Staffing agencies should not leave the Certification Date or Hire Date field blank. When completing Section 2 of Form I-9, staffing agencies may choose to use either the date a new employee is assigned to his or her first job or the date a new employee accepts an offer and is entered into the assignment pool as the first day of employment. USCIS recommends that staffing agencies remain consistent with regard to the date it chooses to use as the first day of employment when completing Forms I-9 and E-Verify cases.
