On November 29th, 2025, we received another EB-1A (Alien of Extraordinary Ability) approval for a Battery Modeling Engineer in the Field of Electrical Engineering (Approval Notice).
General Field: Electrical Engineering
Position at the Time of Case Filing: Battery Modeling Engineer
Country of Origin: China
State of Residence at the Time of Filing: Michigan
Approval Notice Date: November 29th, 2025
Processing Time: 3 months, 28 days (Premium Processing Upgrade Requested)
Case Summary:
At NAILG, we recently secured an EB-1A approval for an electrical engineering researcher whose work is transforming the reliability and safety of modern energy systems. The petition utilized a premium processing upgrade and, although USCIS issued a Request for Evidence just 20 days after filing, NAILG prepared a targeted response that addressed each concern clearly. The case was approved a little under four months after filing, confirming that the client met the high bar for extraordinary ability.
Our client holds a Ph.D. in Electrical Engineering and is recognized for sophisticated investigations in modeling, fault diagnostics and prognostics, and algorithm development. His research focuses heavily on lithium-ion battery systems and battery-powered equipment, providing tools to understand failure modes, predict remaining useful life, and ensure safe operation. These methods are crucial for electric vehicles, renewable energy storage, and other advanced power systems where reliability and safety are non-negotiable.
A major strength of the case was his publication and citation record. He has documented his work in 15 peer-reviewed journal articles (including 4 first-authored and 1 corresponding-authored paper), 2 first-authored accepted conference articles, 1 first-authored journal article under review, and 4 conference articles (3 first-authored). His research has been cited 504 times, demonstrating sustained influence and showing that independent researchers around the world rely on his models and algorithms to drive their own advances in diagnostics, prognostics, and system reliability. He is an IEEE senior member, and his work also received funding from such prestigious organizations as the National Aeronautics and Space Administration’s Small Business Innovation Research (NASA SBIR) program.
NAILG also emphasized the client’s role as a recognized authority in evaluating the work of others. He has completed at least 40 peer reviews for respected journals and was invited to serve as a Guest Editor for a Special Issue on lithium-ion battery modeling and safety. Peer review and editorial leadership are responsibilities reserved for trusted experts, and his record in these roles provided strong, objective evidence that the field looks to him for judgment on cutting-edge research.
Throughout the petition, letters from independent experts reinforced the significance of his contributions. One recommender concluded that “[Client]’s expertise is indispensable, providing significant advancements in battery-powered systems, particularly in electric vehicles, renewable energy storage, and energy efficiency.” This testimony, combined with his publication impact and leadership in peer review, helped establish that his work has major practical implications for cleaner transportation, resilient energy grids, and safer power electronics.
By organizing this evidence into a coherent EB-1A framework and addressing USCIS’s comments point-by-point, NAILG demonstrated that the client is among the small percentage who have risen to the top of the field, with sustained acclaim and major contributions in electrical engineering. Overcoming the RFE and winning approval confirmed not only the strength of his record but also his ongoing potential to enhance battery-powered systems that support U.S. innovation, energy security, and technological competitiveness.
