PD of my I485 is 06/30/05, and still pending. I visited info and called uscis many times. Also i quested inquiry several times as well, and they kept saying that the case is pending, and take 6 month to process. I called IO again yesterday to ask about inquiry that why i got same answers, and my case is still pending? He said that "Be patient! Work load is heavy". Do you have an idea to speed up? Thank you very much!
