Case Summary:

A process engineer from Vietnam hired North America Immigration Law Group (NAILG) to file an I-140 EB-2 NIW (National Interest Waiver) petition on his behalf. Our client is an expert in the field of chemical engineering who has worked tirelessly to develop scalable technologies for producing metal oxide nanowires for catalyst, energy storage, and conversion applications. To convince the USCIS of the national importance of his work, we adopted the line of argument that his research ensures improved air quality affected by sulfur and other pollutants. We worked diligently to prove that our client’s findings hold enormous value for reducing pollution that is hazardous to human and environmental health.

In preparing our client’s NIW case, we assessed his credentials to gain a deeper insight into his scientific work and noted his significant achievements. We observed his authorship of 9 peer-reviewed journal articles as well as the 36 times his findings were cited by other researchers in the field.

Our client’s NIW petition was further strengthened by four recommendation letters that were signed by other chemical engineering professionals. These letters discussed the “far- reaching influence” of hisremarkable research efforts. Because these experts had keenly followed our client’s studies, they were well placed to analyze their long-term benefits for the country. One of these recommenders recognized our client as “one of the preeminent chemical engineering researchers working today… Unquestionably a leader in his field, [he] has secured his elite status as a prolific and noteworthy chemical engineering researcher through his research accomplishments, and it is indisputably in the best interests of the United States that his works continue uninterrupted.”

We congratulate our client for securing the national interest waiver and we thank him working with our law firm. Further, we wish him the best as he continues to progress the field of chemical engineering.
