A desk review is a compliance assistance tool that consists of phone calls and emails between M&C and E-Verify participants. Desk reviews allow M&C to help E-Verify participants correct employment verification activities that M&C has detected as non-compliant. Participants selected for a desk review provide M&C with E-Verify employment-related documents, such as Tentative Nonconfirmation (TNC) notices, referral letters, and employment verification procedures and process documents. M&C reviews and analyzes these documents to determine if the participant is properly following E-Verify policies and procedures. M&C will then assist E-Verify participants to correct any problems and provide an enhanced level of customer assistance.
