In 2019, I was working for Employer A. They have applied for H1B and it got picked up. I have received I-797B form stating that it is valid from 10/01/2019 to 09/09/2022. In 2021 i have changed A to B employer. My H1B is never stamped and I never travelled to US. Could you please let me know whether my H1B can be renewed and does it still fall under cap-exempt.
