Handbasket Update

I've been working on getting an American Visa for the past 4 years now. They finally sent me a letter telling me that they are now ready to begin processing my request - (Read "we wasted 4 years of your life now only another 4 years to go!") So anyway this last letter that they sent me said that they would like to continue processing my request but can only do so after they make sure they have my correct address. Need I state the obvious? How would I be able to sign the paper if they didn't have my address? Oh well I'm sure they are just headed down the road paved with good intentions much like the rest of us.
