Per the NVC and the GUZ, my K-1 petition has been in China since 1/26/2008. I have a few questions that I will solicit the experts for answers. First question, where is the petition? Is it with the Chinese Custom Officials or is in the mailroom at the GUZ? Once the GUZ gets it and starts the P3 processing, what exactly do they do? My SO then gets the P3 package, fills it out and sends it back and patiently waits for P4 which I assume is the interview invitation. What does the GUZ do with the case between their receipt of the P3 package and issuance of the P4 package? It seems that the timeframes are all over map. What are the main causes for the variation in processing times? Is there anything one can do to minimize the processing time between P3 and P4? Thank you, -Squonk
