The U.S. Citizenship and Immigration Services is tinkering with the I-9 Form again. Effective February 2, 2009, employers may no longer accept expired documents to verify a worker’s employment eligibility. The agency stated its concern with counterfeiting as a justification for this new prohibition.

Additionally, the form itself has changed. Previously, employees attested that they were either (1) a “citizen or national of the United States,” (2) a lawful permanent resident or (3) an alien authorized to work until a specified date. The new form gives employees four choices by splitting option (1) into two options: citizen or national. Lastly, the form contains instructions regarding reverification and permits certain people, mostly asylees or refugees, to leave the expiration date blank.
