Client’s Testimonial:

"Thank you very much for your assistance and for the successful approval of my I-140 NIW petition. I truly appreciate your support throughout this process."

On May 29^th, 2026, we received another EB-2 NIW (National Interest Waiver) approval for a Gastroenterologist in the Field of Gastroenterology (Approval Notice).

General Field: Gastroenterology

Position at the Time of Case Filing: Gastroenterologist

Country of Origin: Taiwan

Country of Residence at the Time of Filing: Taiwan

Approval Notice Date: May 29^th, 2026

Processing Time: 3 months, 19 days (Premium Processing Requested)

Case Summary:

At the time of filing, the client was practicing in Taiwan and had established a career in gastroenterology, internal medicine, and clinical research. He holds an M.D., which positioned him to continue contributing to evidence-based medical research and patient care.

North America Immigration Law Group (Chen Immigration Law Associates) built the case around the client's proposed endeavor: utilizing large-scale medical record databases to investigate drug adverse effects and complications among patients with gastrointestinal diseases. The petition emphasized that real-world evidence generated from large patient populations could help physicians better understand medication risks, identify vulnerable patient groups, and improve treatment decisions.

The client's research sought to reduce preventable complications, improve medication safety, and strengthen evidence-based care by analyzing patient outcomes across large clinical datasets. This work supported national efforts to improve healthcare quality while reducing avoidable hospitalizations and healthcare costs.

The client's academic record reflected a growing impact in the field:

4 peer-reviewed journal articles
32 citations
1 paper ranked among the top 10% most-cited Clinical Medicine articles for its publication year

Later studies cited his work to better understand colorectal signet ring cell carcinoma prognosis, imaging characteristics, immunotherapy-related neurotoxicity, and treatment strategies for rare adverse events. These examples helped establish that his contributions were influencing subsequent investigations in gastroenterology, oncology, and clinical medicine. This field-wide influence was further reinforced by two testimonial letters from independent experts, who explicitly confirmed the long-term clinical significance of the client's future research plans.

Following a Premium Processing upgrade requested on April 6th, 2026, USCIS approved the I-140 NIW petition on May 29th, 2026. We are honored to have assisted our client in securing NIW approval and supporting his continued efforts to improve medication safety, patient outcomes, and evidence-based gastrointestinal care through data-driven medical research in the United States.
