From USCIS:
U.S. Citizenship and Immigration Services today announced that it will reuse previously submitted biometrics in order to process valid Form I-765, Application for Employment Authorization, extension requests due to the temporary closure of Application Support Centers (ASC) to the public in response to the coronavirus (COVID-19) pandemic. This announcement is consistent with existing USCIS authorities regarding the agency’s ability to reuse previously submitted biometrics.
Applicants who had an appointment scheduled with an ASC on or after the March 18 closure or has filed an I-765 extension will have their application processed using previously submitted biometrics. This will remain in effect until ASCs are open for appointments to the public.
