The Outstanding Researchers and Professors EB-1 Subcategory

If a foreign national has an international reputation for being outstanding in a particular academic field, that person may, with an offer of work from a U.S. employer, qualify for a Green Card as a priority worker within the outstanding professors and researchers subcategory. The foreign national will have to show at least three years experience at either teaching or research in the relevant academic field. 

The job offer for which the applicant is coming to the U.S. must be a specific tenured or tenure-track teaching or research position at a university or an institution of higher learning. Or, if the position is at a research organization, it must be a permanent position - showing permanence can be a bit dicey in cases where the position is based on grant money that will run out in a year, but this can be overcome by showing that the employer intends to seek continued funding and that a reasonable expectation of success exists, such as a track record of renewed funding.

Not every type of employer can make use of this visa category. It must be a qualified employer, meaning either a university or institution of higher education or a department, division, or institute of a private research entity with at least three full-time researchers on staff. The private U.S. employer will also need to show a history of making significant achievements in research.
