IMMIGRATION LAW · SONG LAW FIRM CASE STUDY
Client Profile
A Korean-American nursing professional in the 30s–40s range who has combined clinical practice, research, and teaching in the nursing field. Beyond clinical practice, the client had accumulated a track record of academic presentations, publications, professional society activity, cross-disciplinary collaborations, and invited lectures at domestic and international conferences. Motivated either by the burden of the H-1B cap or by difficulties encountered in prior firm proceedings, the client reconsidered O-1 status. This case study reflects the common pattern of cases in which, after a transfer from another firm, an O-1 approval was obtained at the RFE response stage.
Case Background
Nursing must be approached under the O-1A (sciences, education, business, athletics) category rather than the O-1B (arts) category, requiring the adjudicator to be persuaded that clinical nursing falls within "sciences" or "education" under O-1A. In cases where the category and criteria mapping had been unclear at the prior firm's stage, RFEs were often issued, and Song Law Firm reconstructed the case following transfer.
Legal Requirements
The legal basis for O-1A is INA § 101(a)(15)(O), with procedural regulations at 8 C.F.R. § 214.2(o). The evaluation standard requires that at least three of the eight categories of evidence enumerated at 8 C.F.R. § 214.2(o)(3)(iii) be satisfied.
Categories: nationally/internationally recognized prizes; membership requiring outstanding achievement; published material about the alien in professional media; judging others' work; original contributions of major significance; scholarly articles; employment in a critical or essential capacity; and high salary.
The RFE procedure follows 8 C.F.R. § 103.2(b)(8) and USCIS Policy Manual Volume 1, Part E.
Song Law Firm's Strategy
After the case transfer, Song Law Firm proceeded as follows.
First, review of the initial petition and RFE notice — we organized which categories the prior firm had attempted to map, and which issues had been raised in the RFE.
Second, nursing-field acclaim reframing — we prepared a brief explaining, on the basis of the USCIS Policy Manual and related provisions, that clinical nursing falls within "sciences" or "education" under O-1A.
Third, re-mapping of evidence across the eight categories:
(a) scholarly articles — nursing journal publications and clinical outcome research findings.
(b) published material about the alien — profiles and interviews in nursing trade press and industry media.
(c) judging others' work — conference abstract review, qualifying-examination review participation, and publication peer review.
(d) original contributions of major significance — development or improvement of clinical protocols and contributions to nursing education curricula.
(e) memberships requiring outstanding achievement — fellowship or full membership in prominent nursing societies.
(f) employment in critical/essential capacity — roles as lead nurse or specialty program director at hospitals or healthcare institutions.
(g) high salary — compensation level relative to industry benchmarks in the nursing field.
Fourth, expert opinion letters — from prominent nursing scholars and healthcare institution leaders, we obtained opinion letters supporting that the client's acclaim rose to sustained recognition in the clinical nursing field.
Fifth, RFE response brief — squarely addressing each issue raised by the adjudicator and explaining the standard for assessing acclaim in the nursing field as an industry standard.
Case Processing and Timeline
Following case transfer, review of the initial petition and RFE, re-mapping, expert-letter acquisition, and brief drafting took several weeks to several months. Supplemental evidence and the brief were submitted to USCIS ahead of the RFE response deadline.

Result
Following the RFE response, the client's O-1A petition received the final approval notice. The client sustained clinical, teaching, and research activity in the United States in O-1 status, and we followed up with consultation on green card path design.
Key Takeaways
Nursing must be approached under O-1A (sciences/education) rather than O-1B (arts), and a clear mapping across the eight categories and organization of field-specific acclaim indicators are essential. Even in RFE-issued cases, post-transfer reconstruction can lead to approval, and a brief that explains the field-specific evaluation standard to the adjudicator as an industry standard is decisive.
