Yes, I am on the same boat. I-485 RFE for self on 03/18/04 (emplyment verification), response recd on 04/06/04. I-485 RFE (spouse -marriage certificate etc) on 04/26/04, response recd 05/24/04. Second FP notice dated 06/30/04, notice recd on 07/10/04, for 2nd FP on 07/15/04 (done), LUD 07/20/04 (both self & spouse showing fingerprints received). Fist FP done in Jan 2003
In between I contacted USCIS on 06 July 2004, when it was more than 3 months they got my response to RFE. Not sure whether that triggerred the 2nd FP notice. I am saying this because, though the notice was dated 30 June 2004, I noticed that it was posted on 07 July 2004, just after I called to enquire the status.
Waiting since then..... What is your receipt/notice date? Mine is Nov. 2001, Yes 2001!!
