Success Story: Our Expert Team Secured NIW Victory for a Postdoctoral Scholar From China

Client’s Testimonial:

“Thank you very much for the assistance on my I-140 NIW case – I had a very good experience! I want to mention in particular that the reference letters and petition letter first drafts were of high quality, as both of my references noted. At the later stage, though, when there were multiple messages going on and one got missed and led to some delays, the lawyer was able to address it quickly once I followed up!”

On March 20^th, 2025, we received another EB-2 NIW (National Interest Waiver) approval for a Postdoctoral Scholar in the Field of Polymer Materials (Approval Notice).

General Field: Polymer Materials

Position at the Time of Case Filing: Postdoctoral Scholar

Country of Origin: China

State of Residence at the Time of Filing: California

Approval Notice Date: March 20^th, 2025

Processing Time: 6 months, 3 days (Premium Processing Upgrade Requested)

Case Summary:

We are proud to share the success story of a polymer materials researcher from China whose I-140 NIW (National Interest Waiver) petition was approved after 6 months and 3 days, following an upgrade to premium processing. This case reflects how targeted scientific achievements in cutting-edge technology sectors can meet the national interest waiver criteria.

Our client, who holds a Ph.D. in chemical engineering, focuses on advancing fabrication processes and materials for next-generation microelectronic chips. Her research specifically targets the development of high-precision patterning techniques with polymer-based innovations to enhance the high-volume manufacturing of advanced semiconductor nodes. These contributions are pivotal to strengthening the U.S. semiconductor industry and supporting national technology leadership.

Her petition, filed under the EB-2 NIW category, presented evidence of:

● 13 peer-reviewed journal articles, 1 conference paper, and 3 conference abstracts,

● A total of 323 citations, underscoring the global influence of her work,

● Peer review service for reputable journals in polymer chemistry and nanotechnology, with at least 3 completed reviews,

● At least 6 papers recognized among the top 10–20% most cited in the field of materials science for their respective publication years.

We also demonstrated that her research has been widely applied by independent investigators across academia and national laboratories. Notably, her innovations in polymer materials and nanofabrication processes have been utilized in semiconductor surface modification, selective deposition, and enabling biophysics research. These findings are not only foundational to the U.S. microelectronics sector but have also been leveraged by prominent research institutions.

Her work has attracted funding from leading U.S. federal agencies, including the National Science Foundation and the Department of Energy, further validating its national importance and relevance to U.S. strategic goals in energy, technology, and manufacturing resilience.

Two letters of recommendation from field experts supported her petition, reinforcing the value of her contributions.

We are honored to have supported this exceptional researcher in her immigration journey. Her work stands to significantly benefit the U.S. economy and scientific progress in microelectronics, and we are excited to see how her continued efforts will contribute to semiconductor innovation.
