Continued renewability of H1 based on approved I-140 from past employer

[gcneedy]

Hi All,

Need help with a question. I have an approved I140 with employer A, PD: March 2012 (country of chargeability: India) 6 yrs on H1 are over and employer A has renewed my H1, now it's valid till 2016. I got a job offer from employer B, I like the role and the salary hike, employer B will start my PERM process soon after joining. but don't want to take too much risk. So I have the following question:

1. In case due to audit or whatever reason my employer B PERM doesn't get approved by 2016 (unlikely. But assume that's the case), will I be able to get my H1b renewed again for 3 yrs based on copy of my I140 approved via employer A?

2. In case in 2014 I end up changing jobs and go to employer C, then can I still get 3 more yrs on my H1 based on the approved I140 via employer A?

3. Given my PD is 2012, do any of you see any chance of that becoming current in the next 18 months? (I know it's impossible to predict, but just asking for your gut feel)

I should also note that employer A is a large corporate and I do not expect them to withdraw my I140.

Thanks a ton for your input
