Reg. H1b Cap process

[elumalai.suganthi]

Hi ,

I had H1B visa with my previous employer for the duration 2007 to may 2010, and it got expired.
I also travelled with the same H1B when it was active with my previous employer.

Now i am trying for H1B cap for it, but my badluck is i dont have my H1b petition hard /soft copy,
my previous employer is saying, they have not maintaining any copy of it with them.

I want to know few things like,

1. Am i eligible for H1B Cap now?
2. Is there a way to apply for H1B cap without a petition copy?
3. Will US embassy help me to get my H1b petition copy?
4. is there any other way around to transfer the h1b to my current employer to do the H1b cap process?

Thanks & Regards,
Suganthi
