Example EAD cards from 2017 (left) and 2011 (right)

A Form I-766 employment authorization document (EAD; [1]) or EAD card, known popularly as a work permit, is a document issued by the United States Citizenship and Immigration Services (USCIS) that provides temporary employment authorization to noncitizens in the United States.

Currently the Form I-766 Employment Authorization Document is issued in the form of a standard credit card-size plastic card enhanced with multiple security features. The card contains some basic information about the immigrant: name, birth date, sex, immigrant category, country of birth, photo, immigrant registration number (also called "A-number"), card number, restrictive terms and conditions, and dates of validity. This document, however, should not be confused with the green card.
