so the guy asked coupla questions, big deal ...
In my opinion ...
I think it will be lil faster in Atlanta now, especially when they doing interview and oath at the same day. Also, it used to take around 14 months as an average, i think they brought it down to 12 just in last 4/5 months. if they keep doing this for another 6 months and you are Feb, expect something in Nov/Dec timeframe.
Good luck!!
