RFE in h1b visa - Is my visa rejected?

Got an RFE in h1b visa and i am yet to receive the details. Does this RFE indicates my visa rejection?

How many days will it take for the status change if my evidence were submitted?

RFE does not indicate your petition rejection. USCIS is trying to get more justification so that they can approve your petition. once your documents are received within a weeks time your Status changes from RFE to RFE Review. Thanks Vivek
