My PD was 1/11/07, EB1-b, concourrently filed I-140 and I-485 at NSC. FP was done in March 8, 2007. I-140 was approved on April 18, 2007 via express process. My hu*****and filed his I-485 in June of 2007. After I-485 pending 180days, I changed job to another location. No updates before approval except for chang address. All family members were approved at the same day on 2/12/08.
Went to local Infopass and NC was pending at middle of December. Called USCIS three weeks ago and the nice lady told me that she would send a request to the NSC because my PD was far ahead of current process time. I did not know if this helped or not.
I have learnd a lot from here. Thank everyone and good luck to everyone!!
