- Getting started
To be considered for an immigrant visa under some of the employment-based categories, the applicant’s prospective employer or agent must first obtain a labor certification approval from the Department of Labor. Once received (if required), the employer then files an Immigrant Petition for Alien Worker, Form I-140, with the U.S. Citizenship and Immigration Services (USCIS) for the appropriate employment-based preference category. (NOTE: Persons with extraordinary abilities in the Employment First preference category are able to file their own petitions.) When filing the Immigrant Petition for Alien Worker, Form I-140, see the detailed form instructions, as well as more detailed requirements information on the USCIS Permanent Workers webpage.
