In my view, Born ...........and subject to the jurisdiction thereof.
There are two groups in the 14th amendment. This is settled law, by the way.
A person who isn't in ANY of those groups (and this is what the majority in Bellei said), can be made a full fledged citizen by naturalization. The dissent says Bellei in in the 14th amendment, but not born in the US.
Bellei actually argued that he was born in the US! No kidding! He produced an Italian BC, and said, see, I was born in the US. Funny stuff.
