Thanks guys. Yes, I thought about having someone I know personally deliver the documents, but nobody I know is going to China any time soon. I'm a medical student with no vacation time this year, so I can't be the one to do it, as much as I wish I could be there for him on interview day. We're still waiting for packet 3 now, but I think I will look into that possibility of getting special permission to submit prior to interview that you mentioned, Randy W. If they say that's not allowed, I will just go ahead as sole sponsor and see what happens... even before my parents transferred the money, I was pretty close to having adequate income/assets.
