Many types of workers can try to apply for permanent status based on their employment and this includes skilled and unskilled workers, international organization employees, religious workers, individuals with advanced degrees that could benefit the U.S., outstanding professors and researchers, and other workers. As long as you can prove that your educational background or work experience could be an asset to the United States and there are no qualified U.S. workers to fill your position, you have high chances of getting an employment green card.
