Directorate for Social, Behavioral, and Economic Sciences
Office of International Science and Engineering

Science and engineering are, and always will be, international enterprises critical to U.S. competitiveness and security. The National Science Foundation (NSF) plays a unique role in leading the worldwide efforts of the American science, engineering, and education communities. The Office of International Science and Engineering (INT) serves as the focal point for the agency’s international science and engineering activities. The office works in close partnership with NSF Directorates on international research collaborations and training opportunities. It also manages its own programs that include support for U.S. scientists, engineers, and students (undergraduates, graduate students, and postdoctoral researchers) involved in international projects.

Submission of Proposals to the Office of International Science and Engineering (INT)

Depending on the nature of a proposed project, a grant proposal may be submitted to INT directly or to the appropriate disciplinary division. International supplements to existing grants from the Foundation’s research and education directorates also may be requested. Principal investigators who are considering applying for an INT supplement should discuss the scope and timeframe of their proposed activity with both the cognizant program manager in the disciplinary research division and the appropriate (normally, geographically based) program manager in INT.

INT typically supports the international costs of the U.S. participants in an activity. Further detailed information such as special considerations and funding provisions for certain geographical regions or countries can be found on the INT home page,, where instructions and guidelines for each program initiative are provided.

Information is also available in the following program announcements: International Opportunities for Scientists and Engineers (NSF 03-559), International Research Fellowship Program (NSF 02-149), East Asia Summer Institutes for U.S. Graduate Students (NSF 02-174), and Pan-American Advanced Studies Institutes Program (NSF 03-506).

INT participates in a number of NSF crosscutting programs, encouraging international cooperative activities, especially in the Program for Integrative Graduate Education and Research Traineeship (IGERT) and the Program for Research Experiences for Undergraduates (REU). Further information about these programs can be found on the NSF Crosscutting Programs Web site,

Eligibility Requirements for the Office of International Science and Engineering

Eligible for consideration are proposals submitted by U.S. scientists and engineers for international activities in all fields of science and engineering normally supported by NSF. A U.S. institution should submit the proposal. Two exceptions to this procedure are the International Research Fellow Awards and the East Asia Summer Institutes for U.S. Graduate Students Program, which accept applications directly from individuals who are U.S. citizens or permanent residents. Proposals submitted to INT normally compete in one of five regional groupings. Proposals for International Research Fellow Awards are in a separate competition.
