To demonstrate that your health research is grounded in robust scientific evidence, the goal is to gather documents that attest to the methodological rigor and recognition of your work by the scientific community. In the EB-2 NIW, this body of evidence helps support the merit of your contribution.

Among the documents that tend to carry weight are:

  • Publications in peer-reviewed journals with a strong reputation in the field.
  • Presentations and abstracts at congresses, symposia, and conferences.
  • Technical reports and studies supported by recognized agencies or institutions.
  • Research protocols, systematic reviews, or meta-analyses that demonstrate solid methodology and adherence to ethical standards.
  • Citations and bibliometric indicators showing the dissemination of your research among other scientists.

Recommendation letters from experts and leaders in the field, affiliated with research institutions or universities, help contextualize the significance of your findings. The transparency and organization of the dossier are just as important as its content.

Since each case is evaluated individually by the competent authority, it is worth verifying the current requirements with USCIS and seeking guidance from a specialist before filing.
