Which statement describes the duration of an interim letter?

• A. 60 Days or less
• B. 90 Days
• C. 30 Days
• D. 120 Days

Answer: (A)

Interim letters are temporary authorizations kept short to bridge a pending action without granting long-term authority. The standard upper limit is sixty days or less, which provides enough time to complete required processing (like background checks or documentation) while preventing the interim status from becoming effectively permanent. Choosing durations like ninety, thirty, or one hundred twenty days would either extend beyond what is typical for an interim arrangement or be too short to realistically complete the necessary steps, so sixty days or fewer best matches the intended use.
