“subject to the jurisdiction thereof
I fear you might be right, but could one argue that an illegal isn’t subject to the jurisdiction thereof by definition?
I’m way out of my league with legaleese so I’ll leave it for others to decide.”
Whenever an illegal is prosecuted for a crime in the US, the nearest Mexican consulate must be informed because the person is still subject to the jurisdiction of Mexico. It seems that they may not be wholly under US jurisdiction after all.
