I think you do have a problem.
Prima facie, there seems to be a systemic failure @ your HR-end. When your papers are under process for H1-B, how did they accept your resignation? OR, are they bluffing?
The figure of approxly US$ 4,500/- is correct--that's the cost of every H1-B Approval, including the Attorney costs. If your HR is saying that the petition has been accepted for Processing, then you SHOULD HAVE GOT the Receipt Number--have you got it? If not, pl ask for it & cross-check the status of the Petition on-line. Here's the Link:
I am surprised HR is pointing to the Voluntary release aspect NOW.
There's also another aspect/possibility. Since the H1-B Cap for 2013 is already reached, they obviously can't file for another employee--meaning they would loose one slot [presuming they get the Approval]. COULD this be a way of holding you back?
All the Best.

#AnonymousThey have not come up with any probable solution as of today. This happened on this Friday. Immigration team has mailed the I129 form mailed to his senior for clearance on 10th May 2013. Before this, a system generated mail stating the case acceptance was sent to me after my resignation. I want to go for higher education and I have got it in one of the best B schools and cannot afford to lose this offer. Please suggest probable solution out of this...
