Doyour best to find a good lawyer
I think I had a strong case of NIW. I have 30 publications, one natinal reward from my homecountry. I have been working on the projects funded by National Science Foundation and National Institutes of Health at the leading universities like Johns Hopkins, and I provided a lot more materials than usual (for example, I had 12 reference letters from Scientists at EPA, NASA, Johns Hopkins, Georgia Tech, etc). However, my current lawyer still could not help me to get it through. My case was still denied after the request for extra evdence. The reason is: the evdence fails to show the national interests would be adversly affected if the bebeficiary were required a labor certification.
My suggestion is: do your best to find a good lawyer.
