green card process after returning back to India

Hi,

I have an approved EB1 I-140 with priority date in 2018. I had to return to India in 2021 due to personal reasons. Just before returning I did apply for I-485 (adjustment of status). The I-485 got approved and I also received notice for appearing for biometrics after I left US.

Now I am planning to return back to the US.

Will my I-140 priority date remain valid? I guess I need to re-apply for I-485. What will be the typical processing time?

Will the green card processing be quicker if I join my old company or I may join any other company in the same job category?

Thanks
