This is unique to each situation and depends upon specific details surrounding a particular activity. For instance, one model could be that a PI on an NIH grant may have an appointment and a lab at a foreign university. The research being done at the foreign lab is unrelated to the PI’s NIH project. This would not qualify as a foreign component of the NIH research, as the foreign work is not part of the NIH-funded project. However, it is a resource made available to the researcher in support of their research. Therefore, it must be reported as Other Support.
