While employers may use the Form I-9 with the revision date of either Aug. 7, 2009 or Feb. 2, 2009, EVRI recommends to only use the latest (Rev. 08/07/2009) version as there are invalid forms with the 06/30/2009 expiration date (but not the Rev. 02/02/2009). The revision dates are located on the bottom right-hand portion of the form, the expiration dates are located on the top right-hand portion of the form.
 
Also, employers should be aware that using an expired form for rehire purposes is not acceptable. Any rehire that had earlier completed a now invalid form I-9 should just complete an entirely new form, regardless of company policy.
 
Please contact us should you be having difficulty in completing the form or wish to discuss a particular document's validity for I-9 purposes, we will be happy to assist!
