My employer applied for H1b Visa and i got approved H1B petition in 2013 which was valid from Oct 2013 to Sept 2016 (3 years). My passport was never stamped with the Visa and nor i traveled to USA. The only thing i have at present is the receipt number and the approved petition (I-797) which already got expired in Sept, 2016. My question is if i will search another employer now who is ready to file H1B transfer, can i be counted in cap exempt and can i use the same receipt to do H1B transfer to another employer in cap exempt category. Please reply.
