Success Story: Computational Modeling Expert Secures I-140 NIW Approval for Research Advancing Cleaner Engine Technologies
Client’s Testimonial:
"The immigration team was incredibly professional on my I-140 preparation. In addition, they are responsive to answering any questions about immigration, including my current case, timeline, etc. I highly recommend their service.”
On May 4th, 2026, we received another EB-2 NIW (National Interest Waiver) approval for a Post-Doctoral Researcher in the Field of Computational Modeling (Approval Notice).
General Field: Computational Modeling
Position at the Time of Case Filing: Post-Doctoral Researcher
Country of Origin: Taiwan
State of Residence at the Time of Filing: Illinois
Approval Notice Date: May 4th, 2026
Processing Time: 4 months, 22 days (Premium Processing Upgrade Requested)
Case Summary:
North America Immigration Law Group was pleased to help secure an I-140 NIW approval for our client, an expert in computational modeling whose work focused on applying computational fluid dynamics simulations, Lagrangian-Eulerian frameworks, and machine learning to investigate multiphase flow in automotive and aerodynamic sprays. At the time of filing, the client was conducting research in the United States, continuing work aimed at reducing cold-start emissions and developing predictive tools that can support engine design and optimization.
The petition presented the client’s proposed endeavor as both technically specialized and nationally important. Rather than treating the work as a narrow academic project, we demonstrated how the client’s research supports cleaner transportation, improved fuel efficiency, stronger engine performance, and the development of low-emission propulsion technologies. We also emphasized that the client’s computational tools could assist original equipment manufacturers by improving how complex fuel spray behavior is modeled and predicted.
To show that the client was well-positioned to advance this endeavor, we organized the evidence around a record of sustained research productivity and independent recognition. The petition documented 6 peer-reviewed journal articles, including 4 first-authored articles, 3 first-authored peer-reviewed conference articles, 7 first-authored abstracts, 1 first-authored preprint, and 1 technical report. The client’s published work had received 49 citations, which we contextualized as evidence that other researchers had relied on the client’s findings and methods in related investigations. We also noted that two of the client’s papers ranked among the top 10% most-cited articles in their field and year, helping show that the citation record reflected meaningful peer reliance rather than citation numbers alone.
The petition further highlighted the client’s peer review activity and the fact that the client’s research had received support from a major U.S. government funding source, the U.S. Army Research Laboratory. We explained that this funding reinforced the practical importance of the client’s work in advancing energy, propulsion, and performance technologies relevant to national interests.
By connecting the client’s publication record, citation impact, peer recognition, government-funded research support, and ongoing work in computational modeling, we demonstrated that the client’s continued research would benefit the United States and that a waiver of the job offer and labor certification requirements was justified. We congratulate our client on this I-140 NIW approval and wish them continued success in advancing cleaner and more efficient transportation technologies in the United States.
