I got green Card on March 29,2012.Many thanks for 863211, PJiang, Xiaobaitu, two cents,Radiology. All of you guys provided me great helps.
I began my PERM on 02/13/2007.The company promised me to sponsor EB2. However, after one and halfe years, when I got I-140 approval notice, I found my I-140 is EB3.
In 2010, I changed company, the new company sponsored me EB2. Since my original PERM documents were lost by Attornet, it took me 11 months to get I-140 approved( normally 4 months)
I am happy although it took over five years to get my Green Card.
Good luck to everybody !
