Collect the employee's Form I-9 Section 1 data and supporting document information required for E-Verify case creation before proceeding.
Create the E-Verify case no later than three business days after the employee's first day of employment, using either the web interface or Web Services integration.
Review the initial case result; if Employment Authorized is returned, record the case number and close the case.
If a Tentative Nonconfirmation (TNC) is returned, notify the employee as soon as possible and no later than within the 10 federal government working days allowed for employer action; provide the employee a copy of the Further Action Notice.
If the employee chooses to contest the TNC, refer the case in E-Verify and inform the employee they have 8 federal working days to contact DHS or SSA to resolve the mismatch; the employee must be allowed to continue working during this period.
Monitor the case for resolution and update your records with the final case result when it becomes available.
Known gotchas
Creating a case more than three business days after the first day of employment is a program violation; late case creation must be documented with a reason and does not retroactively cure the timing issue.
An employer may not take adverse action against an employee solely because of a TNC result while the case is still open — doing so constitutes an unlawful employment practice under E-Verify program rules.
Employees have the right to contest or not contest a TNC; if the employee chooses not to contest, the employer may terminate but must follow applicable employment laws and document the decision.
