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:

I contacted immigration.com., and got an email back the next day, and phone consult set up with Rajiv Khanna two days later. He was extremely helpful, explaining to me the weaknesses and opportunities of my case, and actually gave me some reference point to talk to my employer. I am grateful to Rajiv and his staff for their assistance, and would wholeheartedly recommend them to anyone looking for quality legal opinion on their immigration cases.
