The Petitioner, a scientist pursuing a Ph.D., proposed to develop advanced sensor technologies and data-driven guidance to monitor heavy metal levels in water and commercial products, though he later revised this to developing miniature electrochemical biosensors for early detection of neurological diseases like Alzheimer's and Parkinson's.

Prong 1 — national importancenot established · dispositive

“Here, the nature of the Petitioner's proposed endeavor is unclear.”

“The Petitioner's response significantly departed from the proposed endeavor he indicated in his initial filing.”

“The Petitioner's materially significant transformation rendered his proposed endeavor ill-defined and amorphous.”

“The Dhanasar framework cannot be applied to two dueling proposed endeavors.”

“Therefore, it is not possible to determine the substantial merit and national importance of an endeavor when a Petitioner cannot consistently articulate the nature of the endeavor.”

AAO decision text

How the evidence was treated

• recommendation letter · ignored
• other · discounted

  “The Petitioner's RFE response constituted a materially different proposed endeavor, with a different purpose and proposed location”

  AAO decision text

Where this case turned

• Endeavor too vague · p1 — described as a job role, not a defined undertaking
• Material change of endeavor · p1 — the endeavor described on appeal is not the one filed

Notable

The AAO's dismissal turned entirely on a material-change-of-endeavor theory (citing Matter of Izzumi/Katigbak) rather than a standard national-importance merits failure: the Petitioner substantially revised the substance and location of his proposed endeavor in his RFE response, which the AAO held rendered the endeavor 'ill-defined and amorphous' and impossible to analyze under Dhanasar prong one. Prongs two and three were expressly reserved.
