Are you nuts? Do you not understand what you yourself quoted? PLEASE be kind enough to tell us what YOU suppose the phrase "and subject to the jurisdiction thereof" means in the 14th amendment

[Anitius Severinus Boethius]

Is the ambassador from Ireland subject to the jurisdiction of the United States while in the United States?

No.

His child, therefore, is not automatically a United States citizen when born here.

He is not “subject to the jurisdiction thereof”.

Someone who crosses the border illegally is “subject to the jurisdiction thereof”.

The Constitution is clear. We need to change the Constitution to correct this.

[Varda]

“and subject to the jurisdiction thereof”

It means that the tag “illegal” or “legal” can be placed on something you do. This means that yes, illegal immigrants are subject to the jurisdiction of any country that can tag them such.
