Case Summary:

Here at Chen Immigration Law Associates, we recently received another EB1A approval for a visiting research professor working in the field of operations research through pioneering research in optimization models and algorithms. Our client has focused on the research and development of mathematical models and formulations to optimize large-scale industrial and government operations through standardization, novel data correcting and tolerance-based algorithmic techniques, as well as introduced a new wave of enumerative algorithms for solving resource allocation problems. His work has resulted in at least 5 textbooks and books, over 65 peer-reviewed articles, 51 conference publications, 31 chapters in books and manuals, and 3 monographs. In addition, our client’s publications have been cited at least 515 times by leading and independent researchers around the world. Our client’s expertise can also be seen in a quote by an independent recommender, “[The Petitioner] has summarized this book through his own work, having created additional models and algorithms that are sure to continue benefiting leading production companies in the United States, and thereby positively influencing the U.S. economy.” It was our goal to prove that this client qualifies for classification as an alien of extraordinary ability given that he seeks to remain in the United States to continue work in the area of extraordinary ability, and his continued research will substantially and prospectively benefit the United States.
