If I may verify the processing times involved in NIW. Since it falls under EB2 category, I am assuming it may be a long time before I can get my EAD card and be able to change employers. Also, I want to confirm if there could be issues if I change employers during the process - If so, I'd prefer to change my current employer before starting with it.
You can change employers any time if you are a self-applicant and will continue to work in your stated area of national interest. But NIW priority date will take the same time as a normal EB-2 application does. See:

1) How long does one have to wait in total if the company applied for PERM (EB2 - MS CS degree), and THEN Concurrently applied for I-140 (premium) and I-485 and the country of birth is UAE?
2) Can the above be done on an F-1 (OPT + STEM OPT) Visa instead of an H-1B? And any potential issues for F-1 in this case?
3) In this scenario, how would it work if the person also submits NIW in parallel with PERM?
