So your contention is that a legally admitted foreigner - not a citizen, not an ambassador - is not subject to the jurisdiction of the United States?

There you go again. I've provided you with the decision of the Supreme Court in Elk v. Wilkins penned by Justice Gray himself. You have no difficulty with his being authoritative elsewhere as in Wong Kim Ark. But you do here, and that is curious.

"Subject to the jurisdiction thereof" means political allegiance, not some simplistic notion of liability for fine or arrest for jaywalking. That has been made clear by numerous authorities, including the "father" of the 14th Amendment himself.
