Less Than a Month

My private loan went through without a hitch and will be dispersed on the 27th. My visa, however, is nowhere to be seen. I've checked the USPS tracking code for its envelope every business day since I sent my packet to the consulate but it hasn't been mailed out yet. I can tell it's been received: there's a record of the visa officer having signed for it. I really don't want to call about it and give that guy an opportunity to yell at me but there are only 5 business days left until their "maximum" amount of processing time will have been exceeded. I've been contemplating a friendly email but still think my best bet is simply praying about it. Needless to say, with a mere 24 days left, this is making me very nervous!
