Immigrants require employment authorization to lawfully work in US.

[nancymervin]

Certain aliens who are temporarily in the United States may file a Form I-765, Application for Employment Authorization, to request an Employment Authorization Document (EAD). Other aliens who are authorized to work in the United States without restrictions should also use this form to apply for a document evidencing such authorization.

When a foreign national successfully completes an application for employment authorization with Form I-765, and obtains an employment authorization document (EAD), he or she will be able to lawfully work in the United States for any employer.
