What must the application for a security officer certification be submitted to?

The application for a security officer certification must be submitted to the Mayor because the Mayor's office oversees the licensing and regulation of security personnel within the District of Columbia. This process ensures that all security officers meet the necessary standards and comply with local laws and regulations. The Mayor’s office is responsible for implementing policies regarding public safety and security, which includes the certification of security officers.

Other entities mentioned, such as the local police chief or the Department of Homeland Security, do not have jurisdiction over the certification process for private security personnel in the district. Similarly, while a security agency supervisor plays a role in the employment and operational aspects of security officers, the official process of certification submission is designated to the Mayor’s office.
