My employee’s Form I-766, Employment Authorization Document (EAD), is about to expire and they do not have a new one. Could their EAD have been automatically extended?

DHS sometimes issues an automatic extension of EADs for certain individuals. See the USCIS Automatic EAD Extension page and Section 4.4 of the Handbook for Employers: Guidance for Completing Form I-9 (M-274) for detailed information on EADs that can be automatically extended. The USCIS Contact Center can help with questions about a specific individual.
