EB-2 visa
EB-2 is an immigrant visa preference category for United States employment-based permanent residency, created by the Immigration Act of 1990. The category includes "members of the professions holding advanced degrees or their equivalent", and "individuals who because of their exceptional ability in the sciences, arts, or business will substantially benefit prospectively the national economy, cultural or educational interests, or welfare of the United States, and whose services in the sciences, arts, professions, or business are sought by an employer in the United States". Applicants (with the exception of applicants applying for an exemption known as National Interest Waiver) must generally have an approved Permanent Labor Certification, a job offer, and their employer must have filed an Immigrant Petition for Alien Worker (Form I-140) with the USCIS.
