RE: Immigrant Petition for Alien Worker (Form I-140)

Petitioner / Beneficiary: Mr. L (self-petition — petitioner and beneficiary are the same person)

Classification Sought: Alien of Extraordinary Ability, INA § 203(b)(1)(A); 8 CFR 204.5(h)

Field of Extraordinary Ability: Real-time machine-learning fraud detection for cross-border payments

Criteria Claimed: 8 CFR 204.5(h)(3)(v) — original contributions of major significance; (viii) — leading or critical role; (iv) — judging the work of others

This petition is respectfully submitted by Mr. L, founder and chief architect of a U.S. financial-technology company whose systems screen cross-border payments for fraud in real time. Mr. L's field of endeavor is real-time machine-learning fraud detection for cross-border payments — a defined technical sub-discipline at the intersection of payments infrastructure and applied machine learning. It is not "finance," "software engineering," or "fintech" generally; it is the specific discipline of building models and decision systems that approve or block international payment transactions in under a second.

As detailed below and supported by Exhibits 1–33, Mr. L satisfies three of the ten regulatory criteria at 8 CFR 204.5(h)(3): original contributions of major significance to the field (§ 204.5(h)(3)(v)), a leading and critical role for organizations with a distinguished reputation (§ 204.5(h)(3)(viii)), and participation as a judge of the work of others in the field (§ 204.5(h)(3)(iv)). Considered in its totality, the record demonstrates sustained international acclaim and places Mr. L among the small percentage at the very top of his field.

Under 8 CFR 204.5(h)(2), "extraordinary ability" means "a level of expertise indicating that the individual is one of that small percentage who have risen to the very top of the field of endeavor." Absent a one-time achievement in the form of a major, internationally recognized award, the petitioner must submit evidence satisfying at least three of the ten criteria at 8 CFR 204.5(h)(3). Under Kazarian v. USCIS, 596 F.3d 1115 (9th Cir. 2010), adjudication proceeds in two steps: first, a count of whether the evidence meets at least three regulatory criteria; second, a final merits determination of whether the totality of the evidence demonstrates sustained national or international acclaim and standing among the small percentage at the top of the field. The applicable standard of proof is the preponderance of the evidence — "more likely than not" — Matter of Chawathe, 25 I&N Dec. 369, 375–76 (AAO 2010).

Mr. L developed the graph-based transaction-linking method that his company deployed in production in 2021 (Exhibit 12, peer-reviewed paper describing the method; Exhibit 13, granted U.S. patent). The contribution is original: before Mr. L's work, cross-border fraud screening relied on per-transaction rule engines that could not detect coordinated fraud rings operating across corridors, as documented in the pre-2021 industry literature (Exhibit 14).

Its significance is major and extends across the field, not merely within Mr. L's company. Three payment networks with no corporate affiliation to Mr. L have licensed or independently implemented the method, together screening over $40 billion in annual cross-border volume (Exhibits 15–17, signed adoption letters from each network's head of risk). An independent industry analysis names the method one of the five techniques that "changed the default architecture of cross-border fraud screening" (Exhibit 18). Dr. M., professor of computer science at a U.S. research university who has never worked with or co-published with Mr. L, writes that the method "resolved a failure mode the field had documented for a decade but not solved" (Exhibit 19).

Mr. L performs a critical role for his company as founder and chief architect. He designed, and retains final technical authority over, the fraud-decision engine through which every transaction the company screens must pass; the chief executive officer's letter explains that "no scoring model reaches production without Mr. L's sign-off, and the decision engine is the product" (Exhibit 21; Exhibit 22, organizational chart showing Mr. L reporting directly to the board).

The organization holds a distinguished reputation in the field. It screens payments in four of the twenty largest cross-border remittance corridors (Exhibit 23, corridor coverage report), was named to a major financial publication's annual list of leading payments-infrastructure companies in 2024 and 2025 (Exhibit 24), and has raised $85 million from institutional investors whose diligence reports are excerpted at Exhibit 25. Trade-press coverage of the company's fraud-screening results appears at Exhibit 26.

Mr. L has repeatedly served as a judge of the work of others in his field. He has completed peer review of eleven manuscripts for a leading journal of payments risk and financial-crime technology between 2022 and 2025 (Exhibit 27, editor invitations and completed-review confirmations). He served on the judging panel of an international fintech industry awards program in 2024 (Exhibit 28, organizer's letter describing selection criteria for judges), and on the program committee of a peer-reviewed conference on fraud and financial crime (Exhibit 29). The journal editor's invitation states that reviewers are selected "on the basis of demonstrated expertise in the manuscript's sub-field" (Exhibit 27).

Considered in its totality, the record establishes that Mr. L has sustained international acclaim and stands among the small percentage at the very top of the field of real-time fraud detection for cross-border payments. The evidence is not a set of isolated data points; it tells one consistent story. Mr. L created a method the field itself adopted as a new default (Exhibits 12–19); he holds final technical authority at one of the organizations defining that field's practice (Exhibits 21–26); and the field repeatedly turns to him to judge the work of its other members (Exhibits 27–29). Each fact reinforces the others: networks adopted the method because of its demonstrated significance; the judging invitations cite the expertise demonstrated by that same body of work.

The acclaim is sustained, not episodic: the record spans 2019 through 2026 without interruption — publication and patent (2019–2021), field-wide adoption (2021–2024), judging service and industry recognition (2022–2026). On the preponderance standard, the totality of this record places Mr. L within the small percentage at the very top of his field.

Mr. L will continue to work in his area of extraordinary ability in the United States. His company's U.S. expansion roadmap (Exhibit 31) and a signed term sheet for its next financing round (Exhibit 32) commit the company's fraud-detection engineering organization to U.S. operations through at least 2029, and Mr. L's signed statement of plans (Exhibit 33) details the next generation of cross-corridor fraud models he will build. His continued work substantially benefits the United States: cross-border payment fraud produced documented multi-billion-dollar U.S. losses in 2025 alone (Exhibit 30, federal consumer-protection fraud-loss data), and the corridors his systems screen include the highest-volume U.S. remittance routes.

For the foregoing reasons, Mr. L respectfully submits that he qualifies for classification as an alien of extraordinary ability under INA § 203(b)(1)(A) and requests that this petition be approved.
