Thanks LC_Virginia. Gook luck to your I485.
msd_gc,
I don't know the reason of delay. No RFE, No LUD change since Jan29th, the lawyer did call CIS 1-800 number to initiate an inquiry back in Sept, no response for the call. Company is financially sound, should not cause delay. I guess it is the sub labor, it stated 3yr Computer Science related experiences and a CS Master degree. I was non CS major as an undergraduate, working for 3 and 1/2 yrs in non CS field. Then I got a M.S. is CS. My working experience is arguably CS related. Also the job title is different of my H1B with the sub labor, the lawyer did attach a letter to explain that with the application.
Good luck to all of you.
