Case Summary:

In this case, the client that we had the opportunity to work with was an interventional nephrologist from India. In addition, his specialized research has focused on elucidating metabolic abnormalities and anemia in kidney disease, as well as the multiple myeloma (blood cancer) associated with kidney disease and post-operation complications of kidney transplantation. His work had resulted in at least 19 peer-reviewed scientific articles and numerous presentations at national and international conferences; at the time that his case was filed, his publications had been cited at least 54 times by independent and leading researchers from prestigious institutions and organizations around the world, indicating the major significance of his work. He had also reviewed 16 manuscripts for 5 distinctive, internationally-circulated journals. His superior level of expertise was confirmed in the following quote from an independent recommender, “[Client’s] finding has impacted the way HIV patients are able to receive kidney transplants without automatically facing biased selection. [Client’s] research has resulted in more and more patients with HIV receiving vital kidney transplants. […] His work ethic, ingenuity, passion for his patients is truly an asset to American society.” It was our goal to prove that our client qualified for classification as an Alien of Extraordinary Ability given that he sought to remain in the United States to continue work in the area of Nephrology, and that his continued research would substantially and prospectively benefit the United States. With the proof and documentation that we provided, his case was approved in 27 days.
