Regarding Request for evidence


I got my RFE on June 14 and it is almost 71 days and the status haven’t changed yet.

I called to my employer and asked about RFE he told it is about client letter and not to worry about the RFE he wil take care

But from 71 days status has not changed.

My question is how long does USCIS take to update RFE response and what are the chances of getting approval?

Thanks in advance!!!
