A tentative nonconfirmation (TNC) is a preliminary result that arises during the work authorization verification process in the United States, known as E-Verify. It occurs when the information provided by the employee does not immediately match the records in official government databases.

The most important point is that a TNC is not a final denial. It simply signals a discrepancy that needs to be clarified, often due to minor inconsistencies in identity or background data. The individual typically has the opportunity to contest and correct the information.

If a TNC appears, the appropriate course of action is to follow the official instructions and provide the requested clarifications or documents within the indicated timeframes. A few practices help:

  • Keep identity and background documents organized and up to date.
  • Respond promptly to requests for additional information.
  • Review the procedures through the official source or with a specialist.

It is worth noting that the TNC is related to work authorization verification and should not be confused with the merit analysis of the EB-2 NIW itself. Since each situation is individual, confirm the current steps with the official sources (USCIS / E-Verify) before taking action.
