For more than two decades, employers within the United States have been required to verify the work authorization of new hires (8 USC 1324A et seq.). This verification is performed by reviewing documentation tendered by the new employee to confirm identity and immigration work authorization and memorializing the results in a form I-9. The form is retained by the employer for three years after the date of hire of the employee or one year after the date that employment is terminated, whichever is later. The form is not filed with the government.
