Tours of the White House are given only by advance notice and set up through the member of Congress associated with the state the person requesting the tour is a citizen of. Tours are only given for groups of 10 or more people for safety reasons, and smaller groups and families should request to join a tour rather than create a time for a new tour.
If a tour is requested, the submission of a request through the office of congress should be turned in up to 6 months in advance as background checks are required for people wishing to tour, with no less than 21 days in advance given before the request. Visitors who are not U.S. citizens should contact their embassy in Washington, D.C., to request a tour, and will be given instructions from that point.
Tours of the White House are self-guided as to not disturb general business. An official, government-issued photo ID must be presented before entrance is allowed, and an official passport will need to be shown for non-U.S. citizens. Tours are admission free for all. A visitor's center provides the option for virtual and interactive tours, along with many historical artifacts up for viewing that cannot be seen anywhere else.
