General questions about choosing research groups and training at NIH

We strongly recommend that you read information on finding research groups in the NIH Intramural Research Program before you select being the process of finding a research group and interviewing for positions.

Some organizations will fund research for intramural fellows. We have compiled a list of those we know will accept (and will not accept) applications from NIH trainees and fellows: Funding Opportunities for NIH Intramural Fellows. If you have questions, reach out to both the funder and the IC training director or IC scientific director to confirm that you are eligible to apply and that you will be allowed to accept funding if successful.

The OITE supports trainees and fellows in all NIH ICs, at all training levels and on all NIH campuses. You can learn about what we offer by visiting other areas of this website including:

We have some information on planning your move and finding housing resources. The NIH does not offer dormitory housing.

NIH trainees and fellows may not be appointed to work remotely; however, you may be able to work from home (telework) on a limited basis.

NIH interns must work in a research group in the Intramural Research Program. If you want to work in administrative or policy positions at NIH, apply to the NIH Pathways for Students and Recent Graduates Program operated by Human Resources.

Questions about applying to the Undergraduate Scholarship Program (UGSP)

No. UGSP Scholars must be U.S. citizens or permanent residents.

Successful UGSP applicants are well-rounded students with research experience, a strong academic record, and a commitment to extracurricular activities.

Disadvantaged background means that your financial aid office has certified you as having "exceptional financial need" (EFN), as defined by the federal government. Your university’s financial aid officer will need to certify your eligibility.

The payback is the yearlong service obligation required by the UGSP in exchange for the scholarship award. UGSP also refers to trainees completing this obligation as paybacks.

UGSP scholars can defer their post-graduation service obligation while completing a graduate or medical program leading to a doctoral degree. Deferments cannot be granted for training conducted by any entity that imposes another service obligation, such as a branch of the U.S. Armed Forces.
