I was in the US on L1B until June 2013. Completed 5 years of my stay in US. Filed H1 in April 2013. Through RFE my H1 got approved and received the approval in Dec 2013. The petition was valid till Dec 2015. (Valid for 2 years) (I was expecting the petition valid only for a year. Does this mean my clock got reset and I can work in the US for the next 6 years?
