I-9 information

On your first day of employment at Fermilab, we must complete an I-9 Form for you. We also will submit the information from the I-9 to E-Verify electronically. When you arrive at Fermilab for your new hire orientation, you MUST BRING original documentation acceptable for I-9 and E-Verify purposes. The table below outlines what is acceptable documentation. Photocopies are not sufficient.

Background | Document Lists | I-9 and E-Verify procedure during new hire orientation


It is a requirement of U.S. law that all employers verify the identity and work authorization of every employee in the United States, regardless of citizenship. The Immigration Reform and Control Act of 1986 (IRCA) created this obligation. The I-9 Employment Eligibility Verification Form is the government form used for this. More information about I-9s can be found on the U.S. Citizenship and Immigration website at www.uscis.gov at I-9 Central or I-9 Central Home.

E-Verify is an internet-based system operated by the Department of Homeland Security (DHS) in partnership with the Social Security Administration (SSA). E-Verify compares information from an employee’s I-9 Form to the data in U.S. government records. As a federal contractor, Fermi Research Alliance, LLC (which operates Fermilab) is required to participate in E-Verify. More information about E-Verify can be found on the USCIS website at www.uscis.gov or E-Verify.

I-9 and E-Verify procedure during new-hire orientation

Every employee hired after November 6, 1986, must complete Section 1 of the I-9 form on or before the date of hire (the first day for which the employee will be paid).

  • Most employees will be emailed a login and password for Fermilab’s electronic I-9 system, called Guardian, which is at www.perfectcompliance.com. If you do not receive a login and password within 1 week of your new-hire orientation, please email your recruiter.
  • Note: non-U.S. citizens hired from abroad do not receive Guardian passwords and logins.

The new employee must present certain original documentation within three days of starting work (if your first day of work is Monday, then you must present these original documents by the close of business on Wednesday). Photocopies or other facsimiles of these documents are not acceptable. The employer then completes Section 2 of the I-9 Form using those original documents.

  • In general, Fermilab requires I-9s to be completed on the day of hire.
  • Failure to provide the necessary documentation by the end of your third day of employment will require us to place you in a leave of absence without pay until appropriate documentation is produced to complete the I-9 Form.

If the information matches, E-Verify confirms that the individual is eligible to be employed. Mismatches of data result in tentative nonconfirmation, which the employer and employee must resolve. Usually, this involves the employee correcting the government data (such as correcting a name change or typographical error in government records). The employee may remain employed during resolution of a tentative nonconfirmation and, in accordance with U.S. law, will be paid for time spent in coordinating the resolution (such as traveling to Social Security Administration or USCIS offices to correct government errors).
