These Congressional tours usually occur early in the morning before the buildings open up to the general public. Tickets for tours are very limited, and I encourage Texans to contact my Washington, D.C. office as soon as they know they will be visiting the capital. For example, each Congressional office is allotted only 5-15 White House tickets per week, which are invariably reserved months in advance by visitors. Requests are much higher in the spring and summer months. Below are sites that offer ticketed tours, and the recommended time to request tickets.
Public tours are available as well.
Demand for tours is highest in the spring and summer months. Gallery passes are available upon request for every Texan interested in visiting the House or Senate Visitors' Galleries. Please note that these services are intended for Texas residents, including U.S. Military personnel who list their residency in Texas.
