Came to US in May 2005 I worked for consulting company A.

My Client company B offered me Job on July 2007 and I worked for them till June 2010.

I have the approved I140 from Company B with a PD Nov 2008 (EB2 India.)

I got laid off from B. I got a new client and joined consulting company C.

I have the H1B extended only for a year till Oct 2011. Company C mentioned about AC21 to retain my PD when they submitted my papers for H1 Transfer.

Company C did say that they will process my green card. Company C haven't filed for Labor Certificate and I-140.

It seems that Company B has indicated that USCIS that I don't work for them anymore. I recently recieved a I 140 Intent to revoke mentioning that I dont have education requirements and asking for proof. How can I appeal this?
