Fresh H1B petition approved, but not stamped. Can it be transferred to Employer B and stamped through them.? What are the complications with this proc

Hi There,

I have a Fresh H1B petition approved, but not stamped. I have an offer from a new employer B and will be joining them shortly. So wanted to know if my H1B petition can be transferred to Employer B and stamped through them.? What are the complications with this process? Is there a time frame it needs to be done? If this is missed, do i need to go through the lottery process the next time again?

Thanks in advance.

Thanks Nitin for your quick response…!! Very much appreciated…!!
