The short answer
Researchers usually show O-1 evidence with publications and citations, peer review, awards and grants, invitations to speak, original contributions backed by expert letters, and high pay or a critical role.
What to know
- Published articles and how often they are cited by others.
- Peer review of other people's work, and membership in selective groups.
- Prizes, grants and fellowships, and press about your work.
- Letters from experts that explain what you did and why it matters.
- Quality and impact matter more than the number of papers.
