The USCIS stated:
Due to the extraordinary and unprecedented COVID-19 public health emergency, the production of certain Employment Authorization Documents (Form I-766, EAD) is delayed. As a result, employees may use Form I-797, Notice of Action, with a Notice date on or after December 1, 2019 through and including August 20, 2020 informing an applicant of approval of an Application for Employment Authorization (Form I-765) as a Form I-9, Employment Eligibility Verification, List C #7 document that establishes employment authorization issued by the Department of Homeland Security pursuant to 8 C.F.R. 274a.2(b)(1)(v)(C)(7), even though the Notice states it is not evidence of employment authorization. Employees may present their Form I-797 Notice of Action showing approval of their I-765 application as a list C document for Form I-9 compliance until December 1, 2020.
