Client’s Testimonial:

"Thank you for your help with my EB2 NIW petition. I really appreciate the time and effort you put into preparing my case. The communication was clear, and you were always quick to respond to my questions, which made the process a lot less stressful.

I felt that you understood my background well and did a great job highlighting my strengths in the petition. The documents were well-organized, and everything felt professionally handled. Overall, I’m happy with how everything went and grateful for your support throughout the process.”

On March 25^th, 2026, we received another EB-2 NIW (National Interest Waiver) approval for a Ph.D. Student in the Field of Cancer Biology (Approval Notice).

General Field: Cancer Biology

Position at the Time of Case Filing: Ph.D. Student

Country of Origin: Cambodia

State of Residence at the Time of Filing: Texas

Approval Notice Date: March 25^th, 2026

Processing Time: 9 months, 25 days (Premium Processing Requested)

Case Summary:

At the time of filing, our client was a Ph.D. student working in the field of cancer biology. The proposed endeavor centered on investigating the function of both protein-coding and non-protein-coding genes involved in cancer growth, malignancy, and drug resistance. Using molecular biology techniques and genetic modification methods, the research aimed to fill important knowledge gaps regarding the mechanisms that drive cancer progression, support the development of improved therapeutics, reduce therapy resistance, improve patient survival, and enhance quality of life after treatment.
Among the strongest objective indicators of the case were the following:

8 peer-reviewed journal articles
201 citations
At least 3 completed peer reviews
Research funding support connected to the National Institutes of Health and the Governor’s University Research Initiative from the State of Texas

This approval shows how a carefully prepared NIW case can frame cancer biology research in a way that is both scientifically rigorous and legally persuasive. Here, the evidence supported all key points of the NIW standard: the endeavor had substantial merit and national importance, the client was well-positioned to advance it, and waiving the job offer and labor certification requirements would benefit the United States.

We are pleased that the North America Immigration Law Group (Chen Immigration Law Associates) could help present this researcher’s record and future plans effectively. We extend our congratulations to our client and look forward to the continued impact of this work on cancer therapeutics, treatment resistance, and patient outcomes in the United States.
