The stated duties of the secretary of state are to supervise the United States foreign service and immigration policy and administer the Department of State. The secretary must also advise the president on U.S. foreign matters such as the appointment of diplomats and ambassadors, advising the president of the dismissal and recall of these people. The secretary of state can conduct negotiations, interpret, and terminate treaties relating to foreign policy. The secretary also can participate in international conferences, organizations, and agencies as a representative of the United States. The secretary communicates issues relating to the U.S. foreign policy to Congress and citizens. The secretary also provides services to U.S. citizens living or traveling abroad such as providing credentials in the form of passports. Doing this, the secretary also ensures the protection of citizens, their property, and interests in foreign countries.[13]
What are the Qualifications of a Secretary of State? He ought to be a Man of universal Reading in Laws, Governments, History. Our whole terrestrial Universe ought to be summarily comprehended in his Mind.
โJohn Adams[14]
Secretaries of state also have domestic responsibilities, entrusted in 1789, when the position was first created. These include the protection and custody of the Great Seal of the United States, and the preparation of some presidential proclamations. In the process of extraditing fugitives to or from the country, the secretary serves as the channel of communication between foreign governments, the federal government, and the states.[13]
Most of the domestic functions of the Department of State were gradually transferred to other agencies by the late 19th century as part of various administrative reforms and restructurings.[15] Those that remain include storage and use of the Great Seal, performance of protocol functions for the White House, and the drafting of certain proclamations. The secretary also negotiates with the individual states over the extradition of fugitives to foreign countries.[16] Under federal law, the resignation of a president or of a vice president is valid only if declared in writing, in an instrument delivered to the office of the secretary of state.[17] Accordingly, the resignations of President Richard Nixon and of Vice President Spiro Agnew were formalized in instruments delivered to then-Secretary of State Henry Kissinger.
