However, during holiday periods or the peak visitor season between President's Day and Labor Day, the wait can be upwards of two hours. Larger groups, particularly school groups who wish to visit the FBI during the spring, should write to the FBI directly at the above address up to one year in advance of their visit. The letter should be written on the school or organization's letterhead stationary. It should contain the name and address of the group, a telephone number, a designated contact person, the desired visitation date, and the total number of persons in the group, including chaperons. Reservations may not be made either through the Internet or by tour companies on behalf of their clients.

All visitors must pass through a security check and, in the case of scheduled appointments, name checks will be done. Walk up the ramp to enter the building.
