The EB-1 and EB-2 visas are both employment-based immigrant visas that allow foreign nationals to obtain U.S. permanent residency (green card). The key difference lies in eligibility. The EB-1 visa is for individuals with extraordinary ability in the sciences, arts, education, business, or athletics, as well as outstanding professors, researchers, and certain multinational executives. The EB-2 visa, on the other hand, is for professionals with advanced degrees or individuals with exceptional ability in their field. In general, EB-1 applicants face higher eligibility standards but often benefit from faster processing times, while EB-2 applicants have broader eligibility but usually longer wait times.
