Is it possible to prove health impact without conducting clinical trials?

The EB-2 NIW visa requires the applicant to demonstrate, among other requirements, that their work will have a positive and nationally relevant impact for the United States. In the health field, this may mean presenting evidence of how their contributions improve or transform practices, policies, or treatments.

It is important to understand that proving health impact is not necessarily limited to conducting clinical trials. Many health professionals and researchers are able to demonstrate the relevance of their studies and innovations through publications, public policy reviews, epidemiological studies, statistical analyses, and other forms of scientific evidence. For example, research showing the effectiveness of new diagnostic methods or interventions based on retrospective data, meta-analyses, or observational studies can be highly valuable in evidencing improvements in public health or clinical practice.

These publications, when well-founded and widely cited, can be considered robust elements to demonstrate national impact, provided evaluators see a clear connection between the applicant’s work and the benefits to the United States population. Another point to consider is that, to strengthen any immigration petition, it is crucial to gather all supplementary documentation that helps evidence the importance and impact of the work. Recommendation letters from renowned experts in the field, whose track record and international recognition are consistent, can reinforce the narrative that the work exerts a positive and significant influence on health, even without the conduct of clinical trials.

Always remember the importance of carrying out this process in compliance with United States immigration laws and seeking information from reliable sources. Beware of door-to-door promises or shortcuts assuring results. Obtaining a detailed analysis and building a robust dossier depends on a thorough study of the available evidence, without relying exclusively on a single method, such as clinical trials.
