Case Summary:

With the guidance of the North America Immigration Law Group (NAILG), a petroleum engineering expert has secured EB-2 NIW approval for work that directly addresses some of the most pressing challenges in U.S. energy security and sustainable resource management. His proposed endeavor focuses on creating a highly accurate predictive model for gas transport in shale and tight gas formations, enabling improvements in carbon dioxide and hydrogen storage, natural gas production, and enhanced gas recovery. In parallel, he is advancing a modified lithium-aluminum layered double hydroxide adsorbent through doping engineering to significantly boost lithium extraction efficiency from produced shale water – an innovation with clear implications for renewable energy storage and electric vehicle technologies.

His research not only strengthens the U.S.’s position in the clean energy transition but also provides critical insight into lithium extraction techniques that combine adsorption and electrochemical methods. These advances allow users to recover lithium more efficiently, promoting the development of high-performance rechargeable batteries and ensuring the reliability of renewable energy infrastructure. Recognizing the national importance of this work, the National Science Foundation (NSF) has provided competitive funding to support his efforts.

In preparing the NIW petition, NAILG built a case that presented both the technical significance and the national relevance of his contributions. We emphasized the dual impact of his research, advancing sustainable energy technology while reinforcing U.S. leadership in global energy innovation, and ensured that the evidence of his work’s importance was clear, consistent, and compelling to USCIS.

His record of achievement reflects years of rigorous research and scholarly contribution, including five peer-reviewed journal articles (two first-authored), two conference papers (one first-authored), at least three completed peer reviews, and 135 citations to date. These accomplishments, paired with the practical applications of his work, provided strong evidence that his continued research would serve the U.S. national interest.

With NIW approval now in hand, he is poised to continue his pioneering work in the United States, pushing the boundaries of both energy extraction and storage. NAILG is proud to have played a role in achieving this result and looks forward to seeing how his research will shape the future of sustainable technology.
