Client’s Testimonial:
“It was an absolute pleasure working with you”
On April 8th, 2025, we received another EB-2 NIW (National Interest Waiver) approval for a Postdoctoral Scholar in the Field of General Physics (Approval Notice).
General Field: General Physics
Position at the Time of Case Filing: Postdoctoral Scholar
Country of Origin: China
Country of Residence at the Time of Filing: China
Approval Notice Date: April 8th, 2025
Processing Time: 58 days (Premium Processing Requested)
Case Summary:
A physicist based in China, specializing in granular materials, living matter, and fluid dynamics, contacted our law firm to pursue an EB-2 National Interest Waiver (NIW) petition. Recognizing the national relevance of his work, we crafted a tailored legal strategy that emphasized both his scientific impact and his contributions to U.S. interests. At his request, we filed the petition with premium processing and ensured all supporting evidence aligned with USCIS standards.
The client’s proposed endeavor involves conducting experiments and building theoretical models to better understand the behavior of granular materials and living matter, especially as they interact with fluids. His research addresses important challenges in regenerative medicine, sustainable engineering, infrastructure durability, and energy efficiency—all areas closely tied to U.S. health, environmental, and economic priorities.
We strategically highlighted the following accomplishments to demonstrate his qualifications:
- 2 first-authored peer-reviewed journal articles, 1 first-authored peer-reviewed conference article, and 9 conference abstracts, 8 of which were first-authored.
- 2 granted patents in vibration control systems.
- A citation count of 207, reflecting strong scholarly impact in applied physics.
- Publications in top-ranked journals, including one listed among the top five in Nonlinear Science.
- Two articles were recognized in the top 10% of most cited Physics papers for their year by ESI.
Our client has pioneered methods in vibration reduction using nonlinear energy sinks (NES) and developed transmissibility models based on nonlinear frequency-response functions (NOFRFs). His work contributes to practical engineering problems in aerospace, civil infrastructure, and materials science, with applications ranging from spacecraft stabilization to seismic vibration control.
To further strengthen the case, we submitted four recommendation letters, three of which came from independent experts. These letters validated the influence of his work and its national significance. One expert noted:
“[Client’s] research is crucial to the US, as it enhances the reliability of spacecraft, streamlining operations, and reducing repair costs by minimizing vibrations. This not only ensures the safety and comfort of personnel, allowing them to focus on scientific discoveries rather than maintenance, but also offers environmental benefits. Specifically, vibration mitigation leads to quieter, more energy-conserving systems, aligning with national regulatory goals.”
His research also offers real-world solutions in cardiovascular health, clean manufacturing, and climate-related disaster prevention, directly benefiting public well-being and national resilience.
We demonstrated that waiving the labor certification and job offer requirements would serve the national interest. With premium processing, the petition was approved in just 58 days.
We are proud to have guided this accomplished physicist through the NIW process. His innovative research and growing impact make him a valuable contributor to scientific progress in the United States. We thank him for entrusting our team with his petition and wish him continued success.
