Employers often use E-Verify and Form I-9 interchangeably.
But the truth is, while they are related, they are very different processes.
Form I-9, from the U.S. Citizenship and Immigration Service
(USCIS), is the core of E-Verify.  It is
used by an employer to verify an employee’s identity and eligibility for employment
in the United States. E-Verify is not to be mistaken as an electronic version
of Form I-9.  E-Verify is an
internet-based system that compares information from the Form I-9 to government
records to confirm that an employee is authorized to work in the United States.
Although E-Verify uses information from Form I-9, there are
some important differences between Form I-9 and E-Verify requirements:
 
  | 
                        Form
  I-9 | 
E-Verify | 
  | 
Is mandatory | 
Is voluntary for
  most businesses | 
  | 
Does not require a Social Security number | 
Requires a Social Security number | 
  | 
Does not require a photo on identity documents
  (List B) | 
Requires a photo on
  identity documents (List B) | 
  | 
Must be used to re-verify expired employment authorization | 
MAY NOT be used to re-verify expired
  employment authorization | 
Therefore, E-Verify cannot be used to replace Form I-9.
E-Verify is used in conjunction with Form I-9 to help employers confirm that an
employee is authorized to work in the U.S. 
Why would an employer
utilize E-Verify?
1.     It may be a requirement if the employer is a federal contractor or
conducts business in a state that requires it.
2.     Participation makes it possible to hire some foreign students doing
extended Optional Practical Training in a STEM (Science, Technology,
Engineering, or Math) profession.
3.     E-Verify creates a presumption of an employer’s good faith compliance in
the event of an I-9 audit.
4.     Many employers, especially those with large payrolls and multiple offices
throughout the country, like the ease of using E-Verify and the security it
provides in ensuring a legal workforce, especially when used in conjunction
with an electronic I-9 system.
