Success Story: NIW Approved Despite an RFE for a Materials Science Researcher Advancing Wide Bandgap Semiconductors
Client’s Testimonial:
"Great experience working with North America Immigration Law Group. The team’s responsiveness is invaluable throughout this process. While the current adjudication process has changed very much from the early 2020s and now requires even greater personal inputs, it is always a big advantage to have experienced attorneys at Chen to support you throughout the process.”
On March 2nd, 2026, we received another EB-2 NIW (National Interest Waiver) approval for a Graduate Research Assistant in the Field of Materials Science and Engineering (Approval Notice).
General Field: Materials Science and Engineering
Position at the Time of Case Filing: Graduate Research Assistant
Approval Notice Date: March 2nd, 2026
Processing Time: 16 months, 13 days (Premium Processing Upgrade Requested)
Case Summary:
We are pleased to share the success of an I-140 EB-2 National Interest Waiver (NIW) approval for the client, a materials science and engineering researcher working on next-generation semiconductor devices. The case received a Request for Evidence, but the petition was ultimately approved after a focused response that clarified the national importance of the work and the client’s strong positioning to advance it.
The Endeavor
The client holds an M.S. in materials science and engineering and is currently conducting research in the United States in a university research setting. The proposed endeavor is to continue developing state-of-the-art heterostructures based on wide bandgap semiconductor thin films for novel devices with enhanced power handling and speed capabilities. We framed this work as nationally important because wide bandgap device innovation is foundational to more efficient power electronics and faster, more reliable wireless communication systems, where performance, thermal stability, and device robustness matter.
Evidence of Influence and Recognition
To show the client is well-positioned, we presented objective indicators of productivity and independent research uptake, while also explaining how USCIS should interpret the metrics rather than treating them as self-evidently sufficient:
- Publications: 4 peer-reviewed journal articles, 2 peer-reviewed conference articles, 1 accepted first-authored article, 4 conference abstracts (1 first-authored), and 1 book chapter
- Citations: 37 citations to the client’s published work
- Peer review: At least 2 completed reviews, reflecting early professional trust from selective venues
Field context: We highlighted that two publications ranked among the more highly cited papers in Materials Science for their publication years, with one in a top 10% tier and another in a top 20% tier, which helps normalize impact beyond raw citation totals
We also explained that, in semiconductor research, influence is best demonstrated when other researchers adopt methods, structures, or results as reference points for further device development. The citation record and citation-percentile context supported that the client’s work is being used by independent researchers, not only published.
National-Interest Alignment and Competitive Support
The petition further documented major research support tied to nationally relevant technology development, including funding from the Defense Advanced Research Projects Agency, the Air Force Office of Scientific Research, and the Semiconductor Research Corporation, among others. We used this evidence to reinforce that the client’s research direction aligns with high-priority innovation needs, especially where advanced semiconductor materials and devices support both civilian and mission-critical applications.
Support from Experts
To strengthen the case record, we submitted 2 letters of recommendation from established experts. These letters helped translate specialized device and materials work into clear significance by explaining why the client’s heterostructure research is valuable to the broader field and why continued progress in this area benefits U.S. technological capability.
“It is thus imperative that he be allowed to carry out his research uninterruptedly so that the United States is able to fully benefit from its value.”
The Result
After responding to the RFE, USCIS approved the NIW petition. This outcome reflects a cohesive presentation of national importance, credible forward momentum, and independent reliance demonstrated through publications, citations, and selective peer recognition. We look forward to the client’s continued contributions to wide bandgap semiconductor devices that strengthen next-generation power electronics and wireless communication systems in the United States.
