Success Stories: NIW Approved for Iranian Civil Engineering Researcher Advancing Sustainable Pavement Solutions

Client’s Testimonial:

“I would like to sincerely thank you for your assistance and effort in preparing and submitting my case. I am very satisfied with the entire process and the support I have received along the way.”

On May 14^th, 2025, we received another EB-2 NIW (National Interest Waiver) approval for a Civil Engineering Researcher in the Field of Transportation Engineering (Approval Notice).

General Field: Transportation Engineering

Position at the Time of Case Filing: Civil Engineering Researcher

Country of Origin: Iran

Country of Residence at the Time of Filing: Norway

Approval Notice Date: May 14^th, 2025

Processing Time: 11 months, 3 days

Case Summary:

We are pleased to share the NIW approval for a transportation engineering researcher whose work focuses on enhancing the sustainability and cost-efficiency of pavement construction. This petition was filed under the EB2 National Interest Waiver category and was approved after just over 11 months. The client’s proposed endeavor—to develop environmentally friendly road infrastructure through innovative uses of recycled asphalt and bio-based materials—aligns closely with U.S. national priorities on infrastructure modernization and environmental sustainability.

Research Impact on National Infrastructure and Environmental Policy

Our client’s research aims to transform traditional road construction by using high percentages of recycled asphalt pavement (RAP) and natural rejuvenators. His innovative approaches enhance the durability and reduce the environmental footprint of pavements, supporting U.S. goals to reduce greenhouse gas emissions and extend the life of infrastructure.

The endeavor also addresses critical challenges such as waste management, emissions from asphalt production, and the depletion of natural resources, providing a sustainable path forward for one of the country’s most expansive public assets: its road network.

Demonstrated Scientific Merit and Influence

To substantiate the petition, we highlighted the client’s impactful research and thought leadership in transportation engineering, including:

● Citation Count: 1,051 citations, with multiple papers ranked among the top 0.1%, 10%, and 20% most-cited engineering papers for their respective years of publication.
● Publications: 16 peer-reviewed articles (including 7 first-authored and 1 co-first-authored papers) published in top journals such as Construction and Building Materials and Journal of Materials in Civil Engineering.
● Peer Review Work: 35+ completed peer reviews for leading journals and conferences in the field, demonstrating his expert status.

His research has been widely referenced by global researchers and institutions, including studies published by academic institutions and departments of transportation, indicating real-world application and influence.

Support from Independent Experts

The petition was supported by two recommendation letters, including multiple independent experts. These letters emphasized the originality and broad applicability of the client’s work, specifically its significance in promoting sustainable construction methods and contributing to national infrastructure and environmental policy.

One letter noted:

“His work presents a transformative pathway for incorporating recycled materials in road infrastructure without compromising durability, and has informed both academic research and industry practices.”

A Sustainable Vision for the Future

The petitioner’s future work will continue to explore bio-based rejuvenators and environmentally friendly fillers in asphalt mixtures, as well as cost performance analysis of infrastructure projects using advanced modeling techniques. These goals directly support U.S. interests in technological innovation, sustainable development, and critical infrastructure advancement.

A Well-Earned Success

Through careful documentation and strategic presentation of the petitioner’s expertise, publications, influence, and alignment with national goals, we secured a favorable outcome from USCIS. This approval stands as a testament to both the client’s outstanding contributions and the strength of our petition strategy.

We congratulate our client on this important milestone and are excited to support his continued work advancing sustainable transportation engineering in the United States.
