The USCIS has previously announced extensions of time for applicants and petitioners to file responses to USCIS requests for evidence, denials and other notices, which extended until Jan. 1, 2021.
The newest extension announced on December 18, 2020, extends that period until Jan 31, 2021.
As a result of the new extension policy, an additional 60 calendar days from the deadline date will be given to submit a response to a request or notice issued by the USCIS from March 1st 2020 through and Jan. 31, 2021. The Biden administration is expected to provide further extensions until at least mid-2021.
The additional 60 days applies to:
Requests for Evidence;
Continuations to Request Evidence (N-14);
Notices of Intent to Deny;
Notices of Intent to Revoke;
Notices of Intent to Rescind and Notices of Intent to Terminate regional investment centers;
Form N-336, Request for a Hearing on a Decision in Naturalization Proceedings and
Filing date requirements for Form I-290B, Notice of Appeal or Motion.
It is important to note, that responses must be received on or before the deadline, not just postmarked by the deadline date. Also, responses to requests for additional evidence should always be mailed in one package, not in multiple response filings, since once the USCIS receives the first response, the officer will usually make a decision based upon that response, not on anything received later.
Finally, always send responses, appeals, motions via fed-ex or another mail service, overnight.
