(CT:LOG-)
(Office of Origin:  A/LM)

14 FAM 521  GUIDELINES FOR ISSUING TRAVEL AUTHORIZATIONS

14 FAM 521.1  Purpose of Official Travel

(CT:LOG-253;   10-01-2018)
(Uniform State/USAGM/USAID/Commerce/Agriculture)
(Foreign Service)

Authorizing officials should be cognizant of any personal or other travel plans, including plans to take annual leave in conjunction with travel, and should consider the need for the travel, use of travel substitutes (mail, teleconferencing, etc.), and the most cost-effective routing and means of accomplishing travel.  Personal leave during official travel must not increase the cost of the travel to the U.S. Government.  Each travel authorization and the associated travel vouchers must clearly specify the purpose of the travel.

14 FAM 521.2  Types of Travel Authorizations

(CT:LOG-253;   10-01-2018)
(Uniform State/USAGM/USAID/Commerce/Agriculture)
(Foreign Service)

The use of general travel authorizations for entire agencies or groups of employees must be authorized only by the Executive Secretariat and the Bureau of Administration in specific circumstances.  To assure adequate managerial and supervisory attention to the need for all travel, each employee's travel must be authorized separately under one of the types of travel authorizations detailed below.

14 FAM 521.2-1  Unlimited Open Authorization

(CT:LOG-253;   10-01-2018)
(Uniform State/USAGM/USAID/Commerce/Agriculture)
(Foreign Service)

An unlimited open authorization permits an individual to travel for any purpose without further authorization.  The Secretary of State has an unlimited open authorization.

14 FAM 521.2-2  Limited Open Authorization

(CT:LOG-253;   10-01-2018)
(Uniform State/USAGM/USAID/Commerce/Agriculture)
(Foreign Service)

A limited open authorization permits an individual to travel without further authorization under certain prescribed conditions, which may include limitations on the purpose(s) of travel, the geographic areas that may be visited, trip costs, and the period of time in which travel is authorized.

14 FAM 521.2-3  Trip-by-Trip Authorization

(CT:LOG-253;   10-01-2018)
(Uniform State/USAGM/USAID/Commerce/Agriculture)
(Foreign Service)

A trip-by-trip authorization permits a group or an individual to take one or more specific trips identified as to purpose(s), itinerary, time period, and estimated cost.

14 FAM 521.3  Open Authorizations

(CT:LOG-253;   10-01-2018)
(Uniform State/USAGM/USAID/Commerce/Agriculture)
(Foreign Service)

To minimize administrative costs and to provide for necessary flexibility while maintaining essential controls, use of open authorizations must be as follows:

(1)  Unlimited open authorizations for travel must be permitted only for Department or agency heads, their deputies, other principal assistants, and managers as designated by the agency head or deputy;

(2)  Limited open authorizations may be provided for employees whose work requires frequent repetitive travel, but should be revalidated quarterly and should specify realistic limitations on purposes, geographic area, trip duration, and costs; travel not covered in an open authorization must be separately authorized on a trip-by-trip basis; and

(3)  Unlimited (except in the case of the Secretary and agency heads) and limited open authorizations must include an estimate of the travel costs to be incurred over the period covered by the authorization.  Those estimates will be used to obligate those funds necessary to carry out that travel and thereby provide travel budgetary controls.

14 FAM 521.4  High-Cost Travel Authorizations

(CT:LOG-253;   10-01-2018)
(Uniform State/USAGM/USAID/Commerce/Agriculture)
(Foreign Service)

Because of the relatively high costs associated with certain kinds of travel, such travel must be authorized on a trip-by-trip basis and reviewed at a level of authority sufficient to provide policy approval.  The types of travel covered by this requirement are:

(1)  All conference attendance, training, entitlement, and relocation travel.  In the case of conference attendances, as defined in the travel purpose categories (see 14 FAM 533.4), the authorizing official must assure that the numbers of attendees from the Department are necessary and justified.  In addition, the need for conferences and meetings for which total travel and per diem estimates exceed $5,000, must be authorized by, at a minimum, an Assistant Secretary, executive director, the Deputy Administrator for the U.S. Agency for International Development (USAID), or equivalent;

(2)  Travel outside Continental United States (CONUS) for all employees, except those whose work requires repetitive foreign travel or emergency foreign travel without advance notification.  In addition, U.S. Government representatives and attendees at international, multilateral, and intergovernmental conferences must be accredited by the Bureau of International Organization’s Office of International Conferences (IO/C), the Executive Secretariat (S/ES), or the Bureau of Administration’s Presidential Travel Support Division (A/PTS); and

(3)  Authorization of other travel should be delegated to the lowest management level that has responsibility for both program accomplishment and/or obligation or commitment of funds, but not lower than an office director, bureau travel manager, or equivalent.  The requesting and authorizing official should not be the same person, unless a higher authority is not available.  In the latter instance, a specific memorandum of approval to authorize travel must be issued by the next higher organizational level.
