NIH Support of International Research: Navigating NIH Public Resources

NIH remains committed to funding strong international collaborations when conducted in a secure, justifiable, and responsible way that ensures benefits for the American people.

The new application and award structure for NIH applications that request funding for international component organizations was published: PA-26-002 NIH Collaborative International Research Project (Parent PF5 Clinical Trial Optional). The PF5 application needs to be submitted by a U.S. institution and include at least one proposed funded international subproject (replaces foreign subawards). The PF5 uses a multi-project application. Additional resources are expected soon.

NIH funds international research with scientific and technical justification via:

• Direct foreign awards or direct foreign awards with U.S. subawards. Check the funding opportunity for eligibility.
• U.S. prime awards with foreign subprojects (PF5/RF2 or UF5/UL2). If chosen for funding, foreign subprojects will be converted into independent foreign awards.

Funding opportunities allowing foreign components may continue to accept applications with unfunded international collaborations (e.g., U.S.-Ireland R&D Partnership Program) or foreign components other than those previously supported by subawards or consortia agreements (e.g., foreign consultants, international travel) may continue to be supported through other activity codes unless otherwise indicated in the NOFO.
