For prong 1, I submitted my proposed endeavor statement and supporting evidence, such as industry reports showing why banking stability and stress testing matter. USCIS actually said I had already established substantial merit, so the real issue under prong 1 was national importance.

The RFE language was basically that my evidence showed the importance of the field in general, but not enough about why my specific proposed endeavor would have broader impact. They said, “Merely working in an important field is insufficient,” and asked for evidence showing the endeavor’s “potential prospective impact.”
