EB-3(A): This category is for 'professional workers' with a U.S. bachelor's or foreign equivalent degree and with a job offer from a U.S. company

Professionals must hold a US baccalaureate degree or foreign equivalent degree that is normally required for the profession. Education and experience may not be substituted for the degree.
Skilled worker positions are not seasonal or temporary and require at least two years of experience or training. The training requirement may be met through relevant post-secondary education. The Labor Certification Form states the job requirements, which determine whether a job is skilled or unskilled.
Other workers are in positions that require less than two years of higher education, training, or experience, such as an unskilled worker who can perform labor for which qualified workers are not available in the United States. However, due to the long backlog, a petitioner could expect to wait many years before being granted a visa under this category.
