緊急求助小白兔和其它大俠: 我該怎麽辦?

I filed the I-485 petitions in 2002 that are still pending. So I filed a Complaint against the USCIS and FBI in this Feb. Now I have received a notice from the Court which says that “ the Court possesses the authority to dismiss this action on the basis of the defendant’s motion if you do not file a response. If the Court dismisses this action or enters judgment for the defendant, the case will be concluded and the Court will have decided this case against the plaintiff”.
I want to know the consequence if I did not file a response, and what can the Court do against me. If can my hu*****and and my son get their GC separately (they depend on me). The worst thing is the I just got lay off on last Friday.
I have been totally frustrated. I am in hot water. Please give me two cents.
Thank you very much!
