We do not have specific guidance from all sponsors on this topic, however, per NIH guidelines, this person’s work on the project should be documented as follows:

• As “Other Support” because the externally funded individual is a “resource available in direct support of [your] research endeavors.” The NIH recently clarified that “all research resources including, but not limited to, foreign financial support, research or laboratory personnel, lab space, scientific materials, … must be reported.”
• As a “Participant” in the progress report if the person worked on a project for more than a month in any given year. Additionally, the person’s “primary affiliation” is determined by where the work was done for the project: if the individual is affiliated with a foreign organization but worked on the award solely in the U.S., the “primary affiliation” is not foreign; if work was performed while outside of the U.S., the primary affiliation should be noted as foreign.
• As a “Foreign Component” if the individual performed part of the work while in your UMass Chan lab, but also made a significant contribution to the project a from his/her home institution, or any other foreign location (e.g. collecting data at a foreign site, running samples on instrumentation there, and/or will be a co-author on publications arising from the grant).
