Case Summary:

Another exceptional client that Chen Immigration Law Associates had the pleasure of working with is a research scientist from Pakistan with a specialization in vaccinology and epidemiology. His research specifically focuses on the study and development of effective and economical vaccines for a variety of infectious diseases including, but not limited to, enteric diseases that are prevalent in developing countries. This client wished to continue his research in Vaccinology and Epidemiology—a matter of critical importance to the maintenance of health, safety, and economy of our nation’s healthcare, government and industry. We at Chen Immigration Law Associates demonstrated that his continued employment in the field would not only benefit those in his field, but the citizens of the United States at large. To achieve success in this case, we submitted extensive documentation proving our client’s highly significant contributions to the field of vaccinology and epidemiology, including 17 peer reviewed articles, which garnered hundreds of citations by international scientists and researchers. This is a stellar record compared to that of his peers in the fields of vaccinology and epidemiology. Of his accomplishments, one of the independent recommenders remarked: “[His] current work is among his most ambitious and exciting. Working in league with the Global Alliance for Vaccines and Immunization (GAVI), an organization launched in 2000 to fund vaccines for children in the world’s 70 poorest countries, Dr. X and his colleagues are producing an investment case and advocacy strategy intended to pave the way for the introduction of Vi vaccine in typhoid-endemic developing countries.” Through extensive documentation, we at Chen Immigration Law Associates successfully argued that our client will serve the national interest to a significantly greater degree than others with similar education and experience. His NIW application was approved in 3 ½ months.
