This powerful endorsement from an expert captures the significance of our client’s contributions.

We emphasized how this work tackles urgent environmental challenges, including plastic waste management and greenhouse gas emissions reduction, while supporting national goals for renewable energy development and economic growth in the renewable sector.
To build a compelling case, we strategically highlighted the client’s exceptional credentials: more than 10 peer-reviewed journal articles, conference proceedings, and book chapters. The client’s research has garnered 115+ citations during the submission of his petition. We also emphasized research funding from the U.S. Department of Agriculture, demonstrating institutional recognition of the work’s national significance. The petition also included 2 very strong recommendation letters from experts in the field.
We are pleased to report that the NIW petition was approved within approximately 11 months. It has been an honor to support this researcher, and we extend our sincere best wishes for continued success in advancing sustainable materials science for the benefit of the United States.
