This is an AAO appeal decision — a case denied once and appealed. It shows how the framework is applied; it is not the filing population.
The Petitioner, a chemistry professor, proposed to continue research developing and optimizing nanostructured materials to remove contaminants, microplastics, and radionuclides from water, improving water treatment, desalinization, and renewable energy applications.

Prong 3 — balance of factorsestablished
“we conclude that he offers contributions of such value that, on balance, they would benefit the United States even assuming that other qualified U.S. workers are available.”

What this case teaches
Analyst reading of the decision text.
AAO found petitioner's water-contaminant-removal research tied to national clean water initiatives, corroborated by citation impact and expert letters, satisfying all three Dhanasar prongs.
Link a specific technical research plan to concrete government policy priorities and corroborate impact with independent citation/expert evidence across all three prongs.
