General Field: Mechanical Engineering

Position at the Time of Case Filing: Research Engineer

State of Residence at the Time of Filing: Wisconsin

Approval Notice Date: March 31st, 2020

Processing Time: 5 months, 7 days

Case Summary:

The field of mechanical engineering has seen much progress since our client, a research engineer from Greece, chose to dedicate his career to it. Thanks to our expertise and over 16,000 I-140 approvals we have obtained throughout the years, we quickly determined the best direction our client’s NIW petition should take. The documentary evidence we submitted proved that our client is working at the absolute forefront of mechanical engineering and that his leadership is facilitating advancement in many different areas in the field. His NIW petition was approved in just 5 months and 7 days.

Over the years, he has amassed various achievements such as an incredible number of citation count and publication record. At the time of filing, these numbers stood at 79 citations and 12 peer-reviewed journal articles and conference papers (6 of them first-authored). Moreover, these papers have been published in the top journals in the field of mechanical engineering, which reflects his peers’ recognition of the value of his research. He has also conducted 24 reviews for multiple highly acclaimed journals. This incredible number of citations demonstrates the tremendous influence his work has had on the field, and that he is an influential researcher whose opinions are highly respected by his peers.

After we were retained, our team built a comprehensive and personalized petition that focused on his unique skills and strengths. As an expert in the field of mechanical engineering, our client’s specialized research has focused on developing high-efficiency internal combustion engines that produce low emissions while using conventional and alternative fuels, which are critical components of the modern and future transportation as well as the power generation landscape. We made it our goal to convince the USCIS that his work is important to the US because it has significantly promoted understanding of the underlying processes of these engines and facilitated the optimization of their design.

We further fortified our client’s NIW petition by incorporating recommendation letters signed by other experts in the field. These letters served as subjective evidence that our client’s work has produced major breakthroughs in the field.This is what one of his recommenders noted in his testimonials: “[Client’s] progress in our field directly results in technology that slows the advancement of global warming, making continued support for his research a top priority.”

We are pleased that we convinced the USCIS of the international influence and widespread implementation of our client’s work. We congratulate our client for securing the NIW petition and green card approval, and we wish him the very best as he embarks on his exciting new journey as an American permanent resident.
