Case Summary:
We were hired to represent a sustainable energy consultant from Nigeria, who filed an I-140 National Interest Waiver (NIW) petition. The client’s work involved developing and implementing digital technologies through analytical or numerical modeling and simulation to support effective nuclear waste disposal and the transition to sustainable energy production.
Part of our job was to demonstrate that his achievements; an M.Sc. in petroleum engineering and project development, is a member of the professions holding an advanced degree. Also, his continued research is critical to the goal of achieving and preserving the United States’ technological leadership.
We began by laying out a solid petition packet by gathering all the pertinent information required to lead him to the NIW victory. We listed the following in his NIW petition package:
- We highlighted that his research work is of great importance because it drives economic growth and improves nuclear waste management. His use of digital technologies to support the world’s transition towards sustainable energy production adds value to the global power generation market.
- In addition, we emphasized his thriving track record and influential impact on the field. His research has been published in some of the top publication venues in his field, resulting in 6 peer-reviewed journal articles (1 of them first-authored) and 1 firstauthored peer-reviewed conference paper. His published papers have accumulated 37 citations, demonstrating his significant influence on his fellow scholars’ comprehension of topics in his chosen field.
- Also, his study has received funding from the Institute for Korea Spent Nuclear Fuel, and the National Research Foundation of Korea. Therefore, this serves as evidence that our client’s work benefits society by enhancing sustainable energy science and tackling essential barriers to the safe disposal of nuclear waste.
We are glad to mention that our client has a proven track record of successful research in an area that significantly furthers U.S. interests. Therefore, his contributions are highly valuable and would benefit the United States, even if there were other qualified U.S. workers available. Our client’s proposed endeavor aims to tackle critical issues related to mitigating the harmful effects of climate change and developing strategies for the efficient management of spent nuclear fuel. Since he is uniquely well-positioned to pursue this work given his experience, leadership, and expertise in the field, USCIS approved his NIW petition only 7 days after we submitted his case.
We truly appreciate our client’s support throughout this process and wish him luck in his future endeavors.
