Case Summary:

North America Immigration Law Group (NAILG) has successfully attained over 16,000 I-140 immigration petitions. Our sterling reputation as a law firm that offers customized I-140 petitions and unprecedented insight into how the USCIS adjudicates cases are reasons why clients from all over the world seek our help for their green cards. In this case, a postdoctoral research associate from Vietnam hired us to help him with the first step in the green card process: filing an I-140 petition under the EB-2 NIW (National Interest Waiver) category.

Based on his research background and professional achievements, we determined that we would focus on his publication record and impressive citation count. At the time of filing, these numbers stood at 33 peer-reviewed journal articles and 4,165 citations, thereby demonstrating that these publications are widely recognized and relied upon in the field of experimental particle physics. His specialized research focuses on experimental neutrino oscillations and neutrino interactions. We emphasized that his research in this field is of great importance because it advances understanding of neutrino properties, which itself has important implications for scientific inquiry into matter and antimatter, the origins of the universe, and other vital topics. His research therefore, yields innumerable benefits for the field and indeed the entire endeavor of scientific inquiry.

Further corroboration of the significance of his research was provided through 4 letters of recommendation volunteered by distinguished experts and researchers. One of these recommenders stated that: “The United States, as the global leader in technological innovation in almost all areas of study, is particularly well-situated to take advantage of the breakthrough technologies that are enabled by advances in neutrino physics. [Client] is an unquestioned leader in neutrino physics and is therefore facilitating a wide range of discoveries in multiple fields through his important work.”

We congratulate our client on overcoming this great hurdle, and we wish him the best as he continues to carry out impactful research in the United States. Now that he has received the NIW approval, he is only one step away from obtaining the green card. We thank our client for trusting our services and choosing us to represent his I-140 and I-485 cases.
