Client’s Testimonial:

"Thank you for all your help with the I-140 filing!”

On April 8^th, 2026, we received another EB-2 NIW (National Interest Waiver) approval for a Postdoctoral Scholar in the Field of Immunotherapy (Approval Notice).

General Field: Immunotherapy

Position at the Time of Case Filing: Postdoctoral Scholar

Country of Origin: South Korea

Approval Notice Date: April 8^th, 2026

Processing Time: 9 months, 30 days (Premium Processing Requested)

Case Summary:

A Postdoctoral Scholar from South Korea turned to the North America Immigration Law Group (Chen Immigration Law Associates) for help presenting a NIW case built around her work in immunotherapy. Her petition was approved on April 8, 2026, after 9 months and 30 days with Premium Processing. At the time of filing, she focused on developing improved treatment strategies for difficult-to-treat cancers.

Her proposed endeavor centered on using advanced computational modeling and bioengineering techniques to expand treatment options, improve patient survival, and enhance the quality of life for oncology patients. The petition explained that her ongoing work included improving the safety profiles of potent immunotherapies through computationally designed self-regulation and engineering highly targeted cellular therapies for aggressive, hard-to-treat cancers. These projects directly addressed two major goals in modern oncology: making treatments more effective and significantly reducing harmful side effects.

To show that she was well-positioned to advance this endeavor, we highlighted a focused record of achievement. At filing, her work included 4 peer-reviewed journal articles, 4 published abstracts, and 32 citations. The petition also noted that one of her papers ranked among the top 10% most cited Immunology articles for its publication year, an objective sign of strong early influence in the field.

The case further emphasized that her research had already actively informed the work of independent scientists. The petition described how other researchers relied on her foundational methodologies to advance their own complex cellular studies and longitudinal experiments, proving her contributions extend far beyond mere publication. Furthermore, we documented that her highly impactful work has garnered support from major funding sources, including the National Institute of Diabetes and Digestive and Kidney Diseases and the American Heart Association.

This approval reflects how a well-prepared NIW petition can connect highly technical research to broader national needs. By clearly showing the value of her immunotherapy research to improving cancer treatment and patient outcomes, we were pleased to help secure this successful result.
