Case Summary:  

We are pleased to share the success story of an I-140 EB-1B (Outstanding Professor or Researcher) approval completed in 18 days, filed with Premium Processing immediately upon submission. The client is a mathematician with a Ph.D. and A.M. in Mathematics, and the petition focused on presenting a clear record of original contributions and recognition within the field.

Research Focus and Contributions:

The client’s specialized research focuses on harmonic analysis and operator theory in generalized mathematical spaces. In the petition, we explained how this kind of foundational work supports the broader understanding of complex mathematical systems that underpin advanced technologies across engineering, medical imaging, and computational sciences. We also highlighted the client’s strong background across multiple subfields of analysis, positioning the client as someone capable of producing original results with meaningful downstream relevance, including improved signal processing approaches, stronger mathematical foundations for diagnostic tools, and more efficient methods for high-dimensional data analysis.

A central example of the client’s impact is pioneering work on Cauchy integral commutator operator boundedness, where the client established principles that help researchers understand operator behavior across diverse analytical frameworks. Rather than presenting this as abstract theory alone, we framed it as advancing the field because it provides tools that other experts can build on when studying complex operators in modern analysis.

At the time of filing, the client had produced 7 peer-reviewed journal articles and 4 preprints, including one first-authored preprint, and the work had been cited 95 times. We did not treat these metrics as automatically sufficient. Instead, we explained how an adjudicator could reasonably interpret the publication and citation record as objective evidence that independent researchers are reading, using, and referencing the client’s findings, which is especially persuasive in a theoretical discipline where influence is often reflected through citation by other specialists.

The petition also documented that the client completed at least 14 peer reviews. We positioned this as a form of professional recognition, showing that journals trusted the client to evaluate the work of other researchers, which supports the conclusion that the client is regarded as a knowledgeable expert in the field.

To further reinforce the significance of the client’s work, we included evidence of major research funding sources associated with the client’s research environment and collaborations, including major international funding bodies such as the ERC, NSF, Ikerbasque, ARC, NSFC, and NSERC. We used this to show that the client’s area of work aligns with research priorities that receive competitive support from well-regarded funding bodies.

The client is currently employed in a tenure-track assistant professor role at a U.S. university, where the role includes conducting research in harmonic analysis and related areas. This helped demonstrate that the client is well-positioned to continue producing influential scholarship in the United States.

Support from Experts in the Field:

To strengthen the record of recognition, the petition included 6 letters of recommendation from established experts in mathematics. These letters served to clarify the importance of the client’s contributions in adjudicator-friendly terms by explaining what the client did, why it was technically meaningful, and how it has influenced or supported ongoing work by other researchers. We used the letters to corroborate, not replace, the objective evidence from publications, citations, peer-review activity, and funding context.

 “It is clear, then, that [Client’s] work has had a profound impact on harmonic analysis, and therefore on mathematics as a whole. She has advanced the current state of knowledge in harmonic analysis, and her work is being implemented by other researchers as well. She is therefore an extremely important mathematician who must be allowed to continue her work for the benefit of mathematics and beyond.”

EB-1B Approval and Outlook:

By presenting the evidence as a cohesive narrative of original contributions, sustained scholarly output, independent recognition through citations and peer review, and strong expert support, we demonstrated that the client meets the EB-1B standard. USCIS approved the I-140 through Premium Processing in just 18 days. We are proud to have guided this mathematician to approval and look forward to the client’s continued contributions to mathematical research that supports innovation across multiple advanced technical domains in the United States.
