If an employee has worked for a PPO for more than 3 years and is continuing to work for the PPO, can the PPO now shred & throw away that employee's 1-9 form?
Answer: No. The I-9 must be kept the entire time that person is employed, and then for a period afterward. After the employee is no longer employed by that PPO, the PPO must keep the I-9 for whichever of these is LONGER: 3 years from the date that person was hired, or 1 year after his/her employment ended.
