Is your case stuck with NSC?
That is why I say we need to get united and ask the Ombudsman to help us by holding USCIS accountable. Please look at the NSC thread. We have received a response from the Ombudsman office and we need your cooperation to resolve this problem. Please go to the NSC thread and read Letter to Ombudsman thread.
Some members had got together and contacted Ombudsman office to make them aware about how NSC was using excuse of poor staffing and ignorance about number of files becoming current - so that they can slowly process cases. Well unless we inform the watch dogs, we can only suffer in silence or on complaining on this forum.
