Case Summary:

Before commencing our attorney-client relationship, we extensively evaluated our client’s credentials to ensure their genuineness. After a thorough assessment, we confirmed that we could help him secure the national interest waiver. Based on our evaluation, we found that our client has a BS in materials and metallurgical engineering and has conducted extensive research on renewable energy generation and storage. His published 5 peer-reviewed journal articles (3 of them first-authored), 3 peer-reviewed conference papers (2 of them first-authored), and 1 US patent application publication have garnered a total of 58 citations, signifying the substantial impact of his work on other scholars in the field. Further, he has conducted 10 peer reviews for highly lauded journals, demonstrating his expertise and knowledge in this area of study.

When he discussed his groundbreaking research in the field of renewable energy generation and storage, establishing new methods and scientific understandings related to developing novel multifunctional energy materials for large-scale energy storage, and high-efficiency low-cost solar cells to improve the performance of advanced renewable energy technologies, we were impressed with the fact that it is of great importance to the United States because it advances the performance and adaptability of renewable energy technologies, which play an important role in reducing global emissions and preventing the worst outcomes of climate change.

Furthermore, we recorded that his research has been financially supported by well-known organizations, exemplifying his ability to continue his work in the United States successfully. The funding he received includes grants from the National Science Foundation (NSF), and the U.S. Department of Energy (DOE), indicating the relevance and importance of his research on a national level.

We took great care in preparing our client’s NIW petition package to showcase his education, experience, expertise, record of publication and citation, and successful research history in his field. Our efforts paid off well as the USCIS approved his I-140 NIW (National Interest Waiver) petition without any request for further evidence. This allows our client, a PhD student from Bangladesh, to continue his valuable research in the United States. We are proud to have contributed to his success and grateful for the opportunity to serve him.
