Success Story: NIW Approved Without RFE For A Postdoctoral Associate, Thanks To Our Strategic Filing and Guidance
Client’s Testimonial:
"I had an excellent experience with Chen Immigration. Their team is professional, organized, and supportive throughout the entire process. I am very satisfied with their service and highly appreciate their guidance.”
On February 26th, 2026, we received another EB-2 NIW (National Interest Waiver) approval for a Postdoctoral Associate in the Field of Electrical Engineering (Approval Notice).
General Field: Electrical Engineering
Position at the Time of Case Filing: Postdoctoral Associate
Country of Origin: Bangladesh
State of Residence at the Time of Filing: New York
Approval Notice Date: February 26th, 2026
Processing Time: 10 months, 19 days (Premium Processing Upgrade Requested)
Case Summary:
This NIW approval recognizes the client, an electrical engineering researcher whose work strengthens power electronics by developing cost-effective, high-breakdown transistors using ultra-wide bandgap semiconductor fabrication, characterization, and device modeling. The proposed endeavor supports nationally important applications, including power grid modernization, electric vehicles, and space technologies. At the time of filing, the client was continuing this work in the United States in a research role aligned with advanced semiconductor device development.
Research with National Importance
The NIW filing framed the endeavor as nationally important because durable, high-voltage transistors are foundational components for reliable energy conversion and control. Improvements in breakdown performance, leakage behavior, and thermal reliability can translate into more robust power systems, more efficient electrified transportation, and more resilient electronics operating under harsh conditions. The petition also emphasized that the client’s work fits within U.S. priorities tied to advanced semiconductors and other critical technology areas, where engineering advances have a broad downstream impact.
Academic Contributions and Recognition
To show the client is well-positioned to advance the endeavor, the petition documented sustained peer-reviewed output and independent uptake in the field:
- 11 peer-reviewed journal articles (7 first-authored), 2 peer-reviewed conference articles (1 first-authored), and 1 first-authored abstract
- 68 citations to the published body of work
- Two publications with field- and year-normalized performance ranking among the top 10% most cited in engineering for their publication years
- Major research support from the National Research Foundation (NRF), used as an objective anchor that the work has been competitively evaluated and backed
These metrics were not treated as self-explanatory. The petition explained how an adjudicator should interpret them in context: repeated selection by rigorous peer-reviewed venues indicates consistent success under expert scrutiny, citations indicate independent reliance by other researchers who use the client’s findings to guide their own work, and field-normalized citation benchmarks help evaluate influence fairly across publication years. The record for this case did not rely on a peer-review-service count as a primary metric; instead, it emphasized publication selectivity, documented citation reliance, and funding support as objective signals of credibility and momentum.
Expert Recommendation Letters
The petition included two letters of recommendation from established experts, used to translate technical device-engineering contributions into clear significance and to corroborate that the client’s methods have been useful reference points for other researchers working on high-performance power electronics.
“Thus, [Client’s] record of achievement to date more than evidences the indispensability of his research to the USA.”
NIW Approval and Outlook
USCIS approved the I-140 EB-2 National Interest Waiver petition, reflecting a record that connected advanced transistor innovation to national-scale needs in energy reliability and electrified technologies and demonstrated strong positioning through sustained peer-reviewed authorship, independent citation reliance, and competitively reviewed research support.
