If your employment would be in the national interest of the United States, you may apply for a national interest waiver (NIW) as a part of your EB-2 petition. Holders of EB-2 NIW visas are regarded as U.S permanent residents.
Those seeking a national interest waiver are requesting that the job offer, and thus the labor certification, be waived because it is in the interest of the United States. The endeavors that qualify for a national interest waiver are not defined by statute; instead, USCIS considers the 3 factors below.** Those seeking a national interest waiver may self-petition (they do not need an employer to sponsor them).
a) The proposed endeavor has both substantial merit and national importance.
b) You are well positioned to advance the proposed endeavor.
c) On balance, it would be beneficial to the United States to waive the requirements of a job offer, and thus the labor certification.
