US Citizenship and Immigration Services (USCIS), on the page titled "What Is E-Verify?" on the USCIS website, updated July 20, 2017, stated:

“E-Verify is an Internet-based system that compares information from an employee’s Form I-9, Employment Eligibility Verification, to data from U.S. Department of Homeland Security and Social Security Administration records to confirm employment eligibility…

E-Verify’s most impressive features are its speed and accuracy. E-Verify is the only free, fast, online service of its kind that verifies employees’ data against millions of government records and provides results within as little as three to five seconds.

Today, E-Verify is:

  • Used nationwide by more than 500,000 employers of all sizes
  • Used at more than 1.4 million hiring sites
  • Joined by about 1,400 new participating companies every week
  • One of the federal government’s highest-rated services for customer satisfaction.”
[Editor’s Note: On Aug. 15, 2011, in order to better understand the E-Verify program while developing this pro-con question, enrolled in the E-Verify program at the US Citizenship and Immigration Services (USCIS) E-Verify homepage: The process took approximately 50 minutes from start to finish and required us to input data about the company and its proposed use of E-Verify (10 minutes); electronically sign a memorandum of understanding (MOU) and wait for an approval confirmation email and temporary password (five minutes); log in with the temporary password, change the password, and complete an E-Verify tutorial (30 minutes); and pass a multiple-choice knowledge test with a score of 70% or higher (five minutes).] July 20, 2017
