H4 visa got 221g blue slip at Chennai - How Long Processing?

H4 visa 12th Nov 2019, got 221g blue slip at Chennai location asking for more documents to be emailed regarding previous stay in the US. I emailed them all the documents the same day. Any idea on processing time?

221g is like a black box, no one really knows how long it can take…It can take anywhere from few days to few months…Stay positive…As it is H4, should be quick…See others info and add yours at the tracker 221g Tracker
