What Form I-765 is
uscis.gov says certain aliens who are in the United States may file Form I-765, Application for Employment Authorization, to request an Employment Authorization Document (EAD). Other aliens whose immigration status authorizes them to work without restrictions may also use Form I-765 to apply for an EAD that shows such authorization. Whether you can file, and under which category, is decided by USCIS rules, not by this page: read the Form I-765 instructions and the USCIS page.
