Success Stories: Without any Request for Evidence [RFE], A Postdoctoral Researcher from China in the Field of Fluid Dynamics Achieves NIW Approval despite waiting for a Long Time. Thanks To Our Intelligence and Guidance.
Client’s Testimonial:
“Thank you so much for sharing such wonderful news for me and my family! Your service is way beyond my expectations! Perfect! Thank you so much again!”
On March 15th, 2025, we received another EB-2 NIW (National Interest Waiver) approval for a Postdoctoral Researcher in the Field of Fluid Dynamics (Approval Notice).
General Field: Fluid Dynamics
Position at the Time of Case Filing: Postdoctoral Researcher
Country of Origin: China
State of Residence at the Time of Filing: Illinois
Approval Notice Date: March 15th, 2025
Processing Time: 15 months, 15 days
Case Summary:
With a Ph.D. in science and engineering and fundamental research experience, undoubtedly, our client possesses the ability to advance in the field of fluid dynamics. When he contacted our law firm to file an I-140 NIW (National Interest Waiver) petition on his behalf, we delved more into his degrees and diplomas, and after thoroughly evaluating his credentials, we established that we would lead him to NIW success and countersigned the retainer agreement.
We intended to prove that he is an essential researcher in his field; therefore, we added essential attributes to his NIW (National Interest Waiver) petition packet. We noted that his work:
- Cited 20 times by dependent and independent researchers, demonstrating that his publications are widely recognized and relied upon in his chosen field.
- His contributions to peer-reviewed conference articles resulted in 6 peer-reviewed journal articles (3 of them first-authored) and 14 conference proceedings (7 of them first-authored) (2 of them accepted).
- His study has been supported by funding from the Japan Society for the Promotion of Science. This society funds projects that promote research in all scientific disciplines for socioeconomic development. His research therefore serves as evidence that his work advances the current understanding of supersonic gas flow as it pertains to various industrial applications.
Moreover, our client’s proposed endeavor is to build realistic numerical lung models to visualize and analyze internal airflow to identify the optimum ventilation approaches for healthy, diseased, or injured lungs. Specifically, he intends to continue his research on building realistic numerical lung models to visualize and analyze internal airflow to identify the optimum ventilation approaches for healthy, diseased, or injured lungs.
He proposes to enhance GE Healthcare’s ventilator models to reduce mortality rates in ARDS patients, utilize numerical lung models and clinical trials for optimization, promote research through GE Healthcare’s national marketing initiatives, leverage GE Healthcare’s industry leadership for innovation, collaborate to develop cutting-edge healthcare solutions, and publish original fluid dynamics research in peer-reviewed journal and conference publications.
Our client has even received two letters of recommendation from fellow experts in his field, out of which, one of the recommenders stated:
“[Client’s] research is not only of major importance to his field, but it is also important to global public health…Through [client’s] work, these patients have access to an optimum ventilation approach that offers an efficient, soft mechanical ventilation scheme, consisting of conventional mechanical ventilation (CMV) without the harmful over-distension. It is with this in mind that I urge your office to allow him to continue his important research in the United States uninterrupted.”
Thus, our client’s education, experience, expertise, record of publication and citation, and history of successful research in the field all indicate that he is well-positioned to advance the proposed endeavor. We are pleased that our efforts and hard work, in this case, paid off well in proving that our client’s major contributions in his field of expertise make him an invaluable asset to the United States, thus, he received his NIW (National Interest Waiver) approval despite waiting for so long, but without any request for evidence [RFE]. Therefore, we thank him for choosing the North America Immigration Law Group to represent his case and wish him the very best as he continues to advance in his proposed field.
