E-Verify is an accurate and robust tool

U.S. Citizenship and Immigration Services (USCIS) have released the results of the most recent Westat Survey conducted on the accuracy of E-Verify, providing further validation that E-Verify is an accurate and robust tool. Though the survey was completed in July 2012, the results are finally being released to the public. Westat conducted the accuracy survey on E-Verify by evaluating the E-Verify Transaction Database.

It’s worth highlighting that employer activity while logged into the E-Verify system is tracked and monitored by USCIS. The survey found that E-Verify accuracy is improving since the last survey released in 2009, which evaluated the tentative nonconfirmation (TNC) rates. The TNC rate in this report declined from 0.7% to 0.3%. Where a secondary review of a TNC is conducted by USCIS, the accuracy rate is 90% effective compared to a 58% effective rate in the absence of secondary reviews.

A substantial portion of the survey was devoted to providing USCIS with recommendations on how to increase E-Verify’s accuracy moving forward, and other recommendations that would streamline the employment eligibility verification process. Some of Westat’s recommendations have already been implemented by USCIS, which potentially explains why this survey wasn’t made publicly available until now.
