How often do you have to update I9 forms?

Form I-9 is Employment Eligibility Verification. It's a form that's issued by U.S. Citizenship and Immigration Services. Section 1 (Employee Information and Verification) must be completed by the employee no later than the time of hire. If the employee indicates an employment authorization expiration date, the employer is required to reverify employment authorization on or before the expiration date. The employer has two options in updating and reverifying. One, he can complete Section 3 (Updating and Reverification) of the current I-9 form. Two, he can have the employee fill out a new I-9 form.
