I think now a days, if we are filing a complaint and if we have something important that is getting delayd because of the adjudication of the n-400 apllication or not getting a green card, or AOS such as employment, sponsership of immidiate relative, green card expairation, or any such a thing, it is very very important that we mention it in the complaint, and NOT just mention it, but send all the proofs that we have and tell the judge that these are the main reasons why USCIS and FBI need to do their job and make a decision on this case.
Offcourse, each judge is different, but my point is that you are NOT just including this thing to convince the judge, but to convince the AUSA, indeed, so he can start working on your case. It is because we should remember that AUSA may have 50/60 cases assigned to him/her and she/he may not have enough time to go through each of them and if you can convince AUSA that you really have a problem, he may remember your case and do his job instead of telling you that USCIS is not requesting FBI to expediate anymore.
I am NOT saying that this method will always work, but we have nothing to loose. Please post any comments you have on this. Good luck to all of us, regards, dude
