Case Summary:

At Chen Immigration Law Associates, we received another NIW approval notice for a client in the field of chemical physics. This client is a postdoctoral research associate focusing on the highly specialized areas of molecular spectroscopy of reactive intermediates in the atmosphere, and the molecular dynamics of reactive intermediates and energetic materials. In order to ensure the success of this case, we submitted extensive documentation of the client’s highly significant contributions to the field of chemical physics. Our client’s work has resulted in at least 10 peer-reviewed scientific articles published in leading journals, and twenty-one presentations at national and international conferences and seminars. Furthermore, his work has been cited 45 times by independent and leading researchers from prestigious institutions and organizations around the world, indicating the major significance of his work. Additionally, our firm drafted and submitted several recommendation letters from experts in our client’s shared field. One of the independent recommenders, an assistant professor from Japan, stated, “[T]he achievements by [the Petitioner] so far are exceptional, but more than that, his ability and talent to do this type of scientific investigation is not common. In my expert opinion, I believe that it would be in the best interest of the United States of America to not only accept [the Petitioner’s] petition, but encourage his work for I am certain that mind like [the Petitioner] has just begun to impact the scientific world.” With the strong petition letter and recommendation letters we prepared, his NIW case was approved in less than 5 months.
