Success Stories: Staff Engineer Secures NIW Approval After RFE for Semiconductor Yield-Enhancement Research
Client’s Testimonial:
“I am truly thankful for the approval of NIW in such a short period of time.”
On August 23rd, 2025, we received another EB-2 NIW (National Interest Waiver approval for a Staff Engineer in the field of Nanochemistry (Approval Notice).
General Field: Nanochemistry
Position at the Time of Case Filing: Staff Engineer
Country of Origin: South Korea
Country of Residence at the Time of Filing: South Korea
Approval Notice Date: August 23rd, 2025
Processing Time: 6 months, 26 days (Premium Processing Requested)
Case Summary:
We are pleased to share the success story of an EB-2 NIW (National Interest Waiver) approval. This approval was granted to a staff engineer from the Republic of Korea. The client’s research focuses on developing yield-enhancing methodologies in semiconductor chip fabrication to identify and address the root causes of yield detraction. At the time of filing, he had already established a strong record of research in semiconductor manufacturing and nanochemistry and had plans to continue advancing this work in the United States.
Research with Substantial Merit and National Importance
The client’s proposed endeavor involves advancing semiconductor manufacturing through the development of methodologies that improve yields in the fabrication of logic and memory products. By defining and solving problems that lead to defects, his work enhances the efficiency, reliability, and performance of semiconductor devices. This research is nationally important, as semiconductors are critical components in electronics, communications, defense systems, and consumer technologies. His work directly aligns with U.S. priorities in strengthening domestic manufacturing, ensuring supply chain resilience, and maintaining leadership in critical and emerging technologies.
Well Positioned to Advance the Proposed Endeavor
The client holds a Ph.D. in chemistry and has extensive experience in nanochemistry, supramolecular chemistry, and semiconductor process chemistry. His research achievements include 3 peer-reviewed journal articles (one first-authored), 1 abstract, and 1 granted patent. These works have appeared in leading journals such as Advanced Materials, Cancer Immunology Research, and Scientific Reports. His publications have been cited 130 times, with at least two articles ranked among the top 20 percent most cited in materials science for their years of publication.
In addition, the client has been invited to present his research at respected scientific institutions, further confirming his recognition within the field. His discoveries have been cited by independent researchers in cancer therapy, nanotechnology, and semiconductor-related studies, demonstrating their cross-disciplinary impact and relevance.
NIW Approval and Outlook
The I-140 NIW petition was filed on January 28, 2025. USCIS issued an RFE on March 28, 2025, and the case was approved on August 23, 2025. The RFE response included additional evidence of his publications, citations, patents, and recognition, all of which established that he was well-positioned to continue advancing his proposed endeavor.
With NAILG’s support, the client successfully secured NIW approval and can now continue his research in the United States. His work in semiconductor yield enhancement and nanochemistry promises to support national priorities in technology, innovation, and economic security.
