ALIENS WITH EXTRAORDINARY ABILITY are those with "extraordinary ability in the sciences, arts, education, business, or athletics which has been demonstrated by sustained national or international acclaim and whose achievements have been recognized in the field through extensive documentation." These individuals must be one of "that small percentage who have risen to the very top of the field of endeavor," to be granted this classification. For example, receipt of a major internationally recognized award, such as a Nobel Prize, will qualify for an EB-1 classification. Other awards may also qualify if can be documented that the award is in the same class as a Nobel Prize. Since few workers receive this type of award, alternative evidence of EB-1 classification based on at least three of the types of evidence outlined below, is permitted. The worker may submit "other comparable evidence" if the following criteria do not apply:

2. Membership in associations in the field which demand outstanding achievement of their members;
3. Published material about the alien in professional or major trade publications or other major media;

7. Evidence that the alien's work has been displayed at artistic exhibitions or showcases;Performance of a leading or critical role in distinguished organizations;
8. Evidence that the alien commands a high salary or other significantly high remuneration in relation to others in the field;
9. Evidence of commercial successes in the performing arts.

In addition, an outstanding professor or researcher must have at least three years experience in teaching or research in that academic area, and enter the U.S. in a tenured or tenure track teaching or comparable research position at a university or other institution of higher education.

Evidence that the professor or researcher is recognized as outstanding in the academic field must include documentation of at least two of the following:

National Interest Waiver:
Aliens seeking a national interest waiver are requesting that the Labor Certification be waived because it is in the interest of the United States. Though the jobs that qualify for a national interest waiver are not defined by statute, national interest waivers are usually granted to those who have exceptional ability (see above) and whose employment in the United States would greatly benefit the nation. Those seeking a national interest waiver may self-petition (they do not need an employer to sponsor them) and may file their labor certification directly with USCIS along with their Form I-140, Petition for Alien Worker. The individual must meet at least three of the criteria included under exceptional ability above and demonstrate that it is in the national interest that they work permanently in the United States.
