USCIS asks you to please download the Historic Records Reports by March 31, 2017, if you have you been using E-Verify more than 10 years
In April 2017, USCIS must dispose of transaction records that are over 10 years old. USCIS has created a Historic Records Report that contains transaction records dated on or before Dec. 31, 2006. E-Verify employers may download these records until March 31, 2017.
E-Verify encourages you to record the E-Verify case verification number on the relating Form I-9, Employment Eligibility Verification, and to retain the Historic Records Report with Form I-9.
