On December 11th, 2025, we received another EB-2 NIW (National Interest Waiver) approval for a Postdoctoral Associate in the field of Environmental Engineering (Approval Notice).
General Field: Environmental Engineering
Position at the Time of Case Filing: Postdoctoral Associate
Country of Origin: China
State of Residence at the Time of Filing: Texas
Approval Notice Date: December 11th, 2025
Processing Time: 2 months, 9 days (Premium Processing Upgrade Requested)
Case Summary:
The petition framed our client’s proposed endeavor as a practical rethinking of wastewater in modern infrastructure. Instead of treating wastewater as a problem to manage and discharge, her work treats it as a resource that can be engineered for nutrient recovery, energy production, and community health support. Her approach emphasizes integration, applying these strategies across critical settings, including institutional and industrial facilities, wastewater treatment plants, and agricultural systems, to strengthen economic sustainability, environmental protection, and public health.
We demonstrated that our client’s background supported that framing with clear technical credibility and research momentum. She holds a Ph.D. and an M.S. in Civil and Environmental Engineering and was working as a Postdoctoral Associate at the time of filing. She has published 7 peer-reviewed journal articles, including 5 first-authored papers, and her work has received 49 citations, reflecting early independent engagement with her findings and methods.
The national importance argument was reinforced by substantial, objective support from U.S. institutions. Her research received funding from the Centers for Disease Control and Prevention (CDC), the U.S. Department of Agriculture (USDA), and the U.S. Department of Energy (DOE). This demonstrated cross-sector relevance, linking wastewater innovation to public health readiness, resilient infrastructure, and sustainable resource management.
Expert testimony highlighted the practitioner-facing impact of her research, with one recommender noting:
“[Client]’s research has significantly strengthened the tools available to public health practitioners in the United States. Her success in these projects solidifies her unique expertise in molecular assay development, surveillance pipeline optimization, and environmental monitoring.”
USCIS approved the NIW petition on December 11th, 2025, concluding the process in just 2 months and 9 days via Premium Processing. NAILG (North America Immigration Law Group) presented the endeavor, funding support, and track record as a coherent NIW case showing both national importance and our client’s strong positioning to continue advancing integrated wastewater solutions in the United States.
