(EB2-NIW) – Public Health Researcher specializing in indoor air quality; approved in 16 days.

When Victor E., a public health researcher specializing in indoor air quality, approached HoatPen, his goal was to secure an EB2-NIW (National Interest Waiver) based on his impactful contributions to environmental health research. With 15 peer-reviewed publications and over 50 citations, Victor had already established a solid academic record — but he needed to translate those achievements into a compelling case that clearly met the USCIS Dhanasar framework requirements.

Our team began by performing a deep analysis of Victor’s body of work to align it with the three Dhanasar prongs. For the first prong — substantial merit and national importance — we emphasized how his studies on indoor air pollutants, ventilation systems, and respiratory health outcomes contribute to national public health priorities, particularly in reducing environmental exposure-related diseases. We referenced the broader relevance of his work to national goals set by the CDC and EPA, demonstrating its tangible impact on improving indoor air standards and community health.

Under the second prong — well-positioned to advance the proposed endeavor — we presented a detailed narrative supported by evidence of Victor’s leadership in ongoing research projects, collaborative studies with international partners, and his strong publication record. Letters from peers and institutional collaborators reinforced his credibility and the continued relevance of his research within the U.S. scientific community.

For the third prong — benefit to the United States outweighing the need for labor certification — our argument focused on how Victor’s independent research efforts and innovative methodologies serve the U.S. public interest by addressing environmental health disparities and promoting preventive care strategies.

Through a balanced mix of technical documentation and persuasive writing, we built a petition that was both legally sound and scientifically compelling. The result? USCIS approved Victor’s EB2-NIW petition in just 16 days — a clear reflection of a strong, evidence-backed case developed with precision, structure, and purpose.

At HoatPen, we’re proud to have helped Victor turn his public health research into an immigration success story that truly stands out.
