International travel by Members of Congress and their staff is an issue of longstanding interest among some members of the public, media outlets, and Members. Questions regarding the purposes and destinations of international travel by Congress frequently arise, as do questions about the ability to track the costs and benefits of such travel. This report provides information and analysis on the use of foreign currency expended in support of congressional travel to international destinations that is paid for with appropriated funds and authorized by the House or Senate; on measures related to international travel by Congress introduced in the 111th Congress, and administrative actions related to international travel taken by the House; and on potential options for Congress related to international travel by Members and staff. This report does not provide data on travel costs borne by executive agencies that support congressional travel, as those data are not publicly available.
