Carlos, The way it worked for Ling and I, we got a green packge at the China Post Office several blocks from the Consulate. Inside this was Lings passport, with her K-1 VISA stamp inside, and a brown sealed envelope containing all the entry papers needed to enter the USA. This will be opened by the imigration officials at your point of entry in to the United States. I think it is mostly the papers you will submit for your SO's interview. Hopt that helps, Obie
