I received my RFE on Dec 11, 2017 and it was responded on Jan 19, 2018, no update yet (its been over 41 days).
Since @koldrink mentioned he heard from USCIS after raising SRs stating they'll take the decision in 60 days ... is that the duration/time span for USCIS to respond or take a decision on the case after receiving the response to RFEs....?
