What is an Employment Authorization Document (EAD)?
An Employment Authorization Document (EAD), commonly called a work permit, is a card issued by U.S. Citizenship and Immigration Services (USCIS) showing that you are allowed to work in the United States for a set period. You apply for it — and later renew it — using Form I-765, Application for Employment Authorization. The card shows an expiration date on its face, which is the date this tool uses to figure out your renewal window.
