Success Story: From Biomaterials Research to Advanced Disease Imaging, Ph.D. Candidate Secures NIW Approval
Client’s Testimonial:
“Highly satisfied with the preparation process of my NIW package.”
On August 25th, 2026, we received another EB-2 NIW (National Interest Waiver) approval for a Ph.D. Candidate in the Field of Nanobiomaterials (Approval Notice).
General Field: Nanobiomaterials
Position at the Time of Case Filing: Ph.D. Candidate
Country of Origin: Iran
State of Residence at the Time of Filing: Michigan
Approval Notice Date: August 25th, 2026
Processing Time: 24 months, 23 days (Premium Processing Requested)
Case Summary:
Before pursuing research involving advanced biomedical imaging, the client had already worked across several areas of nanobiomaterials, including polymer-based biomedical materials, controlled drug delivery, encapsulation techniques, and nanoparticle carriers. This progression gave North America Immigration Law Group (Chen Immigration Law Associates) an important foundation for the NIW petition: we showed how the proposed endeavor grew naturally from the client’s established expertise in designing and characterizing materials for biomedical applications.
The next stage of that trajectory focused on non-invasive cellular and molecular imaging methods inside the body. The client proposed developing more effective and accessible cellular tracking platforms with broad diagnostic, prognostic, and therapeutic applications for major systemic diseases. Planned research included the engineering of specialized nanomaterials, advanced cellular labeling techniques, and biocompatible polymers for targeted drug delivery. The petition further connected these plans to overarching federal priorities in advanced engineering materials and biotechnology, explicitly identified as critical and emerging technology areas.
There was already substantial evidence that the client could translate specialized materials research into work useful to the broader scientific community. The client held a master’s degree in polymer engineering-processing and had authored 7 peer-reviewed journal articles, as well as 2 book chapters. His publications had accumulated 280 citations.
Scientists drew upon his work when improving interactions within polymer materials, designing hydrogels for localized cancer drug delivery, modifying polymer systems to enhance drug-release properties, and optimizing encapsulation techniques. Research associated with his work had also received support from the American Heart Association and the National Institutes of Health, further supporting the relevance of these investigations to biomedical research.
For the NIW petition, NAILG used this progression to address the Dhanasar framework as an integrated argument. The proposed imaging research was positioned in relation to major U.S. healthcare burdens, while the client’s prior publications, independent use of his findings, advanced training, and ongoing research plans demonstrated his preparation to carry the endeavor forward. The petition also explained why continued work on improved diagnostic and therapeutic technologies could benefit the United States beyond the interests of a single employer, particularly given the substantial healthcare and economic burdens associated with chronic diseases.
For this client, the NIW approval marked a transition from an already productive body of biomaterials research toward a more specialized effort involving non-invasive immune-cell imaging. It also allowed the client to continue building on the same scientific foundation that has already led other researchers to incorporate the client's materials, drug-delivery, and encapsulation findings into their own work.
