What is the significance of EB preference categories?
All individuals sponsored by employers are in one of the employment-based (EB) preference categories. A person’s preference category is determined by the employment position offered, documentation of the credentials qualifying him or her for the position, and the type of case filed for that individual (based on the position’s requirements and his or her qualifications). They are called “preference” categories, because the visa numbers made available to the “higher” preference categories can “spill down” to the “lower” preference categories if they are unused.
