Upload your USCIS RFE PDF, get a plain-English breakdown of every officer concern + a structured first-draft response with evidence checklist — in 10 minutes, for $39 instead of $1500.

What we ship

**Core features (MVP)**

• Drag-and-drop USCIS RFE PDF upload — parses in 60 seconds, auto-detects form type (I-129 / I-140 / I-485).
• Plain-English breakdown of every officer concern: what's being asked, why, what evidence is expected.
• Structured first-draft response: cover letter + per-issue sections + evidence checklist grounded in USCIS policy memos and AAO precedent.
• DOCX/PDF download of the finished draft with mandatory "educational reference only — not legal advice" disclaimer block.
• Premium tier ($79): 1 follow-up clarifying question + handoff to attorney-review marketplace.

**Primary user flow**

1. Applicant finds us via SEO ("h1b rfe specialty occupation response example") or Reddit r/h1b.

2. Landing page CTA "Upload your RFE PDF" — no signup until payment.

3. Uploads RFE → sees free preview of the first issue decoded → pays $39 via Stripe Checkout → unlocks full draft + checklist.

4. Downloads DOCX, fills personal details, files with USCIS. Premium upsell ($79) triggers: "need a second question answered or attorney sanity-check?".

**What it looks like**

• **Landing page**: hero "Got an RFE? Decode it and draft your response in 10 minutes — for $39, not $1500." Below hero: 3-step skeleton (Upload → Decode → Draft) + before/after example. CTA: "Upload your RFE — free preview".
• **Main app screen**: split-pane. Left: original RFE PDF with officer-issues highlighted. Right: "Your draft response" — collapsible sections per issue, evidence-checklist with checkboxes, citations to USCIS memos. Top-right "Download DOCX" button (locked until payment).
• **Output**: DOCX file — title page with case number, cover letter, response sections, evidence list, disclaimer footer on every page. Plus email with a 30-day re-download link.

**MVP build plan (10 days)**

• Day 1-3: FastAPI + Postgres on Railway, R2 for PDFs, Stripe Checkout one-time $39/$79, email-magic-link JWT.
• Day 4-7: Claude Sonnet 4.6 prompt pipeline (RFE parse → issue extraction → draft generation), preload USCIS policy memos + AAO precedent corpus into Postgres.

• Day 11: 10 SEO long-tail pages, Reddit launch threads, telemetry.

Source signals

• `SIG-20260425-us-ai-wrapper-vertical-uscis-rfe-responder` — "RFE Decoder built in a week, taking real $27 Stripe payments by end of day, two autonomous content agents on schedule"
• `SIG-20260425-us-ai-wrapper-vertical-medical-bill-decoder` — "Up to 60% of medical bills contain errors. Real user pain isn't translation — it's 'what should I do next?'" (parallel pattern: regulated-doc explainer + actionable next step)
• `SIG-20260425-us-ai-wrapper-vertical-execute-not-just-report` — "If a tool just says 'rewrite your H1 tags', I'm out. If it executes, I'm paying" (categorical: must produce draft, not just analysis)

Reasoning

The SIG-uscis-rfe-responder signal showed a solo founder built RFE Decoder in a week and was already taking real $27 Stripe payments on launch day. That's a strong day-1 willingness-to-pay signal in a niche where the alternative is a $500-2000 immigration attorney.

The adjacent SIG-medical-bill-decoder confirms a categorical pattern: **regulated-document explainer + actionable next step** works (HIPAA-compliance, US healthcare-billing schema knowledge, action layer beating raw ChatGPT). Same playbook applies here: USCIS-RFE schema, immigration-law citations, draft-response-as-action.

Quick competitive read shows: **Parley.so** ($299+/mo, attorney-only), **Imagility/Visalaw.ai/Visas.ai** — all target law firms. **USVisaStack** offers a free outline-only generator without draft or evidence-mapping. Direct-to-applicant tier at $27-79 per RFE is essentially white-space.

Stack-fit is ideal: one document type (USCIS RFE PDF), one workflow (parse → explain → draft + evidence checklist), one segment (US applicants without in-house attorney), textbook ai-wrapper-vertical in FastAPI + Postgres + Stripe Checkout. 10-day build window.

Regulatory risk: **not legal advice**. "Educational reference only, not legal advice" disclaimer is mandatory (USVisaStack does the same). This positions the product as a consumer tool, not legaltech — removes most compliance burden.

Quick competitive read

• **Parley.so** (CMP-IDEA-005-parley-so): attorney-targeted Word add-in + RFE Analyzer, contact-for-pricing (firm subscription, est. $1K-10K+/mo). SOC 2 Type II + GDPR. Featured in Business Insider April 2025. Doesn't compete for the applicant segment.
• **LegistAI** (CMP-IDEA-005-legistai): AI-native immigration law platform with workflow-driven RFE response automation, contact-for-pricing. Full case-management for law firms.
• **RFE Studio / uscisrealtime.com** (CMP-IDEA-005-rfe-studio): specialized in EB-2 NIW + EB-1A self-petitioners, evidence-grounded generation. Solo builder, 2025 launch. Doesn't cover H-1B / F-1 OPT / I-485 RFEs (>70% of all RFEs).
• **USVisaStack RFE Generator** (CMP-IDEA-005-usvisastack): free outline tool, lead-gen for paid attorney services. Validates SEO channel for applicant tier.
• **Visalaw.ai** (CMP-IDEA-005-visalaw-ai): generalist immigration AI for attorneys (research + drafting + translation + Exhibit List Review). Subscription with draft limits.

**Market density: medium** (4-5 attorney-tier incumbents + 1 outline-only consumer tool). **White-space confirmed**: direct-to-applicant, full-draft + evidence-checklist tier at $39/RFE — every named incumbent either targets attorneys at $69-200+/seat/mo or strips down to outline-only freebies. The completion-tier consumer slot is open.

Initial pricing hypothesis

$39 per RFE (Standard) + $79 Premium (includes 1 follow-up question + attorney-review marketplace handoff). Pay-per-use, not subscription — closes the SIG-pdf-pay-per-use pattern (subscription fatigue for episodic AI use). Adjacent business model: subscription for immigration consultants and paralegals at $99/mo for 5 RFEs/month.

Distribution hypothesis

1) **SEO + programmatic content**: pages targeting long-tail "h1b rfe specialty occupation response example", "f1 opt rfe response template" — USVisaStack runs this playbook successfully.

2) **Reddit organic**: r/immigration, r/h1b, r/USCIS — real RFE questions every day (RFE Decoder is already scraping these sources for content engine).

3) **TikTok / YouTube Shorts**: immigration creators (Rajiv Khanna, Boundless) have huge engaged audiences.

4) **Affiliate with paralegals and immigration consultants** ($10-15 commission per RFE).
