Case Summary:
Drawing on our extensive experience and proven track record of over 32,000 successful cases, our expert team recently secured National Interest Waiver approval for a senior statistical data analyst from China in the field of biostatistics.
The client, who holds an M.S. in biostatistics, came to us with strong credentials but faced the common challenge many specialized researchers encounter: articulating how technical work serves compelling national interests. Our strategic approach transformed this challenge into a compelling petition. The petition was approved after 21 months without the issuance of a Request for Evidence (RFE).
Research with Substantial Merit and National Importance:
In preparing the NIW petition, North America Immigration Law Group (NAILG) emphasized that the client’s research is vital to improving the accuracy, efficiency, and equity of healthcare systems through the development of robust study designs and analytical methods for diverse biomedical data. Her work supports medical researchers by enabling them to conduct statistically sound studies that yield reliable results—ultimately shaping clinical guidelines, public health strategies, and evidence-based interventions.
The client received three recommendation letters. A strong recommendation letter from an expert has highlighted the real-world impact of the client’s work:
“Given [The Client]’s consistent track record of accomplishments, demonstrated by [The Client]’s extensive experience at esteemed institutions and ongoing research achievements, there is no doubt that [The Client] is prominent in the field of biostatistics. As such, [The Client]’s research efforts must continue unabated.”
NAILG showcased the client’s academic and professional excellence through an impressive record of scholarly achievements and research impact, including:
-
11 peer-reviewed journal articles (1 first-authored), published in top-tier journals.
-
A total of 62 citations, demonstrating broad recognition and use of her findings by independent researchers worldwide.
-
Research supported by major funding agencies, including the National Heart, Lung, and Blood Institute and the National Institutes of Health (NIH).
The Result
This clean approval reflects our comprehensive initial submission, which anticipated potential concerns and proactively addressed them with authoritative evidence and strategic positioning. For researchers in biostatistics, data science, and healthcare fields, this case demonstrates that specialized technical work can meet the demanding NIW standard when properly connected to national priorities and supported by objective evidence. It has been an honor to support this exceptional researcher, and we extend our sincere best wishes for continued success in advancing healthcare research in the United States.
