Yes really you Dipshit.
As I said there's nothing precluding that. You can be a citizen of multiple countries, Dumbass. Being a citizen of one country doesn't prevent you from being a citizen of another unless one of those countries makes that conditional of being a citizen of theirs. Ours does not. I myself am a dual citizen.
I'm calling you stupid because you said illegals weren't subject to jurisdiction of the United States. You likely don't understand what many of those words mean, let alone in conjuction with one another.
