Form I-766. Employment Authorization Document (EAD)

Form I-766 is the Employment Authorization Document (EAD), which is a document that proves an individual's eligibility to work in the United States. It is commonly referred to as a work permit.
The EAD is issued by the United States Citizenship and Immigration Services (USCIS) to individuals who are authorized to work in the United States for a specific period of time. This document is typically issued to non-U.S. citizens who are in the process of adjusting their immigration status or who have been granted temporary permission to remain in the United States.
