Posted by wegreened on November 4, 2026 in NIW,Chemistry (Organic Chemistry, Biochemistry, Biochemical Engineering, Electrochemical Engineering, Physical Chemistry, Macromolecular Engineering, Polymer Chemistry, Chemical Engineering)

Client’s Testimonial:

“I can’t make it without their professional support!”

On September 23^rd, 2026, we received another EB-2 NIW (National Interest Waiver) approval for an R&D Engineer in the Field of Chemical Engineering (Approval Notice).

General Field: Chemical Engineering

Position at the Time of Case Filing: R&D Engineer

Country of Origin: Taiwan

State of Residence at the Time of Filing: California

Approval Notice Date: September 23^rd, 2026

Processing Time: 7 months, 4 days (Premium Processing Upgrade Requested)

Case Summary:

The client, a chemical engineering expert holding a Ph.D., has focused his research on overcoming these industrial challenges by designing functional bio-based polymers and modern recycling processes.

For his I-140 EB-2 National Interest Waiver (NIW) petition, the client proposed to continue his research on designing functional polymers and advanced manufacturing technologies. Rather than focusing solely on isolated laboratory techniques, our petition highlighted how this broader research direction advances federal priorities.

Turning Research Experience into Evidence of Future Potential

The client’s scholarly record included 14 peer-reviewed journal articles (5 of them first-authored) and 3 first-authored conference abstracts. His published work had accumulated 273 citations from researchers around the world, and he had completed at least 20 peer reviews for authoritative scientific journals in chemical engineering and polymer science. Additionally, his research had received major research grant funding from prestigious federal institutions, including the National Science Foundation (NSF) and the U.S. Department of Energy (DOE).

To further reinforce his positioning, the petition was supported by 4 recommendation letters from independent and leading experts in chemical engineering who attested to the major significance, clinical and industrial utility, and national importance of his polymer innovations:

"[Client’s] productive research output and publications in esteemed venues are yet another example of his expertise and valuable contributions to chemical engineering."

A Successful NIW Outcome

Despite receiving an initial Request for Evidence (RFE), North America Immigration Law Group submitted a robust response demonstrating the national importance of the client's endeavor, his strong record of past success, and his well-positioned standing to advance sustainable polymer technologies. USCIS approved his I-140 NIW petition, validating the substantial merit of his research and enabling him to continue contributing to U.S. material science and sustainable manufacturing.

We congratulate the client on this achievement and wish him continued success as he advances his work in chemical engineering.
