Case Summary:

We are proud to share the successful approval of an EB-2 NIW (National Interest Waiver) petition for a postdoctoral fellow originally from Brazil, whose cutting-edge work in the field of endocrine cancer is shaping the future of cancer diagnostics and therapy. At the time of filing, the client was conducting research at a renowned U.S. cancer institute, with a specialized focus on circulating tumor DNA (ctDNA) as a means of identifying molecular residual disease in cancer patients.

Transformative Research in Endocrine Oncology

The client’s primary research involves the validation and clinical application of ctDNA to detect residual disease and determine patient-specific therapeutic responses in endocrine cancers. This work significantly contributes to improving recurrence-free survival and overall outcomes for patients undergoing chemotherapy and immunotherapy. Her efforts include coordinating multi-institutional clinical trials, analyzing tumor genetic profiles, and optimizing treatment strategies for both malignant and benign adrenal lesions.

Credentials That Reflect Extraordinary Promise

With an extensive academic background in endocrinology and molecular biology, the client has authored 18 peer-reviewed journal articles, including several first-authored works, 20 conference abstracts, one preprint, and a book chapter. Her work has been published in high-impact journals such as Science Advances, Cancers, and The Lancet Oncology, underscoring the broad recognition of her contributions within the scientific community.

Her research has been cited 281 times, including several papers ranking in the top 1%, 10%, and 20% most-cited articles in her field for their publication years. In addition, she has contributed peer reviews to leading journals, demonstrating her standing as a trusted expert in endocrine oncology.

Expert Support and Endorsement

In support of her petition, one recommender wrote:

“Her work is pioneering in the integration of circulating tumor DNA with advanced cancer therapies, which has the potential to revolutionize our approach to detecting and managing residual disease. This is precisely the kind of work that elevates U.S. leadership in medical biotechnology and precision oncology.”

This testimony reflects the widespread acknowledgment of the client’s role in enhancing U.S. research capacity in cancer detection and treatment.

National Impact and Policy Relevance

We demonstrated in the petition that the client’s work directly advances critical and emerging technologies as outlined by the National Science and Technology Council. Her research in ctDNA analysis intersects with core national objectives such as public health improvement, bioinformatics innovation, and enhanced precision in therapeutic development—all areas deemed essential to national security and economic competitiveness.

A Strategic Win with NAILG

With the help of the North America Immigration Law Group (NAILG), the client filed her EB-2 NIW petition on October 28, 2024. The petition was approved on July 23, 2025—an efficient and timely success following our carefully crafted response to the unique details of her case. We are honored to have supported her in advancing her career and continuing research that holds great promise for cancer patients nationwide.
