Pardon my ignorance but why do you need to leave the US again?

Based on my limited understanding - if you already have a EB-2 petition approved, you should be able to continue working on H1 as long as your employer is sponsoring you unless you're moving out of frustration due to long wait times.

To do that I would need to take up a job at some big tech firm.

If someone in my situation is forced to do shut down his startup and work for a big firm to stay in US, imagine how difficult it would be for someone else to decide to quit their job to do a startup!

I think big companies have played this well!
