Case Summary:

We are pleased to share the EB-2 NIW approval of a Principal Eng Test Engineering from Bangladesh. At the time of filing, the client was working in the United States, developing advanced optimization algorithms, statistical modeling, and machine learning techniques for semiconductor testing and manufacturing. His work improves production efficiency, precision, and reliability in technologies such as 5G/6G communications, autonomous systems, and national defense applications. With a strong record of publications, citations, and industry-supported research, he presented a persuasive case for NIW approval.

Research with Substantial Merit and National Importance

The client’s proposed endeavor centers on integrating machine learning and optimization strategies to enhance semiconductor testing and fabrication. His studies address inefficiencies in high-frequency chip production and introduce methods that reduce cost, time, and error in semiconductor manufacturing. By contributing to more efficient production pipelines, his work supports U.S. competitiveness in 5G/6G communications, automation, and defense technology.

His earlier research developed optimization frameworks for massively parallel electron-beam systems, enabling faster and more precise chip patterning, and adaptive algorithms that improve energy stability in smart grids. These accomplishments demonstrate both scientific depth and practical significance, aligning with national goals for semiconductor innovation and infrastructure resilience.

Academic and Professional Record

The client holds a Ph.D. in electrical engineering and has authored six peer-reviewed journal articles and one conference paper, including four first-authored works in reputable outlets such as Journal of Vacuum Science & Technology B and Digital Communications and Networks. His work has been cited 23 times by independent researchers and applied in areas spanning chip manufacturing and smart energy systems.

In addition, he received research endorsement and funding support from Samsung Electronics, an acknowledgment typically reserved for projects with exceptional technological and societal relevance. This recognition underscores the real-world value of his contributions.

Expert Recognition

Independent experts commended the originality and national importance of his work.

One recommender noted:

“To summarize, it is clear that [client] stands at the top of his field, given his achievements in improving semiconductor manufacturing speed and precision, reducing energy demand during peak hours, and creating adaptive algorithms that respond effectively to real-time conditions. Ensuring the continuation of [client]’s work is thus deeply important to both electrical engineering research and to the nation.”

This endorsement highlights the innovation, relevance, and lasting value of his contributions.

NIW Approval and Outlook

The I-140 NIW petition was filed on July 21, 2025, and approved on September 18, 2025, under premium processing. USCIS recognized his scholarly output, citation impact, and nationally significant research as sufficient to satisfy the NIW criteria.

With NAILG’s support, the client secured NIW approval and is now advancing semiconductor optimization research in the United States. His ongoing work continues to strengthen U.S. manufacturing capacity, improve production efficiency, and reinforce America’s leadership in critical technology sectors.
