My friend wants to leave the USA. He entered the country illegally at age 10, he's 21 now, still no papers. He wants to fly from Las Vegas (where he resides now) to Dominican Republic (1 stop in Atlanta). He recently got his mexican passport and a mexican CID card issued by the mexican consulate in Las Vegas. He doesn't have any sort of ID issued by US entities, no american visa. Can he travel without any risk of being deported? He isnt planning to come back so returning to the USA isnt an issue here.
