General Field: Electrical Engineering

Case Summary:

A graduate assistant with a record of completing 70 peer reviews for several highly acclaimed journals and conferences approached the North America Immigration Law Group to help him file I-140 NIW (National Interest Waiver) petition. Since peer review is considered “the only widely accepted method for research validation” with publishers relying on the peer review process “to uphold the quality and validity of individual articles and the journals that publish them”, we knew we had a solid case at hand. Given the specifications of USCIS for NIW cases, his consistent peer-review experience served as evidence of his authority in the field. However, we even looked further into his credentials to build our petition packet. We were able to find details of his publishing record and citation count as well.

His publications have been cited by researchers around 281 times according to Google Scholar coming from independent and leading researchers from well-regarded institutions and organizations around the world, indicating the major significance of his work. This places our client in the top 1% of most highly cited authors publishing on topics in power electronics, renewable energy, and electrical engineering over the past 12 years according to Microsoft Academic. Furthermore, he holds an extensively documented record of authorship in his field of endeavor. As evidence of this research success, his work has resulted in 30 peer-reviewed scientific articles and 1 published patent, making it clear that his work is also considered to be among the best in the field.

Experts in the field have also attested to the importance of our client’s published body of work. The client has gathered advisory opinions from four dependent and independent experts out of which one of the independent experts had the following to say about him:

“In sum, [client’s] work in renewable energy and efficient use of power is important to the ongoing clean energy revolution. As fossil fuels lead to air pollution and other such issues, it is important that the [client’s] work is utilized to improve energy usage on a large scale. [Client’s] collective achievements in the field, from his original research to his peer review and publication records, further prove the extent of his expertise. Thus, [client] is truly a cutting-edge electrical engineering researcher deserving of a permanent position in the U.S. research community.”

As confirmed by the above evidence, our client is one of the few leading renewable energy and power electronics experts in his field and has achieved a consistent and notable record of success and influence in these areas of study.

Moreover, his work has received funding for education and workforce development, further validating the broad significance of his efforts. Our client’s work has thus been majorly significant, and his achievements are of the utmost importance due to their direct applicability in global efforts to address the increased utilization of renewable energy sources and technologies.

Consequently, his impressive background, strong record of past achievements, recognition of expertise by journals seeking his services to review manuscripts, and unique knowledge relevant to his current and future work indicate not only that he qualifies as an alien of extraordinary ability but also that his entry will substantially benefit prospectively the United States. We were thus very happy to know the positive response in his favor from the adjudicating judge in a short period of 3 months, 16 days, and are grateful to him for his continued trust in us. We wish him the very best in his life.
