From USCIS:
In response to the Coronavirus (COVID-19) pandemic, U.S. Citizenship and Immigration Services announced that it adopted measures to assist applicants and petitioners who are responding to certain Requests for Evidence (RFE) and Notices of Intent to Deny (NOID). This alert clarifies that this flexibility also applies to certain Notices of Intent to Revoke (NOIR) and Notices of Intent to Terminate (NOIT) regional investment centers, as well as certain filing date requirements for Form I-290B, Notice of Appeal or Motion.
Notice/Request/Decision Issuance Date:
This flexibility applies to an RFE, NOID, NOIR, NOIT or appealable decision within AAO jurisdiction and the issuance date listed on the request, notice or decision is between March 1, 2020 and May 1, 2020, inclusive.
Response Due Date:
Any response to an RFE, NOID, NOIR, or NOIT received within 60 calendar days after the response due date set in the request or notice will be considered by USCIS before any action is taken. Any Form I-290B received up to 60 calendar days from the date of the decision will be considered by USCIS before it takes any action.
USCIS is adopting several measures to protect our workforce and community, and to minimize the immigration consequences for those seeking immigration benefits during this time.
USCIS will provide further updates as the situation develops and will continue to follow CDC guidance. Education and precautions are the strongest tools against COVID-19 infection. Please visit uscis.gov/coronavirus for latest facts and other USCIS updates.
