General Field: Hepatology

Case Summary:

An Indian fellow hired North America Immigration Law Group ( to build a customized O1-A (Individuals with Extraordinary Ability or Achievement) petition for her. To qualify for an O-1 visa, the beneficiary must demonstrate extraordinary ability by sustained national or international acclaim and must be temporarily in the US to continue work in the area of extraordinary ability. It took USCIS merely 14 days to adjudicate our client’s petition thanks to Premium Processing (PP).

In order to prove that our client merited a granting of the O-1 visa for extraordinary ability, our team carefully reviewed her credentials and claimed the following criteria – original contributions of major significance in the field, authorship, and judge of the other’s work.

Our client’s work on liver disease has significantly contributed to medical research and public health. Her research addresses some of our nation’s most pressing issues in understanding the molecular mechanisms underlying the pathogenesis of hepatocellular carcinoma (liver cancer). At the time of filing, she has published 20 peer-reviewed scientific articles which accumulated 403 citations from leading researchers around the world. In addition, she has also served as peer-reviewer for highly acclaimed journals and conducted 12 reviews. As peer review process ensures the integrity and quality of research in the field, our client certainly provides insights and support to her peers.

To further strengthen her case, we also advised our client to reach out to multiple well-known researchers and ask for recommendation letters. In one of the letters, a convincing statement indicated: “In fact, [client’s] provision of both basic and translational research, demonstrable influence, and recognition by other expert pathologists makes it clear that she is operating at the leading-edge of her field. Considering the dire need for both a better understanding of liver disease and more effective treatment options, [client’s] research is critical to improving public health in the United States.”

With prudence, we leveraged our client’s strengths and provided effective evidence to help our client receive her O1-A petition approval in 14 days after case filing. Our team possesses vast experience in employment-based visa petitions, and thus aided us with efficient legal strategies for this O-1A approval. We congratulate her for the O-1A approval and wish her the best as she continues to advance in the field of hepatology in the United States.
