The Office of Language Services carries on a tradition of language support for the conduct of foreign policy that dates back to 1789, when it was founded by Thomas Jefferson, the first Secretary of State of the United States of America.

The office consists of an Interpreting Division and a Translation Division. An Assigning Unit is responsible for providing interpreters for exchange programs run by the Department. Administratively, Language Services is an office within the Department of State, but has delegated authority to provide interpretation and translation services to the White House as the sole provider. Many other agencies of the U.S. Federal Government also rely upon Language Services for diplomatic/conference interpretation services, by special arrangement, where the services requested have a direct and substantial relationship to the conduct of foreign affairs. As the only federal entity with a Division specialising in diplomatic/conference interpretation, the Office of Language Services is uniquely positioned to fulfill this mandate.

Interpretation Service

The Interpreting Division staffs roughly 7,000 interpreting days in over 40 languages on a routine basis annually, and the volume of work handled by the office is expected to continue to grow exponentially in the coming years.

The Department of State has eight venues equipped with built-in simultaneous interpretation booths, ranging from two large auditoriums with 15 and 11 booths respectively, to smaller meetings rooms with three or four booths each. Mobile booths are used frequently in other meeting rooms at the Department and in the Washington DC area. The Office of Language Services has a dedicated classroom with eight booths that is used solely for training and testing purposes.


The Office of Language Services employs roughly 60 diplomatic/conference interpreters, translators, and administrative officers on staff. The Interpreting Division has approximately 20 senior conference interpreters, diplomatic interpreters, and senior diplomatic interpreters representing a dozen languages in permanent positions. Staff must hold U.S. citizenship and be able to interpret bi-directionally in their primary language combination. Some, but not all, staff interpreters also translate, and some staff translators also work as interpreters.

The Office of Language Services also has standing contractual relationships with over 1,600 interpreters and translators who work for us in a freelance capacity on an intermittent basis. Roughly 750 of these contractors are interpreters representing a total of more than eighty languages.  Both full time staff and contract linguists must undergo routine screening for a security clearance or public trust designation.


Interpreted events range from bilateral and multilateral meetings and negotiations to appointments of traveling delegations and large international conferences. Staff interpreters and senior contractor interpreters travel with the President, First Lady, Secretary of State, and other Cabinet members, and routinely interpret meetings and phone calls held at the White House and Department of State. Staff and contractors also interpret at working-level meetings in the Washington area and throughout the United States on topics representing the full spectrum of business conducted by the United States government, ranging from agriculture, to arms control and security, commerce and business, defense, democracy and human rights, energy and the environment, finance, health, humanitarian assistance, narcotics and law enforcement, nonproliferation, public diplomacy, science and technology, and transportation, among others. In contrast to many other areas of conference interpreting, the consecutive mode is used frequently in meetings and conferences at all levels. Assignments can be remarkably varied, consisting for example of a phone call with very little lead time between a member of the U.S. government and a foreign counterpart on one day and an international summit that requires fifteen or more booths and months of planning the next.

In addition to interpreting at the master level, all staff interpreters serve as chefs d’équipe at multilateral meetings and as linguistic and cultural consultants to U.S. delegations and representatives. Senior staff interpreters also recruit, screen, test, and/or train interpreters for staff and contract work and serve as consultant interpreters to offices, agencies, and other federal government institutions that request interpretation services. The work of both staff and contractors requires a thorough grasp of the issues, policies, and positions under discussion and consistent personal initiative in adapting research and planning under rapidly changing circumstances and work environments.

The Office of Language Services requires a range of skill levels among contract linguists.  Seasoned freelancers in language combinations not represented on staff may work for the most senior levels of the United States government, while talented colleagues just beginning their careers may be offered public diplomacy and working-level assignments on a regular basis if their language combination is in demand.

Recruitment Conditions and Benefits

Staff positions are filled through an open and competitive process. Job announcements are posted at the U.S. federal government’s portal for jobs and employment information,, and eligible candidates are interviewed and tested bi-directionally in diplomatic consecutive and simultaneous interpretation. Staff diplomatic interpreters must be U.S. citizens and able to acquire and maintain a Top Secret security clearance. They are hired as career-track civil servants, whose positions become permanent after a probationary period and remain in place from one administration to the next. Staff interpreters are remunerated at the 13, 14, or 15 levels of the General Schedule (GS) and receive a comprehensive benefits package. Information on compensation and benefits can be found at

Contract interpreters may be foreign nationals, but they must be able to work legally in the United States and have a U.S. bank account. Applicants are normally screened first for basic consecutive interpreting ability over the telephone and then may be formally tested for consecutive, simultaneous and/or conference work at three different levels of skill. All tests are conducted in the testing and training facility located in Washington DC. The best method of preparing for contractor tests is to review videos and transcripts posted at the White House and State Department websites (, and general information about the United States posted at The Office of Language Services contracts only with individuals, not corporate agencies or entities. 

Interpreters interested in contract work should complete an application form and submit it with a current resume following the instructions at the website: Additional information on contract work for the Office of Language Services, to include information for translators, is available at the website.

Living in Washington, D.C.

The United States Congress established the District of Columbia in 1792 on land ceded by the states of Maryland and Virginia. Located at the confluence of the Anacostia and Potomac rivers, Washington is both the national capital and an international center. Planned for a specific purpose, this ‘city of heroes and monuments’ was designed by Major Pierre-Charles L’Enfant, a French-American architect and volunteer during the War of Independence. L’Enfant’s simple plan for a concentric city pierced by wide avenues imparted to the city an ordered charm that is at once graceful and austere.

In 1800, the city became the seat of the federal government. An attractive dynamic city, Washington serves as the federal capital for the fifty states that comprise the United States. It is the home of the nation’s three branches of government: the Executive Branch directed by the President, the Legislative Branch consisting of the U.S. Congress, and the Judicial Branch headed by the Supreme Court. Numerous government agencies, departments, commissions, and services are headquartered in the District of Columbia. The operation of the government attracts a variety of organisations, institutions, businesses, and public interest groups that closely follow the daily operations of all three branches of government.

Due to the importance of the United States in world affairs, Washington has become a center for diplomacy and international activities. The presence of diplomatic representatives from all over the world and agencies concerned with international economic development and global issues helps make Washington a cosmopolitan place to live, work, and visit. Indeed more than 150 embassies are located in the city, and more than 20,000 diplomats call Washington home.

The nearly 600,000 District of Columbia residents also elect one non-voting member to the House of Representatives of the U.S. Congress. About four million people live in the greater metropolitan area. In the center of this city of monuments and museums is the popular National Mall, a splendid green park area extending approximately two miles from the U.S. Capitol to the Lincoln Memorial. Lining either side of the park are many museums of the Smithsonian Institution, the largest museum complex in the world, as well as the National Gallery of Art, the National Archives, the U.S. Botanic Gardens, the Museum of the American Indian, and the World War II Memorial. The Washington Monument, Jefferson Memorial, Lincoln Memorial, and the Vietnam Veterans Memorial are also popular sites to visit on the Mall.

The historic Georgetown district of Washington contains many specialty shops, nightclubs, and restaurants, while the Adams Morgan area is hailed as the city’s most ethnically diverse neighborhood. The H Street Corridor, Logan Circle/U Street, and the area around the Verizon Center are fast becoming popular destinations for gastronomic and cultural activities. Popular destinations for day trips and overnight excursions include Old Town Alexandria, Mount Vernon, Monticello, Shenandoah National Park, Gettysburg, Annapolis, Baltimore, Philadelphia, the eastern and western shores of Chesapeake Bay, and beaches along the Atlantic coast.
