He was not issued any paperwork at all, he was just not allowed to board the plane to the US. I just got off the phone with US Customs and Border Protection and they really stressed that he bring as much proof as he can about having ties back in Italy, and that he has a round-trip ticket. If he is asked about Australia, they said to have places that we will be staying, doing, just a full itinerary. I'm sure that he will be questioned a lot more than normal now that he is in their system.
