Success Story: O-1A Approved Despite RFE! Indian Hospitalist Achieves Immigration Success

On September 24th, 2025, we received another O1-A (Individuals with Extraordinary Ability or Achievement) approval for a Hospitalist in the Field of Internal Medicine (Approval Notice).


General Field: Internal Medicine

Position at the Time of Case Filing: Hospitalist

Country of Origin: India

State of Residence at the Time of Filing: New Mexico

Approval Notice Date: September 24th, 2025

Processing Time: 3 months, 12 days (Premium Processing Requested)


 Case Summary:  

“Given the complexity of rare and debilitating conditions like CSVT, it is clear that further advances in targeted treatment are needed. As [Client] has produced highly valuable research in this regard, there is an ongoing demand for her particular expertise in internal medicine.”

The above statement, taken from one of the four recommendation letters submitted as part of the I-129 O-1A petition, reflects the high level of recognition earned by a physician-scientist with an M.B.B.S. degree and extensive contributions to internal medicine. Our team carefully structured the petition to emphasize both the originality of the client’s research and its broader importance to U.S. healthcare priorities.

The client’s specialized research has focused on a wide range of complex, multi-system conditions, with a particular emphasis on neurological diseases. This work addresses some of the nation’s most pressing challenges in understanding neurovascular and neuromuscular disorders, while also targeting gaps in medical education and clinical workflows. The research spans critical applications such as advanced imaging and diagnostics, personalized medicine, immunotherapy, and resident training, all of which enhance patient care and outcomes.

To underscore her strong record of achievement, we highlighted an extensive body of scholarly work: 20 peer-reviewed scientific articles, 14 abstracts, and 3 book chapters. Collectively, her research has been cited 509 times, including high-impact papers such as a comprehensive review of cerebral venous thrombosis that has received over 200 citations and ranks among the top 1% most cited articles in its field. This evidence demonstrates that her work has significantly influenced clinical practice and ongoing research globally.

The client’s role as a peer reviewer for leading journals further demonstrated her standing as a recognized expert. She has completed at least 39 reviews to date—an important responsibility reserved for those regarded as leaders in their field.

Despite receiving a Request for Evidence (RFE), the client’s O-1A petition was ultimately approved under Premium Processing, affirming her qualifications as an individual of extraordinary ability in internal medicine. We are proud to have supported this accomplished physician-researcher and wish her continued success as she advances research and care practices that improve patient outcomes worldwide.
