Got to know my interview date (Oct. 20, 2009)!
My status changed to SENT TO
DO FOR INTERVIEW 2 weeks back. As still hadn't received the interview letter called the USCIS 1-800 #. They said still there is plenty of time for the letter to arrive!
Here's the other thread where I was discussing the possibility of getting INFOPASS appointment for duplicate letter:
