For closed cases, do not create a new case for the employee under the correct employer account. You should attach a note to the employee’s Form I-9 explaining the situation and sign and date the note, then notify E-Verify of the situation by contacting E-Verify Contact Center.
If the case resulted in a Tentative Nonconfirmation (mismatch) case result, select the statement indicating the employee will not take action and you will have the option to close the case. After closing the case, create a new case for the employee under the correct account.
