Hi, im new here. I filed n400 last june 2016 for my brother(I got my citizenship one April 2015 NBC). He still waiting for 6 months now. I have check processing time and i notice something odd. Last month, St. Louis field office said case process cases as of date: April 4 2016(Last update November 2016). On January 1st 2017, I check again and it said: case process cases as of date: January 29, 2016. It kinda odd for me. When I did my citizenship, the whole process took only 4 months. I try to call them, info pass and they said I have to wait. Not thing else I can do.
