A mechanical engineer with Ph.D. equivalent seeks EB-2 national interest waiver for research improving fault diagnosis and predictive maintenance in heavy machinery. The AAO dismissed because the petitioner demonstrated substantial merit but failed to establish national importance, submitting only general background articles without sufficient evidence of prospective national-level impact.
0 of 3 criteria metRead → - EB-2 NIWMechanical and aerospace engineering2026Dismissed
Mining engineer sought EB-2 with national interest waiver to improve domestic mining of critical minerals through block-cave mining expertise. AAO dismissed, finding the proposed endeavor lacked national importance because evidence only demonstrated importance of the critical minerals field itself and benefits to individual companies, not broader implications for the mining industry.
0 of 3 criteria metRead → - EB-2 NIWMechanical and aerospace engineering2026Dismissed
Materials engineer self-petitioner sought NIW for EB-2 advanced degree. AAO affirmed dismissal because petitioner failed to establish national importance of proposed solar industry corrosion management solution; industry-wide statistics do not prove specific endeavor impact. Petitioner also not shown well positioned to advance endeavor.
0 of 3 criteria metRead → - EB-2 NIWMechanical and aerospace engineeringDec 2025Dismissed
An aerospace quality engineer sought NIW claiming his work on quality standards and mentoring would benefit the aviation industry. The AAO dismissed the appeal because he failed to establish that his specific proposed endeavor had national importance beyond typical occupational duties.
0 of 3 criteria metRead → - EB-2 NIWMechanical and aerospace engineeringDec 2025Dismissed
Research associate with master's in mechanical engineering sought EB-2 NIW to continue carbon capture and sustainable aviation fuel research. First prong met. AAO affirmed second prong failure: education strong but lacks Ph.D., plan insufficient, no documented role in obtaining funding; appeal dismissed.
1 of 3 criteria metRead → - EB-2 NIWMechanical and aerospace engineeringDec 2025Dismissed
Automotive engineer sought EB-2 NIW to develop Advanced Driver Assistance Systems. AAO clarified Dhanasar does not require percentage thresholds but affirmed petitioner failed to show broad technological or public safety implications at national importance level. Motions to reopen and reconsider dismissed.
0 of 3 criteria metRead → - EB-2 NIWMechanical and aerospace engineeringDec 2025Dismissed
An aircraft maintenance technician sought NIW for EB-2. The AAO found the proposed endeavor met the first Dhanasar prong on national importance but dismissed for failing the second prong. The petitioner lacked documented evidence of company existence, adequate funding, and a credible team to advance the proposed business.
1 of 3 criteria metRead → - EB-1AMechanical and aerospace engineeringNov 2025Dismissed
A post-doctoral researcher in engineering mechanics sought EB-1A classification. The AAO dismissed the appeal, finding the petitioner met only one of three claimed criteria and failed to demonstrate that his original contributions had major significance, falling short of the three-criterion threshold.
1 of 11 criteria metRead → - EB-2 NIWMechanical and aerospace engineeringNov 2025Dismissed
A mechanical engineering researcher with an advanced degree sought EB-2 national interest waiver. AAO dismissed the appeal, finding she was not well-positioned to advance her proposed sustainable energy research endeavor, and declining to reach the first and third prongs.
0 of 3 criteria metRead → - EB-2 NIWMechanical and aerospace engineeringNov 2025Dismissed
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.
0 of 3 criteria metRead → - EB-1AMechanical and aerospace engineeringNov 2025Dismissed
An oil and gas mechanical engineer sought EB-1A extraordinary ability classification. Although he satisfied three regulatory criteria (judging, scholarly articles, leading roles), the final merits analysis found he lacked sustained national or international acclaim and did not rank among the very top of his field.
3 of 6 criteria metRead → - EB-2 NIWMechanical and aerospace engineeringNov 2025Dismissed
Project engineer seeks national interest waiver for EB-2 classification. Business plan proposed personalized training in project engineering with claims of reducing reliance on foreign contractors. AAO found endeavor substantially meritorious but lacked national importance because benefits were specific to employer rather than having broader implications for the field.
