Filed 3/21/06 to ca center(EB2 employee based). I got my receipt number from my lawyer last week .but each time I checked my case on line .the system said there is no case information. I was so worried .but just a few minutes ago, I checked it again .it said the case was approved on Apirl 27th. So fast .I even don not know where my case was processed! amazing. I hope everyone can have such a good luck!
