EAD and U.S. Work Authorization
It is mandatory for all U.S. employers to ensure that their employees, regardless of citizenship or national origin, are allowed to work in the United States, consistent with the terms of their employment. An Employment Authorization Document (EAD) is a work permit that authorizes an individual to work in the United States. The EAD is issued by the United States Citizenship and Immigration Services (USCIS) in the form of a small card.
