Another exceptional client that North America Immigration Law Group – had the pleasure of working with was an Assistant Professor originally from China working in the field of Statistics. The client holds both a Master’s degree in Mathematical Statistics from China and a Ph.D. degree in Statistics from the United States (completed one month before filing the case). More specifically, his work addressed choosing appropriate models, reducing the impact of measurement errors on data, and improving perameter estimation. We at North America Immigration Law Group – demonstrated that the client’s continued employment in the field would not only benefit those in the field of statistics, but the citizens of the United States at large by showing how the client’s research results have directly contributed to a host of fields and industries that rely on statistical analysis for the collection, analysis, interpretation, explanation, and presentation of data. In this way, we were able to demonstrate the wide-reaching impact of the client’s work, as well as demonstrate how this work is in the national interest. To achieve success in this case, we submitted extensive documentation proving our client’s highly significant contributions to the field of Statistics, including at least 9 peer-reviewed articles published in leading field journals and numerous conference presentations to national and international audiences. The client’s 9 publications had been cited at least 21 times at the time of case filing.  Of these accomplishments, one of the 7 recommenders remarked: “I am convinced that [Client’s] exceptional research work is just the beginning of ever more impressive successes he will achieve in the future using his extraordinary ability to integrate irregular data sets with statistical modeling methods. He has been and will continue to be an extraordinary mathematician, making original contributions vital to the United States’ national interests.” Through extensive documentation, we at North America Immigration Law Group – successfully argued that our client would serve the national interest to a significantly greater degree than others with similar education and experience. His NIW application was approved in just 27 days.
