Illegals are subjects of the country they came from. In other words, Mexicans who enter illegally are STILL Mexican citizens. They are NOT USA citizens just because they crossed the border. They still have allegiance to Mexico.
As to whether they have diplomatic immunity, no because they are not registered agents of Mexico otherwise they would be able to commit crimes and not be arrested (just like diplomats). Being a non-registered agent does mean they are “under the juristiction”.
You go and try giving birth in Mexico to see if they give your kid automatic Mexican citizenship. It ain’t happening.
“In other words, Mexicans who enter illegally are STILL Mexican citizens.”
I don’t think anyone argues that.
“Being a non-registered agent does mean they are “under the juristiction”.”
No, but being within our borders, without some special diplomatic status does mean they are “under the jurisdiction” of the United States. As I said, if they aren’t under the jurisdiction of the US, then they cannot be charged with a crime if they violate our laws, as that is the simplest demonstration of jurisdiction. You yourself admit they can be charged with crimes, so you have also admitted they are under the jurisdiction of the United States while they are here, whether you wanted to or not.
“You go and try giving birth in Mexico to see if they give your kid automatic Mexican citizenship. It ain’t happening.”
Mexico’s laws are irrelevant as to what the laws of the United States are. So this is just a distraction.
