Client’s Testimonial:

"Thank you to the attorney and the Chen Immigration team for their diligent work on my case. The I-140 petition, supporting letter, and recommendation letters were all exceptionally thorough and well-prepared.”

On March 20^th, 2026, we received another EB-1A (Alien of Extraordinary Ability) approval for a Manager Performance Analytics in the Field of Gastroenterology (Approval Notice).

General Field: Gastroenterology

Position at the Time of Case Filing: Manager Performance Analytics

Country of Origin: India

State of Residence at the Time of Filing: Texas

Approval Notice Date: March 20^th, 2026

Processing Time: 18 days (Premium Processing Requested)

Case Summary:

The client secured I-140 EB1A approval through direct Premium Processing in just 18 days. In the petition, we presented the client as an established expert in gastroenterology and a leading specialist in hepatopancreatobiliary surgery and oncology, with particularly notable work on the clinical and financial outcomes of open versus robotic pancreaticoduodenectomy. That focus helped show a clear area of extraordinary ability rather than a broad, generalized medical profile.

The client’s background also supported this positioning. With an MD and an MHA, the client built a profile that combines medical expertise with outcomes analysis and healthcare efficiency. The petition further showed that the client is continuing this work in a current performance analytics role involving clinical, operational, and financial data as well as outcomes research, which reinforced that the client’s achievements are ongoing and directly relevant to future work in the United States.

The evidentiary record was strong and focused:

● 16 peer-reviewed journal articles, including 1 first-authored article
● At least 10 completed peer reviews
● A citation record reflecting at least 124 citations in the documented materials
● 4 letters of recommendation

These metrics mattered because they showed more than productivity. The publication record demonstrated sustained output in demanding venues, the peer review service showed that journals trusted the client’s expertise, and the citation record indicated that other researchers were actively relying on the client’s findings in their own work. The petition also emphasized that the client’s research informed later studies on robotic liver surgery, acute pancreatitis management, and pancreatic surgery outcomes, helping demonstrate major significance in practical and adjudicator-friendly terms.
