Still have not heard anything

[GetMeAGreenCard]

I had my AOS interview in December at the Arlington Office. At that time they needed some missing paperwork. Well, I submitted the missing paperwork in Jan. I still have not heard anything.
I was wondering does anyone know how long does this additional process take. I am getting extremly worried.
Can anyone advice on what can I do to figure out what is going on here.
