Success Story: NIW Approved Without RFE for a Postdoctoral Fellow from Sri Lanka
Client’s Testimonial:
"Thank you for helping us throughout this process. I really appreciate it.”
On February 4th, 2026, we received another EB-2 NIW (National Interest Waiver) approval for a Postdoctoral Fellow in the Field of Biophysical Chemistry (Approval Notice).
General Field: Biophysical Chemistry
Position at the Time of Case Filing: Postdoctoral Fellow
Country of Origin: Sri Lanka
State of Residence at the Time of Filing: Missouri
Approval Notice Date: February 4th, 2026
Processing Time: 20 months, 15 days (Premium Processing Upgrade Requested)
Case Summary:
Some research starts with a basic question—what does a protein do in a real biological environment?—and ends with a roadmap for how to target that protein in therapy. This NIW approval highlights the client, a biophysical chemistry researcher whose work uses protein chemistry and bioinformatics to analyze protein behavior, identify target proteins, and develop new constructs that can support novel therapeutics, precision-targeted drug delivery systems, and advanced biomaterials.
The client holds a Ph.D. in chemistry and, at the time of filing, was conducting research in the United States at a U.S.-based research university. The client’s ongoing work aligns with the proposed endeavor through research on protein transport across membranes by bacterial pathogens, using integrated biochemical, biophysical, structural, and genetic approaches, with plans to continue publishing peer-reviewed research in the same technical direction.
How the Case Was Framed
North America Immigration Law Group (Chen Immigration Law Associates) structured the NIW presentation around a straightforward logic for a non-specialist adjudicator:
- The endeavor matters at scale because protein-behavior insights are upstream inputs to modern therapeutic development, including target identification and construct design.
- The client is well-positioned because the record already shows peer-validated output and measurable independent uptake.
- Waiving labor certification benefits the United States by allowing the client to continue advancing a research program that is not tied to a single job title, but to a continued line of biophysical chemistry and bioinformatics work with broad biomedical applications.
Evidence of Credibility and Momentum
In NIW cases, metrics cannot be treated as automatically sufficient. We therefore tied each indicator to what it signals in practice: selection by peer review, independent reliance, and external confidence.
The record documented:
- Publication record: 6 peer-reviewed journal articles (3 first-authored)
- Citation reliance: 27 citations to the published body of work
Research support: major funding tied to the National Institutes of Health (NIH) and the National Science Foundation (NSF), used as an objective anchor that the work has been competitively evaluated and backed
The filing did not rely on a documented peer-review-service count as a primary metric in this record. Instead, it emphasized publication selectivity, independent citation uptake, and competitively reviewed funding as the clearest third-party indicators of standing and forward momentum.
Expert Recommendation Letters
To translate technical contributions into clear significance, the petition included four letters of recommendation, including independent advisory perspectives. These letters were used to connect the client’s protein-focused discoveries and methods to practical downstream value for therapeutic targeting, engineered constructs, and biomaterials development.
“Hence, it is in the interest of the United States to support [Client’s] research and leverage her grasp of biophysical chemistry and special emphasis on protein chemistry for infectious disease prevention and preparedness.”
The Result
USCIS approved the I-140 EB-2 National Interest Waiver petition without an RFE, reflecting a record that connected the client’s protein chemistry and bioinformatics endeavor to nationally important biomedical innovation and demonstrated strong positioning through peer-reviewed authorship, independent reliance via citations, and funding-backed validation.
