Client’s Testimonial:
“Thank you very much for all your support. I really appreciate your firm’s clear guidance on timing and preparation throughout the process.”
On January 7th, 2026, we received another EB-2 NIW (National Interest Waiver) approval for a Postdoctoral Research Fellow in the field of Congenital Heart Surgery (Approval Notice).
General Field: Congenital Heart Surgery
Position at the Time of Case Filing: Postdoctoral Research Fellow
Country of Origin: South Korea
State of Residence at the Time of Filing: Texas
Approval Notice Date: January 7th, 2026
Processing Time: 2 months, 21 days (Premium Processing Requested)
Case Summary:
This NIW case succeeded because the record showed a compelling practical reality: the client’s research targets the exact critical constraints that determine whether children with severe heart disease can survive long enough to receive definitive care, and whether scarce donor hearts can be used effectively once they become available.
The client was a congenital heart surgery researcher from South Korea at the time of filing. North America Immigration Law Group (Chen Immigration Law Associates) presented the case around a single, cohesive theme: pediatric heart failure is a time-sensitive clinical problem, and the client’s work develops surgical strategies and pediatric-specific technologies that expand treatment options when time, size, and donor supply are all limiting factors.
External validation that the work is needed and credible
The petition demonstrated that the proposed endeavor is not just worthwhile, but already recognized as vital by outside decision-makers. Here, the record highlighted that the client’s research direction had attracted funding support from an external research grant source, reinforcing that the work has been competitively evaluated and aligned with urgent healthcare needs.
A track record that supports a forward-looking plan
To show the client was well-positioned, the petition paired medical training with documented research productivity.
The client holds an M.D. and has produced:
- 6 peer-reviewed journal articles (3 first-authored), 9 conference abstracts (5 first-authored), 2 book chapters (1 first-authored), and 2 additional accepted book chapters
- 36 total citations
Expert perspective on national relevance
NAILG also used expert letters to translate technical contributions into tangible clinical value. One testimonial captured the case’s central point in plain terms:
“Undoubtedly, [Client]’s research addresses critical needs in pediatric cardiac surgery, and his expertise aligns with U.S. healthcare goals to improve outcomes for children with life-threatening heart conditions.”
The outcome
USCIS approved the NIW petition on January 7th, 2026, in 2 months and 21 days under Premium Processing. We are honored to have supported the client and to have helped present a clear case that pediatric heart failure innovation is both nationally important and effectively advanced by a researcher with demonstrated output and a realistic pathway to continued impact.
