Is a person from another country who walks into US borders automatically a US citizen?
You should have asked me that before leaping to ridiculous assumptions.
Of course not. Why would they be?
All land within US borders is owned by someone or by a civil entity.
Are they trespassers?
Already asked and answered. If you didn't understand the answer, you're welcome to re-read as many times as necessary to figure out what I said.
Your answer assumed there is non-owned US land.
Such does no exist.
It would seem you want to define trespassers as trespassers but are too identified with the left to just come out and say it.
Again, it varies from state to state. Some states yes, others no. I can't even begin to guess why you're having difficulty grasping that?
Now then, I asked you a question.....
I answered your question, "is a person from another country who walks into US borders automatically a US citizen?"
I answered, "of course not," and asked ....
why would they be?
