There are several government agencies involved with granting permission for foreign workers to work in the United States. First, employers must seek certification through the U.S. Department of Labor. Below you will find a link to documents and forms. Once the application is certified/approved, the employer must petition the U.S. Citizen and Immigration Services for a visa. Approval by the Department of Labor does not guarantee a visa issuance. Applicants must also establish that they are admissible to the U.S. under provisions of the Foreign Labor Certification - Foreign labor certification programs are generally designed to assure that the admission of foreign workers to work in the United States on a permanent or temporary basis will not adversely affect the job opportunities, wages and working conditions of American workers.
Documents and Forms - Here you will find forms to download, including the Application for H-1B Nonimmigrants (form ETA-9035), the Application for Alien Employment Certification (form ETA-750A), the Application for Alien Employment Certification (form ETA-750B), and the Application for Alien Employment Certification for Agricultural services (form ETA-790).
