I completed MBA from Cornell University in May 2017 and worked in US on OPT until Jan' 2018. I traveled to India in Jan' 2018 and my H1B petition was approved when I was in India. I subsequently went to US consulate in India and got H1B stamped on my passport. It is valid for 3 years from Feb' 2018. Immediatelty after the H1B stamping on my passport, my employer in US fired me saying that there currently is no job requirement in the company. I could not travel back to US after H1B stamping.
