How long must a PPO retain the I-9 form for current employees?

The correct answer indicates that a Private Patrol Operator (PPO) must retain the I-9 form for as long as the employee is employed. This is in line with federal regulations which require employers to keep I-9 forms for each employee as evidence of their eligibility to work in the United States.

The rationale behind retaining the I-9 for the duration of employment is to ensure compliance with immigration laws and to provide proof that the employee has been verified for work authorization while they are actively employed. Once the employment relationship ends, there are specific guidelines about how long to keep the I-9 form, which is why it is important to understand that the retention period directly correlates with the employee’s status in the company.

The other options reference specific durations that apply after termination or hiring, but those do not pertain to the ongoing employment period. It's crucial for employers, including PPOs, to be aware of their obligations regarding employment verification documentation throughout the time an employee is part of their workforce.
