Can Approved I-140/I-485 be Revoked?

[myinfo2005]

Does anyone know that a Company can revoke Approved I-140 and(or) I-485s? Once the I-485 is approved, How long a person need to be with the same company? Is there any time limit? Or can he/she leave the Company whenever he/she wants, after his/her 485 approval?

The company could. Normally companies don't. If they only want to take revenge on you. That should not affect your PR status but in the future when you apply for a replacement card, etc there might be possibility of an RFE. I would talk with a lawyer to get more info. All in all leave with the positive note from previous employer if you could.

You Mean, Company CAN Revoke approved Green Cards? Please confirm...

Any input from some experienced folks here? My question is "How long a person need to stick with the same company (GC sponsor), after his/her I-485 Approval and Stamping on his/her passport? Please include your thoughts and comments....
