I got valid petition from Employer A in 2008 , it was valid till 2011. I never travelled to USA on this petition and VISA was not even stamped.
Now I am on H4 visa, planning to apply for H1B. Am I considered in H1B cap exempt.
1> As my visa was not stamped , am I eligible for cap exempt
2>Can other sponsor apply for H1b cap exempt
3>What is maximum duration I have to apply for cap exempt
