Client’s Testimonial:
"WeGreened provided very efficient service for my case. The attorneys drafted my documents and replied to my messages promptly. My case preparation and submission were very smooth. I really appreciate what they have done for me.”
On April 23rd, 2026, we received another EB-2 NIW (National Interest Waiver) approval for an Electrical Engineer in the field of Operations Research (Approval Notice).
General Field: Operations Research
Position at the Time of Case Filing: Electrical Engineer
Country of Origin: China
Approval Notice Date: April 23rd, 2026
Processing Time: 1 month, 27 days (Premium Processing Requested)
Case Summary:
As the United States expands renewable energy deployment and battery storage infrastructure, power systems face increasing operational uncertainty and rising demands for reliability. This case involved a Chinese electrical engineer whose work focused on optimization frameworks for power system planning and operation. At the time of filing, the client was working in an energy systems optimization domain in which his research utilized optimization methods to improve how power systems respond to uncertainty, balance electricity demand, and integrate renewable resources more efficiently.
Research Contributions in Operations Research
Rather than focusing on isolated theoretical models, the client’s work addresses practical infrastructure challenges tied to energy reliability and large-scale system operation. His research contributed to optimization methods and their applications in renewable energy deployment and energy device scheduling. These methods help operators make more reliable decisions under changing weather conditions, fluctuating demand, and evolving renewable energy inputs, while supporting the broader transition toward cleaner and more flexible energy systems.
How We Demonstrated the Client’s Significance
The NIW petition focused heavily on the broader infrastructure implications of the client’s work. Rather than presenting his research as purely academic, we connected his optimization models directly to national priorities involving grid resilience, battery storage deployment, renewable energy integration, and energy security. We also demonstrated that he was well-positioned to continue advancing this work through his specialized expertise in optimization, current employment, publication and citation record, extensive peer review activity, federal-funded research, and documented use of his methods by independent researchers working on power system optimization problems.
Academic Contributions and Recognition
The client’s record included over 10 peer-reviewed journal articles, peer-reviewed conference articles, and preprints, 130+ citations, and at least 40 peer reviews for journals and conferences in optimization and power systems engineering. One of his engineering publications ranked among the top 10% most cited papers for its publication year, reflecting meaningful reliance on his work by other researchers in the field. His research was also published in highly regarded power systems journals.
NIW Approval and Outlook
Filed directly with Premium Processing, the I-140 NIW petition was approved on April 23rd, 2026. This approval recognized the national importance of the client’s work in operations research and energy systems optimization and supported his continued contributions to renewable energy infrastructure and grid reliability in the United States.
