Case Summary:

We are pleased to announce the EB-2 NIW (National Interest Waiver) approval of a wireless system applications engineer from China. At the time of filing, he was working in the United States, applying his expertise to advanced communication networks. He is best known for his contributions to signal processing and machine learning methods that strengthen the performance of wireless technologies such as cellular networks, Wi-Fi, and Bluetooth. His publications, growing citation record, and peer review service established a persuasive case for NIW approval.

Advancing National Priorities

At the core of the client’s research are algorithms that optimize wireless networks, enabling higher data rates, lower latency, and more reliable connectivity. These innovations are essential to the expansion of the Internet of Things (IoT) and the next generation of communication infrastructures, including 5G ecosystems.

The significance of his work lies in addressing national challenges. Reliable broadband access is a critical U.S. priority, with billions invested to expand digital infrastructure. His innovations provide solutions that enhance security, accessibility, and efficiency in communications technology, directly supporting these efforts and aligning with recognized national needs.

Scholarly Impact

The client holds a Ph.D. in electrical engineering and has authored a range of peer-reviewed work: one first-authored journal article, two first-authored conference papers, one abstract, and a book chapter. Together, his studies have attracted 46 independent citations, with one paper ranked among the top 20 percent most cited in engineering for its publication year.

He has also been called upon to evaluate the work of peers, completing at least seven reviews for respected journals and conferences, including ACM Computing Surveys and IEEE Transactions on Intelligent Transportation Systems. Such invitations are extended only to trusted experts, underscoring his credibility in the field.

Expert Endorsements

Independent recommenders echoed the national importance of his contributions.

One expert explained:

“[Client] stands out not only for his role in advancing academic research of electrical engineering but also for the practical applications of his work that directly support the interests of the United States.”

Such recognition confirmed that his work has both originality and practical impact, marking him as a researcher of distinction.

NIW Approval and Outlook

The I-140 NIW petition was filed on January 2, 2024. USCIS issued a Request for Evidence (RFE) on June 23, 2025, which was met with additional evidence highlighting his scholarly influence and the national significance of his work. The case was approved on September 16, 2025.

With NAILG’s guidance, the client successfully secured NIW approval despite the RFE challenge. He is now positioned to continue advancing next-generation wireless communication systems in the United States, supporting the expansion of IoT, 5G, and beyond while reinforcing U.S. leadership in communication technology.
