Approval Notice Date: August 26^th, 2025

Processing Time: 1 year, 6 months, 28 days

Case Summary:

We are pleased to share the approval of an EB-2 NIW (National Interest Waiver) petition for a product developer from Kazakhstan. The client’s research focuses on creating sustainable methods in polymer chemistry to minimize the use of harmful solvents and improve adhesive technologies. At the time of filing, he was employed as a product developer, pursuing innovative solutions that reduce environmental impact while advancing industrial applications. His publication record, citation impact, and recognition from peers established him as a strong candidate for NIW approval.

Research with Substantial Merit and National Importance

The client’s proposed endeavor emphasizes developing solvent-free approaches to manufacturing functional adhesive polymers. By eliminating the hazards of organic solvents, his research addresses critical health and environmental concerns while promoting safer and more sustainable industrial processes.

This work aligns directly with U.S. priorities in clean and smart manufacturing. Organic solvent emissions remain a major contributor to pollution and occupational health risks. By offering viable, sustainable alternatives, his research supports initiatives led by agencies such as the Environmental Protection Agency and the Department of Energy and enhances U.S. competitiveness in advanced materials and green technologies.

Well Positioned to Advance the Proposed Endeavor

The client holds a Ph.D. in chemistry and has authored 5 peer-reviewed journal articles, including 2 as first author, published in respected venues such as Science, Advanced Materials, Angewandte Chemie International Edition, Polymer Chemistry, and Langmuir. His work has been cited 45 times by independent researchers across diverse areas of chemistry and materials science. Notably, two of his papers are ranked among the most highly cited for their publication years, with one article in Science placed in the top 0.1 percent.

His contributions have also been recognized through funding from agencies including the National Science Foundation and the Department of Defense, as well as coverage in outlets such as Chemistry World and Chemical & Engineering News. Together, these achievements demonstrate his capacity to continue advancing impactful research in sustainable polymer development.

Recognition from Field Experts

Independent recommenders emphasized the originality and impact of his work.

One expert wrote:

“In conclusion, it is plain to see that [client]’s expertise in chemistry facilitates necessary advancements in the field that are of benefit to the health and well-being of people in the United States.”

Such testimonials reinforced his reputation as a researcher making critical contributions to chemistry and sustainable manufacturing.

NIW Approval and Outlook

The I-140 NIW petition was filed on January 29, 2024, and later upgraded to premium processing. USCIS issued a Request for Evidence (RFE) on April 11, 2025, which we addressed with additional documentation highlighting the client’s scholarly impact and the national relevance of his research. The petition was subsequently approved on August 26, 2025.

With NAILG’s guidance, the client successfully secured NIW approval after overcoming the RFE. He is now positioned to continue his work in the United States, where his research into sustainable polymers and adhesive systems will contribute to cleaner manufacturing practices, protect public health, and support U.S. leadership in materials chemistry and green innovation.
