Client’s Testimonial:

"I had a very positive experience working with Chen Immigration on my NIW petition. Their team was responsive and professional throughout the process. They guided me well at every stage, and I am glad that my NIW was approved with their help. I highly recommend Chen Immigration to anyone seeking strong legal support for an NIW case.”

On February 25^th, 2025, we received another EB-2 NIW (National Interest Waiver) approval for a Visiting Scientist in the Field of Electrical Engineering (Approval Notice).

General Field: Electrical Engineering

Position at the Time of Case Filing: Visiting Scientist

Country of Origin: India

State of Residence at the Time of Filing: Maryland

Approval Notice Date: February 25^th, 2025

Processing Time: 16 months, 29 days

Case Summary:

Drawing on our extensive experience and a proven track record of more than 32,000 approved cases, our team recently secured an I-140 National Interest Waiver approval for the client, an electrical engineering expert focused on advanced electrochemical methods for next-generation materials.

Background & Field of Expertise

The client holds a Ph.D. in engineering (micro and nanoscale systems) and has built specialized expertise in electrical engineering. The proposed endeavor is to continue research on deploying diverse electrochemical characterization tools and electrochemical impedance spectroscopy methods to develop optimal parameters for additive manufacturing, with the goal of designing functional surfaces that enable high performance, less corrosive steels for orthopedic medical devices and automobile applications.

The client is currently employed as a visiting scientist at a U.S. federal public health agency. This position closely aligns with the client’s research focus on evaluating materials performance and reliability in applications where safety, durability, and corrosion resistance are critical.

Strong Evidence of Research Excellence

To demonstrate the client’s prominent standing in the field, we highlighted

10 peer-reviewed journal articles (2 first-authored, 3 co-first-authored)
3 peer-reviewed conference articles (1 first-authored)
233 citations to the client’s published work
At least 157 completed peer reviews to date
Major funding support from federal research agencies

In an NIW case, these indicators are most persuasive when they show independent reliance and sustained peer trust. The citation record reflects that other researchers have repeatedly relied on the client’s findings as a foundation for related work. The high volume of peer review invitations further demonstrates confidence in the client’s technical judgment and credibility, since journals and conferences typically reserve review responsibilities for specialists who can evaluate methods and results at a high level. We also framed the client’s research as directly tied to real world performance needs, emphasizing how improved corrosion resistance can support safer medical devices and more reliable materials in automotive settings.

The Approval

The petition was approved, underscoring the effectiveness of presenting a clear NIW narrative supported by objective indicators of expertise, independent reliance, and sustained peer trust. This approval highlights how electrochemical characterization and impedance-based methods, when tied to additive manufacturing improvements for corrosion-resistant steels, can satisfy NIW criteria through a well-supported link between technical innovation and meaningful U.S. impact.
