If desired, visitors may obtain advance tickets to five major attractions from their congressional representative's office. However, obtaining advance tickets is not required for touring any of these attractions. There is no guarantee that visitors will receive Congressional Guided Tour tickets when they request them.

In all cases, visitors are advised to contact their representative's office several months in advance of their trip to Washington.
