I know a girl who`s whole process from sending N-400, biometrics, and interview took only a month. I sent my N-400 in December of 2006, and haven`t taken biometrics yet. Just wondering how others doing (or have done) in this process.

It all depends on numerous factors, where you live, how your name check is going etc. Mine took about a month and a half or so if that, but others have taken a lot longer. Generally the delay means you're still stuck in the name check...
