The primary differences between the EB-2 and EB-3 visas are related to the qualifications and requirements. The EB-2 visa is for professionals with advanced degrees (beyond a bachelor's degree) or persons with exceptional ability in the sciences, arts, or business. The EB-3 visa is for skilled workers, professionals holding a bachelor's degree, and unskilled workers (other workers). The demand, processing times, and availability of visas can also vary between these two categories.
