NBC under the 14th amendment depends on the father being a citizen too
a person born a dual citizen isn’t nbc.
In Inglis v. Trustees (1830) and Elk v. Wilkins (1884), the Supreme Court ruled that a child born on U.S. soil, to a father owing allegiance to a sovereignty other than the United States, inherits its father’s (foreign) citizenship. Such child is not a U.S. citizen at birth [20]
I agree with your conclusions. I think the Wong Kim Ark case used the wrong meaning of “subject to the jurisdiction” too. I’d be stingy with citizenship, I think that is the paradigm of the constitution. But, the people at the controls today want to be generous with citizenship, so everything is read in a way to obtain that outcome.
