Thanks for that link, Sethumadhavan. I've been looking around for recent (2010) reports of Atlanta N-400 experiences, without much success. I haven't seen any indication of the kind of speedy receipt of Interview Letter that people at other DOs seem to report. So I'm trying to be resigned to the likelihood that I won't see anything about my case from USCIS until maybe late July. As a white Canadian of British descent with a completely boring Anglo name and history (no encounters with police, haven't moved house or changed jobs since arriving in the US, no complications in my green card process, etc.) I'm confident that my case is extremely unlikely to be delayed by FBI checks, difficulty of assembling files, etc. So, if it does take a long time for me to get an Interview Date (I was fingerprinted on 5/27), I think other Atlanta applicants will be able to conclude that scheduling of interviews at Atlanta is just slow.
