Success Story: Our Firm Helped a Chinese Research Scientist Secure NIW Approval Without RFE

Client’s Testimonial:

“Wegreened helped me with my NIW application. The whole process is efficient and smooth. All my questions in the system got answered in time, and the guidance helped me prepare my documents, resulting in an approval without RFE.”

On August 12^th, 2025, we received another EB-2 NIW (National Interest Waiver) approval for a Research Scientist in the Field of Fluid Mechanics (Approval Notice).

General Field: Fluid Mechanics

Position at the Time of Case Filing: Research Scientist

Country of Origin: China

State of Residence at the Time of Filing: Tennessee

Approval Notice Date: August 12^th, 2025

Processing Time: 13 months, 10 days

Case Summary:

We are pleased to share the success story of an EB-2 NIW (National Interest Waiver) approval granted to a mechanical engineering expert whose research focuses on fluid mechanics. At the time of filing, the client was serving as a CFD research scientist and had already produced impactful work on computational fluid dynamics (CFD) approaches to improve air lubrication systems for maritime applications. His work advances energy efficiency in shipping and contributes to reducing reliance on fossil fuels and lowering carbon dioxide emissions.

Research Focus and Contributions:
The client’s proposed endeavor centers on pioneering CFD-based designs for air lubrication systems that minimize drag on vessel hulls, thereby enhancing maritime efficiency. His research specifically involves developing advanced models for two-phase turbulent flow simulations, algorithms to predict the behavior of air films and bubbles, and multiphysics simulations to optimize system manufacturing. These contributions provide crucial insights for strengthening the environmental and economic sustainability of maritime transportation, which supports a substantial portion of global trade.

Research Impact and Scientific Contributions:
To establish the national significance of the client’s work, we highlighted several key achievements:

Publications: Authored 6 first-authored peer-reviewed journal articles and 1 peer-reviewed conference paper published in leading venues in fluid mechanics.
Citations: His published work has been cited 32 times according to Google Scholar, underscoring the recognition and adoption of his research across the scientific community.
Funding: His work has been supported by major U.S. government funding agencies, including the National Science Foundation (NSF) and the Department of Energy (DOE), underscoring its recognized national importance.

Support from Experts in the Field:
The petition was further strengthened by four recommendation letters submitted from distinguished experts. These letters praised the client’s innovative approaches to fluid mechanics, highlighting how his findings have advanced both scientific knowledge and industrial practice. One letter stated:

“In light of [Client’s] exemplary record and achievements, it is clear that he is a leader in the field of fluid mechanics.”

Well Positioned to Advance the Proposed Endeavor:
With a Ph.D. in mechanical engineering and a proven record of impactful research, the client has demonstrated the expertise, experience, and technical skills needed to drive forward this nationally important work. His previous investigations into optical control of fluid flow, nanoparticle sintering, and droplet dynamics have already provided solutions to complex engineering challenges, and his ongoing efforts will further support U.S. goals of sustainability, economic efficiency, and technological leadership in the maritime sector.

NIW Approval and Outlook:
Approved in August 2025, this NIW petition recognized the client’s substantial contributions and his potential to continue producing research of national importance. NAILG is proud to have successfully represented this client in his NIW petition, and we look forward to seeing his continued impact in advancing fluid mechanics research and promoting sustainable maritime technology.
