While some of the fellowship's most frequently asked questions are addressed below, one should refer to the comprehensive FAQ within the online system — accessible during the October-through-January open period — for a more extensive review of topics related to the DOE CSGF application and its various components.


No. You must be a U.S. citizen or lawful permanent resident to apply for the DOE CSGF.

At time of application, you cannot have completed more than one year of full-time graduate work towards your Ph.D. Please review eligibility criteria and additional FAQs on this subject, or contact us with specific questions.

You can apply, but you may have to give up your current fellowship if you receive a DOE CSGF offer. The DOE CSGF cannot be accepted concurrently with another federal fellowship.

Having a master's degree does not affect your application to the fellowship as long as you plan to attend a different university for your doctoral studies.

Program of Study (POS)

You can attend any accredited U.S. university offering a Ph.D. during the fellowship period. Read about the program of study requirement.

If awarded the fellowship, you will be asked to provide a new POS with your selected university that must be approved as a condition of acceptance. Please contact the DOE CSGF to provide an update to university selections after your application has been submitted.

Please assemble a POS for your top-choice institution. If you are offered a DOE CSGF award and ultimately enroll at a different institution, you will be required to submit a new POS at that time.

Ideally, the graduate advisor at your preferred university will review your POS. If this is not feasible, please have your current undergraduate advisor review your proposed POS.

Application Status & Submission

Yes, you can save your application and work on it any time.
