Applicants don't know what evidence is 'more than enough' and stress over whether their package will convince the officer. Disorganized or insufficient evidence leads to RFEs or denials.
Step-by-step wizard that helps couples compile, organize, and score their evidence package (joint finances, photos, affidavits, etc.) against known approval benchmarks. Includes mock interview Q&A based on real officer patterns by field office.
One-time purchase ($49-149) or freemium with paid 'interview readiness score' and evidence gap analysis.
This is a 9/10 pain. Marriage green card applicants experience extreme anxiety — a denial or RFE can mean family separation, deportation risk, or months of additional waiting. The Reddit post you cited (187 upvotes, 123 comments) shows people celebrating approvals like life-changing events. Couples lose sleep over whether their evidence is 'enough.' The stakes are existential: your right to live with your spouse in the country. Few consumer problems have this level of emotional intensity.
~300K I-485 marriage-based filings/year in the US. If 30-40% self-file (conservative), that's 90-120K potential customers/year. At $49-149 per customer, that's a $4.4M-$17.9M/year addressable market for the self-filing segment alone. Add attorney-represented couples who want supplemental interview prep, and you get another chunk. Not a billion-dollar TAM, but a very healthy niche SaaS business. The ceiling is real though — this is a one-time purchase for most people, and the market doesn't grow 10x.
Extremely high willingness to pay relative to the price point. Couples already pay $1,225 in USCIS filing fees, $500-5000 for lawyers, $300+ for medical exams, and $200+ for document translation. A $49-149 tool is trivial in this context. The comparison anchor is a $2000+ lawyer, not a $10/month SaaS. When the alternative is an RFE that delays your case by 6-12 months or a denial that costs $1,225 to refile, $149 is a no-brainer. Immigration is one of the few spaces where people willingly pay for peace of mind.
Core MVP is very buildable by a solo dev in 4-8 weeks. The evidence wizard is essentially a structured questionnaire with scoring logic. The interview Q&A can be seeded from publicly available interview reports on VisaJourney/Reddit and enhanced with LLM generation. No complex integrations needed. The AI scoring is the differentiator but doesn't need to be perfect at launch — even a basic weighted checklist would outperform what exists. Main technical risk: keeping up with USCIS policy changes requires ongoing content maintenance, not just engineering.
This is a genuine gap. Existing players fall into two buckets: (1) form-filling tools that stop before evidence strategy, and (2) expensive attorneys who gatekeep their knowledge. NOBODY is doing AI-powered evidence scoring, evidence gap analysis, or field-office-specific mock interviews as a standalone product. The forums have the raw data but in completely unstructured form. You'd be productizing the tribal knowledge that currently only exists in Reddit threads and attorney experience. First mover advantage is real here.
This is the biggest weakness. Green card is a one-time life event for most people. You use the tool once, get approved, and never come back. No natural recurring revenue. You could stretch into: (1) citizenship prep 3-5 years later, (2) upselling to other immigration filings (work permits, travel documents), (3) referral incentives, or (4) a subscription for ongoing case tracking during the 6-18 month waiting period. But fundamentally this is a one-time purchase business, not a SaaS. You need a continuous pipeline of new customers, not retention.
- +Extreme pain intensity — applicants will pay almost anything to reduce risk of denial or family separation
- +Clear competition gap — nobody is doing evidence scoring or AI interview prep in a standalone product
- +High willingness to pay relative to price point ($149 vs $2000+ attorney alternative)
- +Strong SEO/content marketing opportunity — immigration keywords have high search volume and desperate searchers
- +Built-in viral loop — approved couples eagerly share what worked in Reddit/Facebook immigration groups
- +Low technical risk — MVP is a structured wizard + LLM, not a moonshot engineering problem
- !One-time purchase model means you need constant customer acquisition — no recurring revenue flywheel
- !UPL (Unauthorized Practice of Law) risk — you must be extremely careful not to provide 'legal advice,' only 'information organization.' One cease-and-desist from a state bar could be existential. Need clear disclaimers and possibly attorney review of the product
- !USCIS policy changes, form updates, and field office pattern shifts require ongoing content maintenance — this is an operational burden, not just a build-once product
- !Immigration is an emotional, high-stakes domain — one highly visible bad outcome blamed on your tool could destroy trust and invite regulatory scrutiny
- !The most anxious customers (your best market) may still hire lawyers anyway for the psychological safety, using your tool as a supplement rather than replacement

Week 1-2: Build the evidence package wizard — a step-by-step questionnaire covering the ~12 evidence categories (joint finances, shared address, photos, affidavits, communication logs, etc.). Output a scored 'evidence strength report' showing green/yellow/red per category with specific suggestions to fill gaps. Week 3-4: Add the mock interview module — 50-100 common officer questions organized by topic, with AI-generated follow-up questions based on the couple's specific profile (how they met, timeline, living situation). Week 5-6: Add field office intelligence for the top 10 busiest offices (NYC, LA, Houston, Chicago, etc.) showing interview likelihood, common officer focus areas, and wait times. Ship with a simple Stripe checkout, no free tier — charge $49 for evidence scoring only, $99 for evidence + interview prep, $149 for the full package with field office intelligence.
Launch at $49-149 one-time purchase with three tiers. Free lead magnet: a basic 'evidence checklist' PDF that captures emails. Once you have volume, add: (1) $29 'evidence review update' when couples want to refresh their package before the interview, (2) $199 premium tier with AI-generated cover letter and evidence index, (3) affiliate partnerships with immigration attorneys for complex cases you can't serve, (4) B2B play selling the tool to immigration law firms as a client intake/evidence gathering platform ($99/month per seat). The B2B pivot is where recurring revenue lives.
4-6 weeks to MVP, first revenue within 1-2 weeks of launch. Immigration Reddit communities and Facebook groups are incredibly receptive to tools that help — a well-crafted launch post in r/USCIS, r/immigration, or r/greencard showing a real evidence scoring example could drive 50-200 purchases in the first week. Content marketing (blog posts targeting 'marriage green card evidence checklist,' 'I-130/I-485 interview questions') will build organic traffic within 2-3 months. Expect $5K-15K/month within 3 months if execution is solid.
- “I gave more than enough evidence and it's really obvious that everything is real”
- “Detailed timeline tracking suggests high anxiety about each case milestone”
- “I just forgot to ask about my SSN — confusion about what to do/ask at each stage”
