The short answer
PhD students use publications and citations, recommendation letters, a clear research plan, grants and awards, and proof of how their work helps a national priority. Being a student does not by itself prove it.
What to know
- Publications, citations, patents and presentations.
- Letters from experts who know your work, including independent ones.
- A plan describing what you will do in the U.S. and why it matters.
- Funding, awards, software or datasets used by others.
- Show your record is strong compared with others in the field.
