Client’s Testimonial:

"Thank you so much for helping me throughout this process."

On July 20^th, 2026, we received another EB-2 NIW (National Interest Waiver) approval for a Graduate Student Research Assistant in the Field of Nutritional Epidemiology (Approval Notice).

General Field: Nutritional Epidemiology

Position at the Time of Case Filing: Graduate Student Research Assistant

Country of Origin: Nepal

State of Residence at the Time of Filing: Michigan

Approval Notice Date: July 20^th, 2026

Processing Time: 1 month, 28 days (Premium Processing Requested)

Case Summary:

North America Immigration Law Group (NAILG) represented a nutritional epidemiology researcher from Nepal whose work focuses on the relationship between environmental exposure, epigenetic regulation, maternal-child health, and nutrition-related disease prevention.

The client held an M.S. in nutrition and dietetics and had built specialized expertise in maternal and child nutrition, environmental exposure, food security, malnutrition, dietary interventions, and nutritional epidemiology. The client’s proposed endeavor focused on advancing research at the intersection of nutrition, environmental health, and disease prevention, with the goal of improving public health outcomes and informing evidence-based strategies for maternal and child health.

The petition documented a strong record of research achievement:

38 peer-reviewed journal articles, including 7 first-authored and 3 co-first-authored articles

1 first-authored conference abstract and 1 first-authored book chapter

3,775 citations

At least 36 completed peer reviews for authoritative journals

1 recommendation letter from an expert in the field, who provided a detailed assessment of the client’s research contributions, emphasizing both the scientific rigor and the practical public health implications of the work. The expert noted:

"Given the benefits that [Client’s] research presents to the US and nutritional epidemiology research as a whole, it is essential that he be retained in the nation."

NAILG also highlighted the extensive reliance on the client’s findings by independent researchers. Subsequent studies used the client’s work to support investigations involving various aspects of public health, nutrition, and disease prevention. This evidence demonstrated that the client’s research had influenced how other researchers approach maternal-child nutrition, environmental health, and disease prevention.

This approval reflected the successful presentation of a nutritional epidemiology case grounded in strong publication impact, substantial citation influence, peer review and editorial service, independent reliance, and a proposed endeavor aimed at improving maternal-child health, environmental nutrition, and evidence-based public health guidance in the United States.
