Success Story: NIW Approval Follows a Targeted RFE Response for a Materials Engineering Researcher
Client’s Testimonial:
"Thank you very much for your guidance and support throughout the process, particularly in preparing the RFE response.”
On August 19th, 2026, we received another EB-2 NIW (National Interest Waiver) approval for a Researcher in the Field of Materials Engineering (Approval Notice).
General Field: Materials Engineering
Position at the Time of Case Filing: Researcher
Country of Origin: Nepal
Country of Residence at the Time of Filing: South Korea
Approval Notice Date: August 19th, 2026
Processing Time: 10 months, 17 days (Premium Processing Requested)
Case Summary:
The decisive stage of this NIW case began when USCIS issued a Request for Evidence (RFE) on April 7th, 2026. USCIS had already accepted the substantial merit and national importance of the client's work in materials engineering, leaving the second prong of the Dhanasar framework as the central issue. Specifically, the officer sought stronger evidence that the client was well positioned to continue advancing research on robust multifunctional materials for extreme environments. North America Immigration Law Group (Chen Immigration Law Associates) strategically built the response around this single remaining point of contention.
One priority was to give the client's scholarly influence much greater context. The updated record showed 69 peer-reviewed journal articles, 9 patents, and 1,995 citations, of which 1,652 were independent. Additional field-level data placed the client among the top 2% of researchers in his field based on citation impact and research productivity. This evidence helped establish that his prior work had achieved recognition extending substantially beyond his own research collaborations.
The response moved beyond mere citation metrics to demonstrate tangible, practical impact. We provided concrete examples of independent scientists relying on the client's findings to advance research in advanced ceramics, optical technologies, and corrosion-resistant materials. Addressing the forward-looking concerns of the RFE, we detailed the client's updated research plan for developing highly resilient materials for extreme environments, supported by ongoing U.S.-based collaborations. Expert testimony further reinforced his multidisciplinary capability to drive physical and computational innovations, directly connecting his established record to broad applications across the aerospace, energy, and advanced manufacturing sectors.
The strategy ultimately centered on a simple distinction: past accomplishments showed what the client had already achieved, while independent reliance, ongoing collaborations, and concrete research plans showed why he was positioned to continue making progress. The favorable decision brought the RFE stage to a successful close and marked an important milestone in the client's continued work in advanced materials engineering.
