The Humphrey Program is funded primarily by a Congessional appropriation to the United States Department of State. The Bureau of Educational and Cultural Affairs of the Department of State and the Institute of International Education (IIE) administer the program jointly through a cooperative agreement.  IIE contributes donated staff time, recruitment of pro bono experts and speakers, shared event costs, and other administrative resources to the Humphrey program.  Participating governments and host institutions contribute financial support through direct cost-sharing.

 The Program also benefits from the generous support of several co-funders:

• National Institute on Drug Abuse (NIDA) – The National Institute on Drug Abuse (NIDA), which supports more than 85% of global research on drug abuse and addiction, sponsors several Humphrey Fellows. In order to be considered for funding by NIDA, candidates must hold an advanced graduate degree in medicine, health, biomedical, behavioral, or the social sciences and have significant research experience.
  
• The Republic of Korea/Ministry of Government Administration and Home Affairs (MOGAHA) – Due largely to an initiative of the Humphrey Alumni Association of Korea, the Korean Ministry of Government Administration has funded Humphrey Fellows from South Korea every year since 1997.


• The International Monetary Fund and the World Bank – An annual Enhancement Workshop for Fellows on international finance is co-hosted by the International Monetary Fund and the World Bank in Washington, D.C.


• Emory University, Rollins School of Public Health – Emory University has donated support for an Enhancement Workshop on Global Development and Social Justice at the School of Public Health for more than a decade.


• American Management Association – As part of a partnership with the Institute of International Education, the American Management Association offers space-available access to its seminars at no cost to IIE program participants, including Humphrey Fellows. 


• Employers – In addition to granting leave status to Humphrey Fellows, many employers continue to pay Fellows their annual salaries.  This generous assistance enables Fellows to support their families and participate in the Humphrey Fellowship Program.


• Host Campuses –  Each Humphrey host university provides in-kind support to the program, including tuition reduction, donated office space, computers, and staff time.
