    Every person — employee, contractor, or long-term visitor — who has

    Assessment on file. PSAs are valid for up to five years and include
    a review of citizenship, criminal record, and loyalty considerations.

    PSA records are restricted via ``ir.rule`` so that only the CGP
    Officer and Designated Official can see them. A regular plating
