It's been 182 days since my Naturalization interview, the officer handed over a RFE notice to which I responded within 10 days. It was also received by the Officer, but he neither updated it online case status nor taken next step on my case. I made 2 Infopass appointments in which I got very rude response from a USCIS supervisor, who just said they've received the documents & it's upto the Officer to process my case. Did couple of Tier 2 requests - no updates, finally I've now written to Congresswoman 2 weeks back, but no updates yet. How long should I wait to take next step? If things doesn't work with Cong, inq., does this mean I've exhausted all other administrative inquiries? Will things work, if I work with an attorney to get my case processed & how long does it take to process?By reading the above, have I exhausted all admin process? How long will it take to resolve this case by an attorney?
