As a NON-CITIZEN he has NO RIGHT to SUE anyone!
About ten years ago I got selected for jury duty, put in the 1st chair. No excuse got me off. It was about an illegal suing because he got injured while trespassing and robbing a business. After we're all selected and seated, judge asks me one more time if I can be fair to the plaintiff. I said "Yes, just as long as this illegal alien was not doing anything illegal!". Courtroom busted up in laughter, and the judge dismissed me as a juror. So yes, apparently non-citizens do sue. It's crazy.
