Success Story: From Problematic Soils to Stronger Infrastructure, NIW Approval for a Bangladeshi Civil Engineering Researcher
Client’s Testimonial:
"I had a great experience working with Chen Immigration on my NIW case. Their team did an excellent job preparing my case in 2024, ensuring every detail was carefully structured and well-documented. What impressed me most was their ability to build a strong petition that remains solid even under the current challenging timeline. They were highly responsive, organized, and consistently met deadlines throughout the process. I truly appreciate their professionalism and would highly recommend them to anyone pursuing an NIW petition.”
On March 24th, 2026, we received another EB-2 NIW (National Interest Waiver) approval for a Ph.D. Candidate in the Field of Civil Engineering (Approval Notice).

Country of Origin: Bangladesh
State of Residence at the Time of Filing: Arizona
Approval Notice Date: March 24th, 2026
Processing Time: 24 months, 4 days (Premium Processing Requested)
Case Summary:
“By providing practical and environmentally friendly solutions to overcome challenges associated with problematic soils, [Client] has made immense contributions to the sustainability of civil infrastructure.”
This observation from a recommendation letter captured the heart of this NIW case. At North America Immigration Law Group (Chen Immigration Law Associates), we worked to show that this was not simply a case about soil mechanics in the abstract. It was about safer roads, more resilient infrastructure, and sustainable engineering solutions with clear value to the United States.
The Challenge Beneath the Surface
The client’s proposed endeavor focused on developing energy-efficient and environmentally friendly chemical, mechanical, and bio-mediated solutions to alter soil properties—particularly to reduce frost heave and thaw weakening in frost-susceptible soils. In practical terms, the work aims to improve the resilience of civil infrastructure construction in a cost-effective and environmentally responsible way.
Why the Work Mattered Nationally
We emphasized that this endeavor has significance far beyond a single lab or project. The petition connected the research to major national concerns involving roadway safety, infrastructure degradation, climate-related damage, and the enormous economic costs of underperforming infrastructure.
The case also benefited from evidence that the research had already attracted funding from organizations with clear public-interest missions, including the U.S. Department of Defense’s Army Research Laboratory, the Hawthorn Foundation, and the National Science Foundation. That support reinforced the national importance of the work and showed that relevant institutions saw value in these soil-stabilization strategies.
A Record That Showed More Than Promise
Although still in the Ph.D. stage, our client had already built a record that showed both originality and momentum. The case included:
- 3 peer-reviewed journal articles, 5 conference publications
- 15 citations
- 4 completed peer reviews
Together, these indicators helped establish that this was a researcher already contributing to the field in concrete ways. The petition also highlighted several lines of research that made the client’s profile especially compelling: investigating how extreme climatic conditions affect soil stability; developing targeted chemical stabilization methods to reduce weather-induced structural damage; integrating sustainable and recycled materials to improve mechanical properties; and exploring innovative biological approaches to control physical degradation in demanding environments.
The Approval
This case illustrates how an NIW petition can successfully connect specialized civil engineering research to the larger public interest. We helped present a persuasive case for our client, resulting in a successful outcome.
