A First Preference applicant must be the beneficiary of an approved Immigrant Petition for Foreign Worker, Form I-140, filed with USCIS. Labor certification is not required for any of the Priority Worker subgroups. Priority Workers receive 28.6 percent of the yearly worldwide limit of employment-based immigrant visas.

There are three sub-groups within this category:

1. Persons with extraordinary ability in the sciences, arts, education, business, or athletics. Applicants in this category must have extensive documentation showing sustained national or international acclaim and recognition in their fields of expertise. Such applicants do not have to have specific job offers, so long as they are entering the U.S. to continue work in the fields in which they have extraordinary ability. Such applicants can file their own Immigrant Petitions for Alien Worker, Form I-140, with the USCIS.
2. Outstanding professors and researchers with at least three years experience in teaching or research, who are recognized internationally. Applicants in this category must be coming to the U.S. to pursue tenure, tenure track teaching, or a comparable research position at a university or other institution of higher education. The prospective employer must provide a job offer and file an Immigrant Petition for Alien Worker, Form I-140, with the USCIS.
3. Multinational managers or executives who have been employed for at least one of the three preceding years by the overseas affiliate, parent, subsidiary, or branch of the U.S. employer. The applicant’s employment outside of the U.S. must have been in a managerial or executive capacity, and the applicant must be coming to work in a managerial or executive capacity. The prospective employer must provide a job offer and file an Immigrant Petition for Alien Worker, Form I-140, with the USCIS.
