Information on H1B expired petition

My petition is approved in 2015 and this is approved for 1 year i.e. till Dec 2016. I went for visa stamping from Company A and which is valid till Dec 2016.

Now both my petition and visa got expired (Not travel to US any time before expiration of Visa).

In this case can I transfer my H1B to other employer and again if I go to visa stamping can i get visa stamped or do I face any issues to get visa stamped.

Can you please help me on this?

Yes, you can transfer and get it stamped. You wont go under lottery too.

Thanks Ramana… do I get any questions while stamping and wht type questions they can ask…
