My aren't we a pleasant one this morning? I quoted from the legislation you asked about. But by all means let us know what you think "subject to the jurisdiction of" means. This should be good for a laugh.
The question is why are you arguing for the children of foreign nationals to become citizens under the 14th amendment?
I'm not arguing anything. You asked and I answered, and assuming you were actually interested was my first mistake. The law is what the law is, regardless of whether we like it or not.
