How long is a governmental letter of authority valid?

A governmental letter of authority is valid for one year. This one-year validity period is designed to ensure that the authorization remains current and relevant, as it allows for periodic review and reassessment of the requirements and criteria under which that authority was granted. By establishing a one-year time frame, the issuing authority can evaluate changes in regulations, needs for security services, or any other relevant factors that may necessitate a renewal or modification of the letter of authority.

The one-year duration reflects a balance between providing adequate time for security operations to be conducted under the authority granted and the need for regular updates to ensure compliance with current laws and practices.
