40 validity after change in employer

[bejoy7770]

I have my I140 approved thru employer A. I went on vacation to India and didn't get my visa stamped. I got back to the US with a new H1B thru a new employer B (with in 6 months). Employer A is very helpful and employer B is not interested in me other than for the current project.

Is my I140 valid, if I jump back to employer A?

I have the following option:

a. Employer A is waiting for papers from USCIS to file an appeal.

b. If option a is not successful, I can try to transfer my H1B to employer A.

c. Or I can try to get a new visa thru employer A.

My priority date is March 2009 (on EB2) and my current visa is (and last visa was) valid till Sept 2012.

Your thoughts..
