It is possible to prove interdisciplinary research without publications in the EB-2 NIW. Publishing in peer-reviewed journals is only one form of evidence: what truly matters is assembling proof of the quality, originality, and reach of your work, even if it has not appeared in academic journals.

A strong path is letters from recognized experts who are familiar with your work. These letters should highlight your role in projects, the connection across different fields of knowledge, and the unique contribution you brought, and they carry more weight when they come from professionals with authority in the area.

  • Technical reports, project proposals, and patents that demonstrate your active participation.
  • Presentations at conferences, workshops, and seminars, as well as grants and awards received.
  • Participation in review committees and collaborations across institutions and distinct fields.

Each case is evaluated on the totality of the evidence, so build a coherent narrative that connects these elements to the impact of your work. When in doubt, confirm updated guidance from official sources or with a qualified specialist.
