Client’s Testimonial:
“I filed my I-140 under the EB2-NIW category with NAILG. Although I do not yet hold an advanced degree, we pursued the exceptional ability criteria, which presented a more challenging case. It took approximately 4 months to fully compile the petition, as we needed extensive documentation and evidence to present a compelling case. With no premium processing, I received my I-140 approval in under 12 months without any requests for further evidence. I was very pleased with this outcome! Throughout the process, NAILG demonstrated professionalism, timely communication, strong support, and sound legal guidance. I would highly recommend them to anyone seeking U.S. permanent residency!”
On May 27th, 2025, we received another EB-2 NIW (National Interest Waiver) approval for a PhD Student in the Field of Chemical Engineering (Approval Notice).

Case Summary:
At the forefront of sustainable fuel development, our client is redefining how the U.S. can transition to a cleaner, circular carbon economy. As a chemical engineering researcher, his proposed endeavor focuses on designing a comprehensive workflow that integrates theoretical modeling with experimental data to accelerate the discovery of porous catalytic materials. These materials play a critical role in converting low-value resources, such as waste methane, into high-value fuels and chemicals, a process essential for reducing greenhouse gas emissions and combating climate change.
Turning Waste into Fuel: A Climate-Smart Approach
Our client’s work directly addresses two urgent national priorities: decarbonizing the energy sector and advancing materials science for clean technology. His methods contribute to the efficient conversion of industrial waste and underutilized feedstocks into valuable chemical products, helping minimize waste, cut emissions, and create scalable, sustainable alternatives to fossil fuels. Through systematic, data-driven design and machine learning tools, he provides a novel, cost-effective framework for discovering catalytic materials essential to the success of emerging green technologies.
Nationally Funded, Broadly Recognized
His research has been backed by some of the most competitive federal agencies, including the NSF, the DOE, the DARPA, and the ONR.
This level of funding underscores the scientific rigor, strategic value, and national relevance of his work in catalysis and clean energy materials.
A Strong Record of Scholarly Impact
He has made substantial contributions to the academic field with:
● 5 peer-reviewed journal articles (3 first-authored), 7 conference abstracts (2 first-authored), 3 preprints
● 48 citations to date
As one expert wrote:
“Overall, [client] is conducting cutting-edge research into the incorporation of machine learning to facilitate efficient and streamlined high-throughput computational studies that rely on large-scale quantum chemistry calculations. The high quality of his research in assessing the productivity of these calculations is clearly shown by his mitigation of wasted computational resources and his publications in highly influential scholarly journals. [client]’s research in the chemical engineering field is undoubtedly of benefit to both the U.S. and the global research communities.”
Legal Strategy for National Interest Recognition
To secure his National Interest Waiver, our client partnered with the North America Immigration Law Group (NAILG), which skillfully positioned his research as vital to national energy innovation, climate action, and advanced manufacturing. By highlighting both the technical excellence and national applicability of his work, NAILG crafted a persuasive petition that clearly demonstrated how his continued presence in the U.S. supports federal environmental goals and strengthens the country’s scientific leadership. His NIW approval marks a significant step forward in enabling transformative contributions to clean energy and sustainability.
