H1B with I140

[msubbu1]

1. Earlier, I was on my H1 6th Year. I got my I140 approved with Company A. Used the same to move to Company B. Now (After 2 years) I am thinking to move to Company C. Can I use the I140 which I got through Company A?. I did not apply for GC through Company B & I have only one year of valid Visa.

2. How can I verify whether my I140 that Company A applied is still not revoked?.

Thanks for reading this, Your input would be a great help!.
