Success Stories: Iranian PhD Student in Materials Science Secures NIW Approval without any RFE

Client’s Testimonial:

“I am truly grateful for the outstanding support and guidance I received throughout my NIW petition process. The team demonstrated deep expertise in both immigration law and the scientific aspects of my case. They crafted a compelling petition that effectively highlighted the national importance of my research in materials science and biomedical implants. The entire process was smooth and transparent, and I was thrilled to receive approval without any RFE. I highly recommend their services to any researcher pursuing a similar path.”

On April 4^th, 2025, we received another EB-2 NIW (National Interest Waiver) approval for a Ph.D. student in the Field of Materials Science (Approval Notice).

General Field: Materials Science

Position at the Time of Case Filing: Ph.D. Student

Case Summary:

An Iranian Ph.D. student in materials science approached our firm to pursue permanent residency through the EB-2 NIW (National Interest Waiver) category. His research focuses on enhancing the performance and durability of biomedical implants using advanced manufacturing and materials design. After reviewing his credentials and scientific record, we developed a petition strategy emphasizing the national importance of his proposed endeavor.

The client’s proposed research centers on designing and analyzing corrosion-resistant alloys manufactured via additive manufacturing (AM). These materials are crucial to the development of safer, longer-lasting biomedical implants. His work seeks to reduce the high rate of implant failure, which leads to costly and risky revision surgeries. By improving corrosion resistance and overall implant longevity, his research directly supports U.S. healthcare goals and strengthens biomedical innovation.

His work also advances critical technology areas identified by U.S. agencies, including additive manufacturing, materials science, and biomedical engineering. In particular, his alloy design for AM processes addresses manufacturing flexibility and customization for patient-specific implants.

To support his case, we highlighted the following achievements:

● 7 peer-reviewed journal articles, with 4 as first author, published in respected materials science and engineering journals

● 110 citations, demonstrating his research is regularly referenced and relied upon by other scholars

● One publication ranked in the top 10% of most-cited articles in materials science for its publication year

● Research supported by prestigious grants, including the NSERC Alliance Missions Grant and the Canada First Research Excellence Fund (CFREF)

His publications have influenced work in fields ranging from corrosion science to biomaterials development. His methods contribute to designing longer-lasting, safer implants that align with national efforts to improve healthcare efficiency and reduce long-term surgical costs.
The petition was further supported by two expert recommendation letters, which reinforced the originality of his research and its value to

U.S. technological interests. One expert stated:

“[Client’s] work on the development of plant-based corrosion-resistant coatings, in addition to safeguarding critical areas of industry and infrastructure, is representative of a substantial shift toward sustainable industrial processes and provides an extra layer of security in industries such as agriculture and food processing, where the safety of equipment and products is paramount.”

Following our strategic preparation and thorough legal documentation, his I-140 NIW petition was approved in 1 year and 4 months, with no Request for Evidence (RFE) issued. We are proud to have supported his journey and look forward to his continued contributions to biomedical materials research and healthcare innovation in the United States.
