I also received an email about RFE and that was date OCt3rd and LUD Oct4th but never received anything as yet. I called USCIS last week and the person I spoke to told me that she is going to put request to resend the document. Don't know what is going on-----my pd is Feb 2002.
I have not received anything yet. As I wrote before, when I called TSC, the IO who answered said that I received the email by mistake! Then I went to an Infopass and the Infopass IO told me that it does not seem to be a mistake and inquired about it. She is supposed to call me once she knows something. I have not heard from her yet and I will most probably go to another Infopass two weeks after the first one (The monday after this coming one) to see what is going on. Let's keep in touch.
