It seems that you got 221g for the same reason that I got: PIMS verification. The consular officer had also told me that it will take them 2-3 days to get it verified. I had mentioned to him though that I had my flight five days later, and he had said that that shouldn't be a problem. I hope though that you have more than a week before you come back

Just keep mailing the consular office (email add should be up there in this thread) to check the status. They notified me when they received the PIMS number but they wouldn't tell me anything about my PP and Visa. After getting too generic answers I went to the embassy myself (since I was to fly a day later) to check the status. They have a free counseling session to everyone from 1:00-3:00pm everyday. They canceled the session the day I went there but I made my case to the guards there, who fortunately understood my situation and let me enter the facility. I had my passport back a few minutes later!

If you are not short on time, just relax and enjoy and keep mailing the embassy from time to time. Otherwise, you gotta do what you gotta do!
