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 sought to conduct research developing new techniques to extract diagnostic information from medical images, including AI-driven ultrasound imaging systems for lung disease and stroke assessment.

AAO reversed the Director on all three Dhanasar prongs, finding the Director erred in concluding national importance, well-positioning, and balance-of-benefit were not met; relies on USCIS Policy Manual F.5(D)(2) STEM PhD/critical-and-emerging-technology factor as a 'strong positive factor' supporting prong three.

What this case teaches
Analyst reading of the decision text.
AAO found national importance satisfied via documented broad, field-wide prospective impact of ultrasound diagnostic research (large federally/foundation-funded project, novel widely-used tools), reversing Director's contrary finding.
Support national importance with concrete evidence of large-scale funding, field-wide adoption of prior innovations, and multi-setting real-world deployment, not just personal credentials.
