More than likely if you send it without the control number batch cover letter and addressed to the error correction dept they may not do anything with it. If it was mailed out the 13th then any day. I got my letter a day early, it was dated for the 15th and i got it the 14th. It will be tomorrow or wednesday so it will be worth waiting to get it right. And the 6-8 weeks delay on it is a generic response they give, basically once you get it faxed give it a week to see if they recieved it. Once they tell you its been put back into process it takes anywhere from 7-21 days to go back through the regular processing system.
