Case Summary:

The client that we had the opportunity to represent in this case was a Postdoctoral Fellow from India working in the field of microbiology.  He had conducted his highly specialized research in the critical intersection between immunology and chromatin biology. This research addressed some of our nation’s most pressing issues in healthcare by contributing to the development of novel vaccination strategies and treatments for autoimmune diseases.  At the time of case filing, his work had resulted in at least in 6 peer-reviewed scientific articles.  These publications had accumulated at least 257 citations from leading researchers at renowned institutions around the world, serving as objective evidence of his sustained international acclaim, as well as his major influence and impact on his field.  Furthermore, he had reviewed at least 26 manuscripts for highly distinguished, internationally-circulated journals.  The benefits that his research brings to the United States’ scientific community and healthcare industry is summarized by the following quote from an independent recommender, “In the United States, research on cells in the immune system is helping to improve vaccinations and medical treatments to the benefit of US citizens. T cells are an integral component of the human immune system, protecting us from infectious diseases. Researchers studying T cells are a key part of an ongoing revolution towards improving healthcare quality in the U.S. [He] is part of an elite group of researchers who are using novel approaches to understand complex regulatory mechanisms that control T cell development and have confounded medical researchers for decades.” It was our aim to prove that our client qualified for classification as an Alien of Extraordinary Ability, as he sought to remain in the United States to continue working in the field of microbiology, and that his continued work would substantially and prospectively benefit the United States. With the documentation that we provided, his case was approved in just 25 days.
