Disclaimer
do not waste time getting I-9 information on all applicants – this is only required for people who are actually hired
the law requires employers to verify the I-9 information by the end of the third day of an employee's employment
employers are not required to keep copies of the documents a new hire presents for the I-9 form, but keeping copies will help a company show that it tried in good faith to verify the identity and work authorization of the employee
I-9 records must be kept for three years following the date of hire, or for one year after the employee leaves, whichever is later – recommended: keep this and all employment records for at least 7 years after the employee leaves in order to exhaust all the statutes of limitation
