What is the difference between the skilled worker, professional, and other worker subgroups in EB-3?

EB-3 is a single employment-based green card preference split into three subgroups based on the requirements of the offered job. Skilled workers fill positions that require a minimum of two years of training or work experience that are not temporary or seasonal. Professionals must hold at least a U.S. bachelor's degree (or a foreign equivalent) that is the normal requirement for the profession.

The third subgroup, often called other workers or unskilled workers, covers positions that need less than two years of training or experience and are not temporary or seasonal. The other worker subgroup typically faces the longest waits because demand is high and visa numbers are limited. Which subgroup you fall into is determined by the job the employer offers, not simply by your own qualifications.
