Case Summary:      

We are pleased to celebrate the successful approval of both the National Interest Waiver (NIW) and EB1A petitions for an accomplished expert in public health and health policy. The NIW petition was approved in May 2024, and the EB1A was granted in June 2025 following a robust response to a Request for Evidence (RFE). These outcomes affirm the petitioner’s standing as a nationally significant researcher advancing health equity and outcomes in the United States.

Advancing Population Health and Reducing Health Disparities
With a Ph.D. in health policy and management, the petitioner is internationally recognized for his research on health services, epidemiology, and social determinants of health. His work focuses on understanding disparities in healthcare access and outcomes, particularly in underserved communities, with a major emphasis on the prevalence, risk factors, and outcomes associated with intracerebral hemorrhage (ICH) in the U.S. population.

Through his current research role in the United States, he continues to contribute to studies that inform equitable health policies and system improvements.

Demonstrated Impact Across Publications and Peer Recognition
At the time of filing, the petitioner had authored:

• 36 peer-reviewed journal articles,
• 39 conference abstracts,
• 1 preprint.

His publications have received 1,249 citations, according to Google Scholar, demonstrating the widespread application and influence of his findings in public health and clinical practice. He has also completed at least 50 peer reviews for respected journals, further reinforcing his stature as a trusted expert in the field.

Research Funding and National Relevance
The petitioner’s research has earned support from major institutions, including the Robert Wood Johnson Foundation (RWJF). His work directly informs national strategies to reduce the burden of stroke, improve population health outcomes, and address racial and socioeconomic disparities in healthcare delivery.

Strong Endorsements from Academic and Clinical Leaders
The petition was bolstered by four letters of recommendation, including multiple independent letters from experts in population health and epidemiology. These letters confirmed the petitioner’s key role in shaping current public health knowledge and his unique ability to drive forward evidence-based reforms.

“[Client] is a highly valuable public health researcher who must be allowed to continue his important work in the United States.”

Supporting National Priorities in Health Equity
The petitioner’s research aligns closely with U.S. public health priorities, particularly in the areas of stroke prevention, health disparities, and healthcare access. Through his scholarly excellence, practical contributions, and leadership in health policy, he has earned recognition as an individual of extraordinary ability whose work is clearly in the national interest.

We are honored to have supported his immigration journey and look forward to his continued impact on public health systems and communities across the country.
