On September 18th, 2026, we received another EB-2 NIW (National Interest Waiver) approval for a Graduate Teaching Assistant in the Field of Materials Science (Approval Notice).
General Field: Materials Science
Position at the Time of Case Filing: Graduate Teaching Assistant
Country of Origin: Iran
State of Residence at the Time of Filing: Texas
Approval Notice Date: September 18th, 2026
Processing Time: 24 months, 29 days (Premium Processing Upgrade Requested)
Case Summary:
The client, who holds an M.S. in materials engineering, was approved under the EB-2 National Interest Waiver category for research focused on improving materials used in additive manufacturing. The client’s proposed endeavor centers on analyzing and optimizing the microstructural and mechanical properties of materials to support stronger, more durable components for critical aerospace and automotive applications.
At the time of filing, the client was conducting materials science research at a U.S.-based academic institution. The client’s work involved advanced characterization and mechanical testing methods used to study materials processed through additive manufacturing and related manufacturing techniques. The petition also explained that the client planned to continue work in a manufacturing engineering role or similar position aligned with this specialized research area.
The petition demonstrated that the client had developed a focused research portfolio at the intersection of materials science, additive manufacturing, laser-based processing, and mechanical performance analysis. The client’s contributions included work on optimizing laser welding parameters, studying microstructural changes in engineering materials, and developing thermal processing approaches intended to improve material strength, durability, and reliability.
The client established a focused scholarly profile, including:
- 5 peer-reviewed journal articles, including 2 first-authored journal articles
- 2 peer-reviewed conference papers, including 1 first-authored conference paper
- 78 citations to the client’s published work
While the client’s publication record was specialized in scope, the petition presented these outputs as meaningful contributions within materials science. The record showed that the client’s work had appeared in reputable venues and had been cited by other researchers studying laser welding, microstructure analysis, additive manufacturing, and material performance.
The petition framed the client’s proposed endeavor as nationally important because stronger and more durable materials are essential to industries where material reliability directly affects safety, performance, and innovation. In particular, the petition connected the client’s research to aerospace and automotive applications, where improved materials can support safer structures, more reliable components, and more efficient manufacturing practices.
The petition also emphasized that additive manufacturing continues to play an important role in producing complex and high-performance components. By improving the understanding of how manufacturing conditions affect microstructure and mechanical behavior, the client’s research supports broader efforts to develop materials that can withstand demanding operating environments.
To demonstrate the client’s significance, North America Immigration Law Group did not rely on publication and citation numbers alone. We placed the citation record in context by showing that one of the client’s papers ranked among the top 20% most-cited Materials Science articles for its publication year. This helped demonstrate that the client’s work had received meaningful attention within the field.
We also highlighted examples showing that independent researchers had relied on the client’s findings in later studies involving laser welding, hot cracking reduction, material processing, microstructure evaluation, and mechanical performance. These examples helped show that the client’s work had practical value beyond publication and had contributed to how other researchers approach the development and evaluation of stronger engineering materials.
Overall, USCIS approved the client’s I-140 NIW petition after a premium processing upgrade. This approval reflected the successful presentation of a materials science case grounded in additive manufacturing research, scholarly publication, independent citation reliance, and the national importance of developing stronger and more durable materials for critical U.S. industries.
