Success Stories: NAILG Assisted a Professor/Director of Engineering in Transportation Engineering to EB-1B Approval in Only 15 Days
Client’s Testimonial:
“NAILG has helped me to prepare both I-140 (EB-1B), followed by I-485 Green Card applications, both of which have been approved in 15 days and 2 months, respectively. Their service has always been prompt, professional, and effective. I am thankful to NAILG and my colleague who has recommended me about them.”
On April 1st, 2025, we received another EB-1B (Outstanding Professors and Researchers) approval for a Professor/Director of Engineering in the Field of Transportation Engineering (Approval Notice).
General Field: Transportation Engineering
Position at the Time of Case Filing: Professor/Director of Engineering
Country of Origin: South Korea
State of Residence at the Time of Filing: Iowa
Approval Notice Date: April 1st, 2025
Processing Time: 15 days (Premium Processing Requested)
Case Summary:
Urban congestion. Rising emissions. Cities designed for the past are struggling to serve the future. Where many see intractable problems, our client has consistently provided data-driven solutions.
For over a decade, his work has combined artificial intelligence, simulations, geographic information systems (GIS), and emerging technologies to advance the field of transportation engineering. His research has optimized existing infrastructure, enhanced traffic management, and prepared urban environments for the inevitable rise of autonomous electric vehicles (AVs). His contributions promote not only efficiency and safety but also long-term sustainability, issues central to the future of American cities.
When our client engaged The North America Immigration Law Group (NAILG) to assist with his EB-1B petition, his case presented both a remarkable opportunity and a unique challenge. The breadth and depth of his academic contributions were unquestionable. Yet, the key to success lay in articulating not just scholarly merit but the real-world, national impact of his innovations.
Our client’s record of achievement includes:
- 55 peer-reviewed journal articles (7 first-authored), 22 peer-reviewed conference articles (7 first-authored, 1 accepted for publication), 4 first-authored conference abstracts
- 2,619 citations, ranking him among the top 1% of most highly cited transportation researchers worldwide over the past decade
- Completion of at least 72 peer reviews
- Served as lead guest editor for a special issue and guest editor for some journals
- Research funding from the Abu Dhabi Department of Education and Knowledge (ADEK, formerly known as Abu Dhabi Education Council, ADEC).
Beyond these impressive metrics, His impact is best illustrated by how his models and predictive tools have helped cities and policymakers tackle some of the most pressing transportation challenges. As one leading recommender emphasized:
“With the global population growing exponentially, more people are living in urban areas that were never designed for modern vehicles and population sizes. This has significantly decreased the quality of traffic flow in many capital cities, increased pollution levels, and made public transport less reliable. By this study’s completion, [client] presented his peers and policymakers alike with the tools to predict incoming traffic patterns, allowing them to take the necessary steps to optimize traffic flow, mitigate the impact of consistent traffic on the environment, and reduce the number of hours commuters are stuck in traffic. Given his findings in this study and his consistent history of creating original approaches to traffic management, it is clear his work is of great value to the many American cities with severe local traffic.”
NAILG developed a strategy that moved beyond presenting a list of accomplishments. The petition framed our client’s research within the context of U.S. transportation challenges, urban planning needs, and the broader push toward smart mobility and environmental responsibility. By demonstrating his extraordinary ability, sustained international recognition, and the critical importance of his work, NAILG successfully secured EB-1B approval.
