Case Summary:

At North America Immigration Law Group, we are excited to share another NIW (National Interest Waiver) success, this time for an expert, also an M.Eng. holder in civil engineering from Nigeria, whose petition was approved in 6 months and 17 days under Premium Processing, despite receiving a Request for Evidence (RFE).

Our client is an accomplished expert in material engineering, with a research focus on developing sustainable concrete technologies using advanced material characterization, concrete mix design, and finite element analysis. His proposed endeavor addresses critical national concerns such as reducing CO₂ emissions from the construction industry and improving the resilience of infrastructure systems across the U.S.

At the time of filing, the client was continuing his research efforts in the U.S. and planning to join a material science-focused company, where he would contribute to developing next-generation cementitious binders and concrete structures using recycled industrial by-products.

To support his NIW petition, we emphasized:

Publications and Citations: He has authored 11 peer-reviewed publications, including 8 journal articles, 1 conference paper, 1 preprint, and 1 accepted manuscript, with 21 citations from global researchers who have applied his work in sustainability, concrete performance, and soil stabilization.

Peer Review Contributions: He has completed at least 20 peer reviews and serves on multiple editorial and advisory boards for top journals and conferences in civil engineering.

Significance and Impact: His work has influenced researchers across four continents and directly supports U.S. goals in infrastructure modernization, carbon reduction, and construction innovation, recognized as part of “critical and emerging technologies” by national agencies.

Despite the RFE, our team provided strong evidence of the national importance and merit of his endeavor. We’re proud to support his continued efforts in building a greener and more resilient America.
