U.S. Citizenship and Immigration Services announced on July 1, 2020 that due to COVID-19, it is providing 60 additional days to act in response to evidentiary requests or certain notices or decisions, if those agency actions were issued between March 1, 2020 and September 11, 2020.
With USCIS now saying it will be furloughing about 75% of its workforce as of August 3, 2020 due to budget shortfalls, its ability to respond to responses and appeals filed by those who have applications for residency, citizenship among others, will be greatly diminished in any case, causing even longer delays than at present.
