Tickets for the White House, U.S. Capitol, FBI Headquarters, and Bureau of Engraving and Printing are free of charge. If my office is unable to secure a congressional tour for the sites you selected, most other sites are available for public tours. Please visit the House visitors guide
https://www.house.gov/visitors for information about public tour information for many of the sites in Washington D.C. Admittance is determined by the individual tour site or agency, not by the Congressional office.
White House tours are available on Tuesdays through Saturdays, and the White House Visitor’s Office decides the start time between 9:30 am through 12:30 pm for accepted tours. Congressional tour coordinators can request up to three dates to provide a better chance of acceptance. Tours are around 45 minutes and self-guided. The White House Visitor’s Office contacts those who requested tours 14 to 21 days before the requested date to inform of acceptance or denial, and they provide the date and time of the tour if accepted.
U.S. Capitol tours are available on Mondays through Saturdays, with ticket start times ranging from 8:50 am through 3:20 pm on a first come, first served basis. Group sizes are based on availability.
FBI tours are available on Mondays through Fridays with timed-entry tickets available at 9:00 am, 10:00 am, 1:00 pm, and 2:00 pm on a first come, first served basis. Groups are limited to 10 people based on competitive availability.
Bureau of Engraving and Printing tours are available Mondays through Fridays. Tours scheduled through a Congressional office are available year-round at 8:15 am or 8:45 am and additionally 4:00 pm, 4:15 pm, 4:30 pm, and 4:45 pm between late March and Labor Day only. Otherwise, public tour tickets will be distributed daily beginning at 8:00 am on a first-come first-serve basis at the BEPs Tour entrance, located on 14 and C Streets, SW. Public tours tickets are available for 10 am, 11 am, 1 pm, and 2 pm. Groups are limited to 10 people based on competitive availability.
