What must occur each time information is requested from an individual under investigation?

The correct answer highlights the requirement that the Privacy Act advisement must be executed each time information is requested from an individual under investigation. This is essential for ensuring that the individual is aware of their rights concerning the request for their personal information. The Privacy Act is designed to protect individuals' privacy by outlining how their data can be collected, used, and shared, and it mandates that individuals receive notice about these practices.

By executing the Privacy Act advisement, the investigator ensures that the individual understands the implications of providing information, including the types of information being requested and the purpose behind the request. This process fosters transparency and accountability, ensuring compliance with legal requirements while safeguarding the individual's rights.

Other options, while important in different contexts, do not consistently apply to each instance of information requests under investigation. For example, a formal interview may or may not be necessary depending on the specifics of the investigation, and a waiver is not a prerequisite for every information request. Thus, the consistent application of the Privacy Act advisement is critical in maintaining compliance and protecting individual rights throughout the investigative process.
