U.S. Citizenship and Immigration Services is extending certain COVID-19-related flexibilities through Jan. 24, 2023, to assist applicants, petitioners, and requestors.
Under these flexibilities, USCIS considers a response received within 60 calendar days after the due date set forth in the following requests or notices before taking any action, if the request or notice was issued between March 1, 2020, and Jan. 24, 2023, inclusive:
Requests for Evidence;

Notices of Intent to Deny;
Notices of Intent to Revoke;
Notices of Intent to Rescind;
Notices of Intent to Terminate regional centers;
Notices of Intent to Withdraw Temporary Protected Status; and
Motions to Reopen an N-400 Pursuant to 8 CFR 335.5, Receipt of Derogatory Information After Grant.
In addition, USCIS will consider a Form I-290B, Notice of Appeal or Motion, or a Form N-336, Request for a Hearing on a Decision in Naturalization Proceedings (Under Section 336 of the INA), if:
The form was filed up to 90 calendar days from the issuance of a decision we made; and
We made that decision between Nov. 1, 2021, and Jan. 24, 2023, inclusive.
As a reminder, the reproduced signature flexibility announced in March 2020 became permanent policy on July 25, 2022.
