Interestingly, an illegal alien who has no contact with the US government and is working under the table would not be a subject, and is not under the jurisdiction of the United States. However, if that alien has been convicted of a crime and is in prison, then technically, until he is released and deported, he would be subject to the jurisdiction.
So in order for an illegal alien to give birth to a citizen, the illegal alien would have to be in prison when the child is born.
So technically, there is a loophole.
That’s hysterical in its own weird way.
