Open-source plugin for U.S. EB-2 National Interest Waiver (NIW) case work. Honest pre-filing legal evaluation of self-petitions under the current USCIS adjudication standard, with the preponderance-of-the-evidence burden applied prong by prong under Matter of Dhanasar. Built for three cohorts: DIY self-petitioners ready to file, prospective applicants 6–24 months out, and master's/PhD students 3–5 years out who want a multi-year roadmap before committing. Key features: • Agentic 5-stage conversation — orient → co-design your proposed endeavor → confirm → full evaluation → follow-ups. Adapts to what you know and what you've provided; produces a clean structured memo, not an engineering trace. • Citation discipline — every legal rule cites authority inline (Dhanasar, Chawathe, Katigbak, USCIS Policy Manual Vol. 6 Pt. F Ch. 5, and curated AAO decisions). • Verdict floor under preponderance — no inflated assessments. No prong is rated "Strong" without documented evidence clearing preponderance. • Hard anti-hallucination rules — no invented citation counts, grant roles, employer facts, or AAO decision IDs. • Achievable case ceiling — beyond the current-state verdict, the plugin produces a roadmap of concrete prerequisite actions and an honest 0–60 month timeline to reach a stronger case. • AC21 framing for India/China nationals — surfaces the practical reason most backlogged-country petitioners file NIW: an approved I-140 unlocks indefinite H-1B extension under AC21 § 104(c) and § 106(a). • Written for international, ESL-primary, highly-educated users — short sentences, technical terms explained on first use, citations in standard form, no idioms.
