1) What if Company A, out of the blue, sends in a 140 revocation 18 mos after I left them and
dfagen19:
Read INS AC21 June Memo (search goggle), if your employer tries to revoke your I-140 after 180 days then you may be able to receive GC and continue GC process. This is according to Sheela Murthy, she said many times in her chat that if I-140 is revoked after 180 days of pending I-485, then this is OK case to use AC21 and she posted that INS (BCIS) H.Q told verbally that revocation of I-140 after pending I-485 more than 180 days will have no bad affect on GC (read Murthy Chat)
2) If they go out of business or someone else buys them, can the new owner decide to revoke all existing I140's??
If they go out of business no problem for you, if the new company takes over everything than they may try to revoke but you have crossed 180 days, I don’t think it will have any bad affect on your future GC
Please remember still no final regulations regarding AC21 have been published, every lawyer tries to interpret the AC21 law according to different trends of AC21 cases being processed in different service centers. No body can give you a final answer, due to Lack of AC21 Final Regulations.

atanu : I changed job after 180 days of I-485 and my old company has proceeded to revoke the I-140. Do I need to take any proactive action now to protect my I-485?
SPEAKER_Attorney_Murthy : If the I-140 petition is revoked, then the I-485 will likely be denied by the INS. It is not clear if the employer can legally revoke the I-140 under the AC21 law but under prior law that was clearly permissible. The way to protect the I-485 is to file a new LC and a new I-140 and then try and substitute it with the new I-140 in the pending I-485.
