NOF is issued when there is a correction to an already scrutinized application.It means the application can be corrected for immediate approval. Whereas in the case of REF,DOL is expecting additional evidence to approve the LCA.In case of REF it may result in rejection also.In case of NOF there may not be a rejection. NOF is a common querry in most of the cases.In most of the cases even if there is any correction in the application,there will be NOF but not RFE.
