Here is my timeline,
I-140 PD Sept. 5, 2005
I-140 AD Sept. 19, 2005
I-485 PD Sept. 25, 2005
Finger print Nov. 2005/code 3, Feb. 2007/code 1.
Infopass on May 1 knew NC cleared on Apr. 2007.
I-485 Approved and card production ordered on June. 26, 2007, informed by email. This case was ted to NSC and stayed there all the time.
Hope this is the end of the painful journey. I want to thank for all the useful information and kind suggestions that I get from this forum. I didnot hire lawyer for NIW application. During my DIY process, I found this forum and immigration forum quite helpful. While the endless waiting for the visa quota, I hired a lawyer and did LC subtitute (both I-140 and 485 ted) at the end of last year. Now it seems that LC subtitute is a waste in my case, but it proves that two I-485 application is allowed.
Lastly, special thank to Xiao Bai Tu, my two cents, Radiology and other experts for their selfless help and time. Wish Everyone best luck and get the green card soon!
