About RFE
RFE : Request for additional Evidence
Usually when the INS has any questions regarding the petition they first send out a RFE and depending on the response they approve or deny the case.
Most times the denials are due to application in the wrong catogory.
ie EB2 or EB 3 many times BS + 5 can be filed as EB2 but if not documented well... the INS may decline and ask to reapply under EB3.
RFE\'s are usually for : Educatinal Evaluation,Company financials,proof that benificiary is elgible for EB2 .and stuff like that
