitution, but if they have children in the USA, the children have allegiance to the US Constitution; they are Natural Born US Citizens.
