Success Story: I-140 NIW Approval Without an RFE for a Biostatistics Expert Advancing Data-Driven Clinical Research
Client’s Testimonial:
"It was a pleasure working with Chen Immigration Group on my NIW petition. I truly appreciate their professional support, clear communication, and thoughtful guidance. Thank you for all your help!”
On March 9th, 2026, we received another EB-2 NIW (National Interest Waiver) approval for an Assistant Biostatistician in the Field of Biostatistics (Approval Notice).
General Field: Biostatistics
Position at the Time of Case Filing: Assistant Biostatistician
Country of Origin: China
State of Residence at the Time of Filing: Virginia
Approval Notice Date: March 9th, 2026
Processing Time: 1 month, 6 days (Premium Processing Upgrade Requested)
Case Summary:
The client’s I-140 NIW approval reflects a strong showing that her work in biostatistics serves important U.S. healthcare needs. With an M.S. in biostatistics and data science, the client proposed to continue applying advanced biostatistical and data science methodologies to improve the design, analysis, and interpretation of medical and public health research. The petition framed this endeavor as nationally important because a stronger study design and more reliable interpretation of health data can improve diagnostic accuracy, treatment effectiveness, and patient outcomes across the healthcare system.
The case also showed that the client is well-positioned to advance this work. She is currently employed as an assistant biostatistician at a major healthcare organization, where she supports clinically focused research and data-driven healthcare studies. Her record included 15 peer-reviewed journal articles and 10 abstracts, which the petition did not present as numbers alone, but as evidence of sustained contribution to active medical and public health research questions. The publication record was especially persuasive because it demonstrated both productivity and continued engagement in translational, patient-centered research.
Her citation record further supported the case. The client’s published work had received 30 citations, and the petition strengthened that evidence by explaining that several of her articles performed notably well compared with field and year benchmarks. That type of comparative citation analysis is often more meaningful to an adjudicator than a raw total because it helps show that other researchers are not merely noticing the work, but relying on it.
The petition also demonstrated significance through the substance of the client’s research. Her work contributed to efforts involving treatment optimization, emergency and cardiac care, and evidence-based clinical decision-making. In other words, the case did not argue that the client was important simply because she had degrees or publications. It argued that her analytical methods strengthen the scientific foundation of healthcare research and help translate evidence into practice more effectively. That was central to showing both national importance and why waiving the job offer requirement would benefit the United States.
