Case Summary:

We are pleased to share the approval of both the EB-2 NIW (National Interest Waiver) and EB1A (Alien of Extraordinary Ability) petitions for a biostatistics expert specializing in time-to-event data analysis and advanced statistical methodologies for cancer research.

Publications: 8 peer-reviewed journal articles in selective, high-impact journals.
Citations: His work has been cited 220 times in scholarly research worldwide, with multiple papers ranking among the most highly cited in their category.
Peer Review: The client has conducted at least 20 reviews for respected journals, reflecting the recognition of his expertise in validating the work of other scientists.
Funding Support: His research has been supported by the National Institutes of Health (NIH), underlining the importance of his contributions to advancing healthcare.

Support from Experts in the Field:
The EB1A petition was further strengthened by four recommendation letters from distinguished experts, including independent scholars from top institutions. These letters praised his innovations in statistical modeling for oncology and emphasized that his work has shaped ongoing advances in cancer prognosis and clinical trial efficiency.

“His outstanding scientific investigations have major significance for guiding treatment regimens and the continued involvement of [Client] in scientific inquiry is necessary for advancing the fight against cancer. It is therefore important that he be allowed to continue his research in the United States.”

Well Positioned to Advance the Proposed Endeavor:
With a Ph.D. in biostatistics and a professional record bridging academia and the pharmaceutical industry, the client is uniquely equipped to continue pioneering work in medical statistics. His methodological advances are directly applicable to oncology research, drug development, and trial optimization, fields of clear national and global importance.

Approval and Outcome:
After securing NIW approval in 2023, the client also obtained EB1A approval in February 2025, despite the higher scrutiny applied to extraordinary ability cases. Both approvals reflect his standing as a recognized authority in biostatistics and his proven capacity to benefit the United States through research-driven advancements in cancer treatment and clinical trial methodology. NAILG is proud to have successfully represented this client and looks forward to his continued impact on improving healthcare outcomes.
