My wife received RFE after her citizenship interview on 02/12/13 at Chicago. The interviewing officer wanted originals of my divorce document mailed to his attention after her interview. We sent my original divorce document along with G884 filing and the officer returned my original document within 3 weeks, but we neither got any update on the RFE response review nor the case is moving forward despite an Infopass appointment before a month and a service request through Tier 2 a week ago. During the Infopass, the officer at the enquiry desk informed us that our IO hasn't worked on our case yet and it's idle with him for more than 90 days. Pls advice how to make the IO work on our case or what should be our next step, since it has already passed 120 days after the interview.
