Obviously he'll need his permanent residency card.
Aside from that, since we're traveling to his citizenship country--do we need to take his passport?
We had previously applied for an Advanced Parole document and received it. Does he still need to bring that?
Is there any other documentation he will need to either enter or leave Australia, or to come back to the US?
We leave in a month, so any help would be very much appreciated! I want to prevent a honeymoon nightmare! Thank you so much!
