H1b background check

Hi All,My H1b is picked in lottery. I have a small doubt.My doubt is will USCIS do any previous employment background before Approving my Case. I have total IT experience of & years, but the company i have worked for first three years dose not exist now.Can any one please also let me know the process after H1b case is picked in lottery.

I dont think so… Usually USCIS care only about your future project and your potetials…

If the work you did is real, does not matter if the company has gone away. I would not worry.
