A doctoral student in mechanical engineering proposed work on HVAC system efficiency improvement. The AAO dismissed the appeal, holding that the applicant failed to demonstrate national importance of the specific endeavor; the general importance of energy efficiency in buildings was insufficient without showing broader field impact.

A field engineer and X-ray fluorescence analyst sought a national interest waiver for EB-2 classification. The AAO held that while the proposed research endeavor on petroleum engineering and methane emissions demonstrates substantial merit, it lacks national importance under Dhanasar's first prong, and did not address the remaining prongs.

Engineer with 20 years water systems experience seeks NIW to expand his consulting company offering engineering services for water infrastructure. AAO dismissed appeal because proposed endeavor lacks national importance despite working in critical field; benefits do not extend beyond his company.

Computer scientist with advanced degree sought EB-2 NIW for data warehouse and machine learning research. AAO held proposed research lacked sufficient detail and documentation to demonstrate national importance beyond employer; relied on petitioner's own statements without corroborating evidence.
