6 year H1 expired+PERM approved+I-140 Not filed: H1 extension by a different company ?

[SriSai_raj]

My six year H1B visa expired in 2012, and I left the US. My company (A) applied for my PERM only after I left the US. This got approved 2013. But my company say that they cannot (won’t) file I-140 or extend my H1 visa. So, I am considering changing to a different employer. I’ve the following questions.

 

1. Can a different company (B) extend my H1 based on the approved PERM by company A?
2. If a new H1 is filed (not an extension)? Is it subject to cap, given the fact that I’ve been outside the US for more than a year?
3. Please suggest any ways for me to get back to US on work visa?

Experts! please help! my PERM is going to expire in 15 days.
