Success Stories: Chinese PhD Student Earns NIW Approval After Overcoming RFE for Precision Medicine Research
Client’s Testimonial:
“I worked with the North American Immigration Law Group on my EB2 NIW petition. Their professional guidance greatly streamlined the preparation process and was instrumental in the approval of my case.”
On September 19th, 2025, we received another EB-2 NIW (National Interest Waiver) approval for a PhD Student in the field of Epidemiology (Approval Notice).
General Field: Epidemiology
Position at the Time of Case Filing: PhD Student
Country of Origin: China
State of Residence at the Time of Filing: Florida
Approval Notice Date: September 19th, 2025
Processing Time: 1 year, 9 months, 1 day
Case Summary:
We are pleased to share the EB-2 NIW (National Interest Waiver) approval of a PhD student from China. Her research centers on discovering disease mechanisms to enable personalized diagnostics and treatments. At the time of filing, she was conducting academic research on nationally relevant health problems, supported by a record of peer-reviewed publications and independent citations that demonstrated her impact.
Transforming Healthcare Through Data-Driven Research
The client’s proposed endeavor is rooted in precision medicine. She is working to advance understanding of cardiometabolic disease, chronic kidney disease, COVID-19 risk factors in vulnerable populations, and rare pediatric autoimmune disorders. By applying multi-omics analysis, bioinformatics, causal inference, and machine-learning methods, she is developing predictive models and biomarker-based diagnostic strategies that can guide more tailored and cost-effective treatments.
Her work carries significant weight in the U.S. healthcare landscape. Cardiovascular and metabolic conditions remain leading causes of death and disability, and addressing them is a national priority. By offering earlier diagnoses and targeted therapies, her research directly supports U.S. goals of reducing chronic disease burden, improving outcomes, and strengthening health equity.
Academic Contributions and Recognition
The client holds advanced training in medicine and public health. She has authored four peer-reviewed journal articles, including a first-authored study, published in respected journals such as Kidney International, Diabetes Care, and JACC: Cardiovascular Interventions. Her work has been cited 127 times by independent researchers, with several articles ranking in the top 10–20 percent of most cited clinical medicine papers for their publication years.
Her studies on lipidomic biomarkers for diabetes and chronic kidney disease, as well as investigations into coronary physiology and wall shear stress, have been widely referenced by experts in cardiology and nephrology. The adoption of her findings in diverse medical contexts demonstrates the influence and practical value of her contributions.
Expert Support
Letters from independent experts strongly endorsed the client’s achievements.
One recommender stated:
“[Client]’s productive research output and publications are a testament to her significant contributions to the field of epidemiology.”
This endorsement reflects the high regard of her peers and confirms that her work is both scientifically influential and directly relevant to improving public health.
Approval and Outlook
Her I-140 NIW petition was filed on December 18, 2023. USCIS issued a Request for Evidence (RFE) on April 25, 2025, but after additional evidence was submitted to verify her address, the case was approved on September 19, 2025.
With NAILG’s support, the client successfully secured NIW approval. She is now positioned to continue advancing biomarker-driven diagnostics and predictive modeling tools that will shape the future of precision medicine in the United States.
