Success Story: Strengthening Critical Electronic Systems through an I-140 NIW Approval for an Electrical Engineering Expert
Client’s Testimonial:
"The case preparation was good. If my I-140 is approved, I would definitely like to retain WeGreened."
On May 18th, 2026, we received another EB-2 NIW (National Interest Waiver) approval for a PhD Candidate in the Field of Electrical Engineering (Approval Notice).
General Field: Electrical Engineering
Position at the Time of Case Filing: PhD Candidate
Country of Origin: Bangladesh
State of Residence at the Time of Filing: Michigan
Approval Notice Date: May 18th, 2026
Processing Time: 25 months, 20 days
Case Summary:
Electromagnetic interference may be invisible, but in power electronic systems, its impact can be significant. For automotive systems, avionics, mission-critical space applications, and medical equipment, reliable electronic control is essential to safety, performance, and long-term technological progress. This was the foundation of the client’s I-140 NIW petition.
The client, an expert in electrical engineering, proposed to continue research on developing methods to characterize electromagnetic interference in power electronic systems and identify optimal control and mitigation mechanisms. The client plans to continue advancing electromagnetic interference (EMI) modeling, filtering, and mitigation methods for wide-bandgap power electronic systems.
To demonstrate national importance, the petition connected the client’s work to several areas where the United States has a strong public and economic interest, including electric vehicles, aviation, space systems, medical equipment, naval power systems, and emerging power-management technologies. We showed that the client’s research was not merely technical in nature, but relevant to improving the reliability and safety of systems where electronic malfunction can have serious consequences.
The petition also established that the client was well-positioned to advance this endeavor. The client’s record included 9 peer-reviewed conference articles, 5 of them first-authored, 1 accepted conference article, and 1 patent application. The client’s publications had received 23 citations, which we presented as evidence that other researchers had used the client’s work to study EMI mitigation, wide-bandgap devices, power converter design, electric ship technologies, and medical-device safety. Rather than relying on the citation count alone, the petition explained how these citations reflected practical reliance on the client’s methods in related engineering research.
Peer trust was another important part of the case. The client had completed at least 17 peer reviews, showing that authoritative venues trusted the client to evaluate technical work in electrical engineering and power electronics.
Four recommendation letters from experts in the field further supported the client’s qualifications, technical contributions, and ability to continue advancing EMI characterization and mitigation research.
“[Client’s] work has benefits for the United States’ electrical infrastructure through his professional work, which serves as proof that he is capable of producing theoretical and practical results in the discipline.”
Through a carefully organized I-140 NIW petition, we demonstrated that the client’s work addressed a nationally important engineering problem and that the client’s publication record, citation history, peer-review service, patent-related work, funding support, and expert endorsements collectively showed the client’s significance in the field. We congratulate the client on this I-140 NIW approval and wish the client continued success in advancing safer and more reliable electronic control systems.
