Can tourists visit the White House or the US Capitol Building?

So it’s been a while sense this was last answered and some things have changed…

White House: Sorry, no more tours! You can thank the sequester for that. You can, however, get in if the President invites you, or you are doing official business. I live 30min away from DC and I have a friend who gets to go to the White House Christmas Dinner every year so it is possible to get in. You can also go when they have events, like Easter Monday on the White house Lawn.

Capitol Building: This one is easy to get in to see. Just go to the East side of the building to the visitors entrance, get in line, and buy a ticket! You’ll get a time to report back for the tour, so I would buy them online so you can pick a good time for yourself. However, a better option is to go see your senator/representative in one of the office buildings next to the capitol. There you can actually meet someone important and you get a private tour of the capitol building by their intern (My high school has a class where you actually get an internship on the hill). You also get tickets to see the senate and the house, which you can only get via talking to your senator/representative. You get to ride the secret subway that takes people back and forth from the offices to the Capitol Building.

Also, while you are in the area, I’d recommend checking out the Library of Congress which is right across the street. You can get to it from the Capital Building via underground tunnel which is really cool (literally).

Also, if you have time, most senate hearings and almost all Supreme Court hearings are open to the public. Take a look on their respective websites to see what they are discussing that day. They can be really fun and who knows, you might even get into one of the medias pictures, securing your spot in history.

For the White House, according to Wikitravel:

President Jefferson opened the White House to the public, and it has
remained so during peacetime (with varying restrictions) ever since.
Following the attacks of September 11th, tours have been available
only for groups of ten or more, and these must be requested up to six
months in advance through your congressman if you’re a US citizen, or
through your country’s embassy in Washington D.C. if you’re a
foreigner.

From the White House website:

Public tours of the White House are available. Requests must be
submitted through one’s Member of Congress. These self-guided tours
are available from 7:30 a.m. to 11:00 a.m. Tuesday through Thursday,
7:30 a.m. to 12:00 p.m. Fridays, and 7:30 a.m. to 1:00 p.m. Saturdays
(excluding federal holidays or unless otherwise noted). Tour hours
will be extended when possible based on the official White House
schedule. Tours are scheduled on a first come, first served basis.
Requests can be submitted up to six months in advance and no less than
21 days in advance. You are encouraged to submit your request as early
as possible as a limited number of spaces are available. All White
House tours are free of charge. (Please note that White House tours
may be subject to last minute cancellation.)

If you wish to visit the White House and are a citizen of a foreign
country, please contact your embassy in Washington, DC for assistance
in submitting a tour request.

The US Capitol building depends on whether you want a self-guided tour, organised, and what you want to see. For information on tours available, and the online booking system, there’s a handy website. Tours are free, but need to be booked in advance (usually) as they can fill up fast, depending on the time of year and occasion.

White House – Tours are available, but you’ll need to do some work in advance, especially if you’re not a US citizen. All tours need to be booked at least 21 days in advance, but especially during busy periods you’ll need to book months in advance to get a spot. They are booked via your Member of Congress for US Citizens, or via your Embassy if you’re not. Details are available at http://www.whitehouse.gov/about/tours-and-events

US Capitol – Tours are available. Tickets are required, but they are free and can be obtained via their website, generally with no more than few days notice being required, except during really busy tourist season in DC (then it’s more like a week). If you’re a US citizen it’s also possible to book via your Representative or Senator. Details are available at http://www.visitthecapitol.gov/ (including the “special activities link on that page”)
