Success Story: Advancing High-Performance Computer Architecture: NIW Approval for a Computer Architecture Researcher
Client’s Testimonial:
"Thank you very much for all your support throughout my I-140 NIW petition process. It was also a pleasure for me to work with the Chen Immigration Team.”
On July 9th, 2026, we received another EB-2 NIW (National Interest Waiver) approval for a Senior Engineer in the Field of Computer Architecture (Approval Notice).
General Field: Computer Architecture
Position at the Time of Case Filing: Senior Engineer
Country of Origin: United Kingdom
Country of Residence at the Time of Filing: South Korea
Approval Notice Date: July 9th, 2026
Processing Time: 3 months (Premium Processing Upgrade Requested)
Case Summary:
We are pleased to share another National Interest Waiver (NIW) approval for a researcher in the field of computer architecture. The client earned a Ph.D. in electrical and computer engineering and sought classification under the NIW category based on research focused on improving high-performance computer architectures for artificial intelligence (AI), large-scale data analytics, and high-speed computing applications.
The client's work centers on developing high-performance computer architectures through system-level modeling, simulation, and hardware-aware optimization techniques. By reducing data movement bottlenecks between processors and memory systems, the client's research aims to improve the efficiency, scalability, and energy performance of AI systems and other data-intensive computing applications. In our petition, we demonstrated that this research addresses nationally important challenges, including the growing computational demands of AI and the need for more energy-efficient computing infrastructure, making it well aligned with the National Interest Waiver framework.
To establish that the client was well positioned to advance this important work, we highlighted both the quality and influence of the client's scholarly contributions. At the time of filing, the client had authored 2 peer-reviewed journal articles, 3 peer-reviewed conference articles (including one first-authored publication), and 2 granted patents, while the published research had been cited 88 times by other researchers. Rather than presenting these numbers alone, we explained why they matter in the field of computer architecture. Because leading conferences in computer science are widely recognized as premier publication venues, the client's publication record reflected meaningful scholarly achievement. We also emphasized that one of the client's publications ranked among the top 10% most-cited papers for its publication year, demonstrating that other researchers had independently relied on the client's findings when advancing their own work.
Another important aspect of the petition involved demonstrating that the client's research had already influenced the broader scientific community. We discussed examples of independent researchers incorporating the client's work into studies involving AI acceleration, memory systems, and computer architecture, showing that the client's contributions had practical value beyond the original publications. This evidence helped illustrate that the client was not only producing research but also shaping ongoing developments in the field.
We also submitted three expert recommendation letters from established professionals in the field. These letters explained how the client's work contributes to advances in computer architecture and why continued research would benefit the United States. Combined with the independent evidence presented throughout the petition, these recommendations reinforced that the client possesses the expertise and record of success needed to continue advancing this nationally important area of research.
“It is therefore imperative that he be permitted to continue his research uninterrupted so that the United States may fully realize the technological and strategic value of his work.”
After reviewing the evidence, USCIS approved the client's I-140 National Interest Waiver petition, recognizing that the client is well positioned to continue advancing research that supports more efficient computing systems for AI and other data-intensive technologies while benefiting U.S. technological innovation.
