We are delighted to share the EB-2 NIW (National Interest Waiver) approval of an associate professor from Sudan. At the time of filing, he was conducting academic research abroad and had already built a strong record of publications, citations, and editorial service. His research addresses the economic consequences of climate change and provides evidence-based strategies for advancing both sustainability and economic development. These accomplishments established him as a well-qualified candidate for NIW approval.

Contribution to National Priorities

The client’s studies explore how climate change affects agriculture, food security, water resources, infrastructure, and public health. By producing actionable data and econometric models, his research equips policymakers with tools to design strategies that mitigate environmental risks while supporting long-term growth.

This work is nationally important. Climate change continues to affect U.S. agriculture, supply chains, and infrastructure, with significant economic consequences. His findings directly support U.S. priorities in sustainability, resilience, and competitiveness.

Scholarly Achievements

The client holds a Ph.D. in economics and has authored 55 peer-reviewed journal articles, 46 of them first- or sole-authored, along with a scholarly book. His work has appeared in respected journals such as Renewable and Sustainable Energy Reviews, Energy Policy, and Journal of Cleaner Production.

He has also completed at least 27 peer reviews for journals, including Economic Modelling and Sustainable Development, and serves as an associate editor for a peer-reviewed economics journal. These roles reflect his standing as a trusted authority in the discipline.

NIW Approval and Outlook

The I-140 NIW petition was filed on January 16, 2024, and approved on September 16, 2025. USCIS determined that his publication record, citation impact, peer review service, and nationally relevant research satisfied the NIW requirements.
