U.S. employers must check to make sure all employees, regardless of citizenship or national origin, are allowed to work in the United States. If you are not a citizen or a lawful permanent resident, you may need to apply for an Employment Authorization Document (EAD) to prove you may work in the United States.
USCIS issues Employment Authorization Documents (EAD) in the following categories:
1. EAD: This document proves you are allowed to work in the United States.
2. Renewal EAD: You cannot file for a renewal EAD more than 120 days before your original EAD expires.
3. Replacement EAD: This document replaces a lost, stolen, or mutilated EAD. A replacement EAD also replaces an EAD
that was issued with incorrect information, such as a misspelled name.
