To facilitate the Imperium, a governing structure has been developed which follows the Star Trek "Romulans" as closely as possible. This structure helps administer chapters and members in all of the branches of service.

 Some positions within RSE International are governing positions, meaning they help run and operate the actual organization. Other positions are strictly roleplaying positions, facilitating the fictitious world of the Romulan Star Empire. Some governing duties mix with roleplaying. When communicating with any of these positions, it should be clear what is real and what is not.

RSE International is a not-for-profit organization that has a legal governing body. The president (Praetor) leads the organization with the assistance and advice of the vice-president (Subpraetor). An executive committee (Continuing Committee) completes the governing board.

The Imperial Praetor (IP) serves as RSE International's president. The IP is responsible for the overall administration of the Imperium and its funds, as well as its records.  The IP holds the final decision on all matters concerning the Imperium.

The Imperial Subpraetor (ISP) serves as RSE International's vice-president and acts as the Praetor's Chief of Staff.

The Civilian Coordinators reflect the views of the membership, not necessarily that of the command heads, and thus, represent all members. In addition, all business may be conducted by mail or e-mail due to geographical separation of RSE International's governing body.

Many members are involved in RSE International primarily at the chapter level, and often interact with other chapter members, as well as their department or division Command heads and staffs. Communication between divisions and individual members is highly encouraged and advised.

In RSE International there are several membership departments, such as, but not limited to:  Star Navy (Galae), Tal Shiar, Diplomatic Corps, Tal Prai'ex, and so forth. While each of these departments have a "real-life" function within the Empire, these are the branches which members will either be attached to or will interact with the most.  Other departments, such as Quartermaster and the Academy, are support departments which provide essential resources, and ensure the enjoyability and quality of the RSE International experience.

RSE International is the world's oldest and largest Star Trek fan organization dedicated to the Romulans.
