Organizations that have been using E-Verify for more than 10 years or E-Verify Employer Agents whose cases date back to more than 10 years should be aware of the Historic Records Fact Report and Fact Sheet. Of highest importance is information regarding the disposal of historic records. U.S. Citizenship and Immigration Services (USCIS) must annually dispose of transaction records that are more than 10 years old. April is the next time the purge will take place, so it is important for transaction records dated on or before Dec. 31, 2006, be downloaded through March 31, 2017.
