H1B tansfer using old employer I 140

[snayabu]

Hi,

I have an I-140 application approved from Company A and currently working for company B where my GC process has not been initiated yet.

I got a better opportunity and planning to move to Company C.

Can I use Company A's approved I-140 to get 3 years H1B Transfer and extension while working with Company B where GC isn't initiated yer

I am in my 6th year of H1b

Thanks
