Case Summary:
Our team was honored to prepare the EB-2 NIW petition for a distinguished full professor with a Ph.D in chemistry. Committed to I-140 clients, we take a strategic approach, carefully analyzing each case to highlight key strengths and build a compelling petition.
As an expert in the field of inorganic materials chemistry, our client’s proposed endeavor is to continue his research on developing and optimizing nanostructured materials to effectively remove emerging contaminants, microplastics, and radionuclides from water to improve water treatment, desalination, and renewable energy applications.
Furthermore, we demonstrated that his research holds substantial significance, as it provides innovative solutions to improve water sanitation and safeguard public health. His contributions are also essential in addressing environmental challenges, making his work highly valuable to the United States.
To emphasize his expertise, we highlighted his role as a frequent peer reviewer for esteemed industry journals, with at least 7 completed reviews to date.
His impact on the field is further reflected in his extensive body of work, including 81 peer-reviewed journal articles (25 of them first-authored), and 2 co-authored books. His research has garnered 866 citations on Google Scholar, demonstrating its influence within the scientific community.
Additionally, 2 letters from fellow experts were submitted with the petition, offering further validation of his scientific skills and research contributions. One letter specifically noted:
“The results of [Client’s] groundbreaking work, in conjunction with the widespread usage of his research within the scientific community, set him apart as a foremost expert in his field. His research has had real-world benefits in reducing the economic and environmental impact of metal corrosion in commercial and industrial sectors.”
Considering all these significant factors, we are pleased to share that his NIW petition was approved in 17 months and 11 days, despite receiving an RFE.
