Information for Employers and Employees
Employers must verify that an individual whom they plan to employ or continue to employ in the United States is authorized to accept employment in the United States. For more information about the employment authorization verification process, see the “I-9 Central” page.
As an employer, you may require the services of an alien to work at your company or business. If the individual is already a permanent resident (green card holder), you may hire that individual, but you must comply with the employment verification requirements.
If the alien is not already a permanent resident, you will need to file a petition so that the individual may obtain the appropriate immigrant or nonimmigrant classification. You may choose to file an immigrant petition (permanent) or a nonimmigrant petition (temporary) on behalf of that employee. The links to the left provide information on how to petition and the different eligibility categories.
No alien may accept employment in the United States unless they have been authorized to do so. Some aliens, such as those who have been admitted as permanent residents, granted asylum or refugee status, or admitted in work-related nonimmigrant classifications, may have employment authorization as a direct result of their immigration status. Other aliens may need to apply individually for employment authorization.
There are many ways in which a person may be able to work in the United States. You may seek an immigration classification that permits you to live and work in the United States permanently or temporarily. In most instances, your employer or potential employer must petition for you. In the links to your left, you will find more information about coming to the United States to work temporarily or permanently and the many different eligibility categories for working in the United States.
