On November 26, 2007, we mailed a notice requesting additional evidence and/or information in this case. Please follow the instructions on the notice to submit the evidence and/or information requested. This case will be held in suspense until we either receive the evidence or the opportunity to submit it expires. Once you submit the information and/or evidence requested, you will be notified by mail when a decision is made, or if the office needs something further from you. If you move while this case is pending, call customer service.
