SEP2009 filers
I think this is a mess here as to where to post tracking. I found people tracking based on citites, USCIS offices, quarters, months, etc.
From what I read, all N-400 cases are handled in NBC, then sent to local office for interview. Therefore, there is no meaning tracking based on local office until interview.
Quarter based / Month based makes more sense.
I finally decided to put my tracking info under SEP2009
