Posted by wegreened on November 2, 2026 in NIW, Acoustics

Client’s Testimonial:

“Thank you very much for all your support throughout my NIW process!”

On September 21^st, 2026, we received another EB-2 NIW (National Interest Waiver) approval for a Postdoc Researcher in the Field of Acoustic Devices (Approval Notice).

General Field: Acoustic Devices

Position at the Time of Case Filing: Postdoc Researcher

Country of Origin: China

State of Residence at the Time of Filing: Virginia

Approval Notice Date: September 21^st, 2026

Processing Time: 25 months, 1 day (Premium Processing Upgrade Requested)

Case Summary:

Holding a Ph.D. in acoustics, the client focuses his research on utilizing theory to develop advanced acoustic and phononic devices. His work directly advances federally recognized critical and emerging technologies and has been backed by major research grant funding from the National Science Foundation (NSF)’s Division of Civil, Mechanical, and Manufacturing Innovation.

Strategic Metrics & Scholarly Credentials

To demonstrate that the client was well-positioned to advance his endeavor under Matter of Dhanasar, our firm structured a comprehensive evidentiary record highlighting his scientific standing:

250 total citations accrued across his published body of work from independent researchers globally
8 peer-reviewed journal articles (4 first-authored), 1 peer-reviewed conference article, and 7 conference abstracts (4 first-authored)
At least 30 completed peer reviews for authoritative scientific journals in acoustics, physics, and engineering
4 highly cited publications, including 3 ranking among the top 10% and 1 in the top 20% of most-cited engineering articles for their respective publication years

Rather than presenting raw citation metrics as self-evidently sufficient, our legal team provided detailed bibliometric contextualization for the USCIS adjudicator. We established that independent research teams around the world actively rely on his wave-matter interaction models. Furthermore, his extensive peer-review service demonstrated that leading journal editors consistently depend on his technical authority.

RFE Resolution & Case Approval

Following an initial Request for Evidence (RFE) questioning the client's qualifications, we submitted a robust response demonstrating his established field influence, independent citation reliance, and federal research support. USCIS approved the I-140 NIW petition, validating the national importance of his endeavor. We congratulate the client on this achievement and look forward to his ongoing contributions to acoustic devices and quantum technology in the United States.
