“I am very pleased to hear the good news of my I-140 approval. The fact that it was approved before the 45 business days timeline and without an RFE makes the news even sweeter :)”

Case Summary:      

We at NAILG are pleased to share the approval of an EB-2 NIW (National Interest Waiver) petition for a hospitalist physician from Cameroon, currently engaged in groundbreaking research in the field of epidemiology. The petition was filed with premium processing on July 16, 2025, and approved just one month later, on August 16, 2025.

Case Background

The client approached NAILG with a vision of continuing his dual clinical and research work in the United States, focusing on cardiometabolic diseases and the health consequences of e-cigarette use. At the time of filing, he was employed as a hospitalist physician, while actively contributing to clinical and public health research initiatives.

Research and Impact

NAILG highlighted that the client’s work addresses urgent public health priorities such as:

• Advancing strategies for disease prevention and early diagnosis in cardiometabolic conditions.
• Developing tools for more precise risk stratification and improved therapeutic outcomes.
• Investigating the long-term health risks associated with e-cigarette use, including its impact on bone health.

His research has led to eight peer-reviewed journal articles, three of which he authored as first author, and his findings have accumulated 198 citations in scholarly literature. In addition, he has contributed as a peer reviewer for respected journals, further reinforcing his leadership role in the field. Several of his papers are ranked among the most highly cited in clinical medicine for their publication years, demonstrating both originality and influence.

Expert Endorsements

Letters of recommendation submitted in support of the case underscored his contributions to U.S. public health. One expert summarized his impact by stating:

“[Client’s] research offers substantial benefits to U.S. public health by enhancing the understanding and management of chronic metabolic diseases. His work directly informs preventive care and reduces disparities, particularly among African American populations.”

Another recommender highlighted his influential study on e-cigarettes, noting that it “provides essential evidence that challenges the perception of e-cigarettes as a safe alternative, ensuring healthcare professionals and policymakers are better equipped to protect vulnerable populations.”

Recognition and Support

The petition also emphasized that the client’s research has been funded by major U.S. health institutes, including the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), the National Institute on Aging (NIA), and the **National Heart, Lung, and Blood Institute (NHLBI). Such funding underscores the national importance of his work and validates its potential to improve population health outcomes.

NIW Approval and Outlook

Thanks to NAILG’s tailored legal strategy and careful presentation of evidence, USCIS recognized the substantial merit and national importance of the client’s research, as well as his unique qualifications to advance it. With his NIW approval secured, he is now positioned to expand his epidemiological investigations and continue contributing to evidence-based healthcare that benefits both the U.S. and the global community.

This approval reinforces NAILG’s commitment to supporting talented professionals whose expertise in medicine and public health aligns with critical national interests.
