Posted by wegreened on October 13, 2026 in NIW, General Medicine (Public Health, Clinical Research, Infectious Diseases, Vaccines, Virology, Epidemiology, Clinical Psychology, Psychiatry)

Client’s Testimonial:

“Every step was professional. Thank you for helping me through this process.”

On September 4^th, 2026, we received another EB-2 NIW (National Interest Waiver) approval for a Postdoctoral Research Associate in the Field of Clinical Research (Approval Notice).

General Field: Clinical Research

Position at the Time of Case Filing: Postdoctoral Research Associate

Country of Origin: Iran

Approval Notice Date: September 4^th, 2026

Processing Time: 19 months, 18 days (Premium Processing Upgrade Requested)

Case Summary:

The client holds an MD degree and is currently employed conducting clinical research at a major U.S. university. Operating in the field of clinical research, the client’s proposed endeavor focuses on continuing her research on increasing the survival rate and quality of life of patients with lethal pancreatic cancer. This work directly addresses vital public health priorities by establishing earlier diagnostic precision, ultimately reducing downstream healthcare costs and improving long-term patient outcomes.

To demonstrate that the client satisfies the Matter of Dhanasar framework, our legal team built an evidentiary portfolio showing that her research record represents field-wide influence rather than baseline clinical output:

Publication Record: Authorship of 13 peer-reviewed journal articles (5 of them first-authored), reflecting a consistent record of scholarly dissemination in top medical journals.

Citation Impact & Percentiles: Accumulation of 81 citations across her published body of work. Rather than presenting raw figures alone, we provided bibliometric data proving that five of her articles rank in the top 10% of most-cited clinical medicine papers for their respective publication years.

Field Reliance: Concrete evidence demonstrating that independent international researchers actively rely on her clinical findings and radiological strategies to evaluate critical care medication safety, neuroimaging pathways, and diagnostic classifications.

Evaluative Standing: Completion of at least 1 peer review to date for an authoritative journal in her field, confirming that editorial boards recognize her specialized medical expertise.

The petition was further corroborated by 2 letters of recommendation from distinguished experts in the field who verified the practical necessity and national importance of the client's research.

By connecting the client's diagnostic radiology frameworks, independent scientific reliance, and national priorities in oncology and liver disease management, we proved that waiving the job offer requirement served the national interest. USCIS approved the client's I-140 NIW petition in over 19 months.
