Case Summary:  

North America Immigration Law Group (Chen Immigration Law Associates) is pleased to share an I-140 EB-1A (Alien of Extraordinary Ability) approval for the client, a virology specialist whose work strengthens how the field studies, tracks, and counteracts high-consequence pathogens. With a focus spanning vaccinology, reverse genetics, genome sequencing, and phylogenetic analysis, the client is especially well known for investigations into the cross-species transmission mode of highly pathogenic avian influenza H5N1.

Research Focus
With a Ph.D. in Infection Biology, the client has developed a specialized profile in virology with practical relevance to surveillance and outbreak response. The petition emphasized a cohesive research direction centered on two connected goals: improving how the scientific community characterizes transmission and evolution of dangerous viruses, and translating that understanding into platforms that support prevention and control, including vaccine-related approaches.

Rather than presenting isolated publications, we framed the client’s work as a sustained effort to advance the tools and reasoning the field uses when high-risk pathogens emerge, particularly in the context of cross-species dynamics where early detection, tracking, and interpretation can determine whether response efforts succeed.

An Evidentiary Record
For EB-1A, strong numbers help, but they are not automatically decisive. The key is showing that the record reflects recognized, field-wide influence rather than routine academic productivity. We organized the petition to emphasize independent reliance and professional trust, using objective indicators that an adjudicator can verify.

The petition highlighted the client’s publication and impact record:
– 74 peer-reviewed journal articles (including 15 first-authored and co-first-authored)
– 4 preprints (including 2 first-authored)
– 1,777 citations

We did not treat citations as self-proving. Instead, we positioned them as evidence that other researchers repeatedly used the client’s findings and methods as inputs for their own work, which is a key way adjudicators can distinguish field-recognized contributions from routine participation.

Peer-Recognized Authority
Another central signal of extraordinary ability is whether the field repeatedly entrusts the researcher with evaluative responsibilities. The record showed that the client has conducted at least 40 peer reviews. Because journals typically invite reviewers who are regarded as technically qualified and reliable, we presented this activity as evidence of sustained professional trust in the client’s judgment.

The petition also included evidence that the client’s work has attracted support from major U.S. research sponsors and agencies and a state-level agriculture and markets department. We used this funding history as corroborating context that the client’s research direction aligns with important U.S. public and animal health priorities and has earned confidence from selective funding mechanisms.

Expert Recommendation Letters
To strengthen the case record and connect the objective metrics to real-world significance, the petition included four recommendation letters from established experts. One recommender noted:

“For public health and agricultural biosecurity applications, it is imperative that the country support his work.”

The Result
The EB-1A I-140 petition was approved after receiving a NOID, reflecting that the case presentation successfully framed the client’s achievements as sustained, field-recognized impact in virology, supported by a documented publication record, substantial independent citations, extensive peer-review service, major research support, and expert testimony.
