Any experiences of a time line for naturalization interview?


Registered Users (C)
I was wondering if anyone has experience what the time line to get the interview?

My friend applied for naturalization in November and has the biometrics appointment this upcoming week and the green card was given in February 2010 which makes February 2015 the 5 year mark to become a citizen.

Does anyone has experience if the interview will be in the same month of the 5 year mark, sooner or will it take longer?

Any experience is welcome and thanks in advance.
