Different H1B holder and Different GC sponsor

[Maxe_25]

Hi Friends,

I am working for company A on H1B since 2 years.
This Company A is IT service provider company.
Since last 1 Year I am working for Client through my company A.

Now consider client as company B.
Company B now ready to transfer H1B, but only for 2 years of limited time.

Now, Can I join Company B for 2 years and have Company A filed my GC.
Once my 2 years time is completed at Company B, I am planning to again join Company A.

I appreciate all your input on this.

You can do that provided Company A has buy in to the idea. GC is for future employment.
