<b>Here is my Situation.</b><p>

I used to work for Employer "A" who filed for my EB3 Labor and I-140. I-140 was approved in Feb 2007. In July 2007, when the dates became current, I filed for my I-485. In December ending of 2007, which was around 180 days after filing the I-485, Company "A" was acquired by Company "B", at that time I got an email from my employer HR indicating that Company "B" will now take over all immigration responsibilities of "A" and no H1 transfers or re-filing of I-140 is required. I was also assured that since my I-485 was pending for 180 days and i had EAD and 6 pay slips / one per each month from company "A" , there should not be
any issues, since AC21 can be applied too, in this case. So I continued to work for Company "B" for about 1 year from Jan 2008 to Jan 2009. I received pay checks from "B" during this period.

In Feb 2009 I joined a direct client, Company "C" on H1B. Got the H1B approval beyond 6 years, using company "A" I-140 approval copy. Company "C" Attorney sent AC-21 documents to USCIS. Company "C" does not file labor or I-140 they do only H1B or hire on EADs but does not do green cards. Now, after more than 7 years of I-140 Approval from Company "A", I came to know that USCIS, has revoked the I-140 of a different employee who was in the similar situation as me, but he didn't had H1B and he was forced to leave USA since his I-485, EAD and Advance Parole were all based on this I-140. It seems USCIS said the underlying Labor and I-140 were fraud. Hence everything is denied. He did leave the country.

<b>My Question : </b>
What are my Options if something like this occurs for my case too? I understand its hard to tell if this will occur or not. Company "A" which filed my I-140 no longer exists and I have no contact what so ever with Company "B". If I-140 gets revoked for fraud by the company "A", will the employee be held responsible? Can this kind of adverse decision be appealed and during appeal process what happens to the status.
Are we allowed to stay and work in the country when this case is in progress? I was reading online about the "The case, Kurapati vs USCIS”, this lawsuit is similar in nature. Is there a ray of hope with this? <p>You’re Suggestions/Comments please.
