This document provides information about employment-based green card acquisition from the Buhler Law Office. It outlines the four types of employment-based green card applicants and the five categories of immigrant workers according to the USCIS. These categories include priority workers, persons with exceptional ability, professionals/skilled/unskilled workers, special immigrants, and investors/employers. While many strive to obtain a green card, it is a rigorous process with only a small fraction of applications approved each year.
