Green Card holders who need to spend extended time abroad face a complex web of rules around re-entry permits, tax filings, physical presence tracking, and document retention — with devastating consequences (losing permanent residency) if they get it wrong.
An app that tracks days spent outside the US, alerts users before critical thresholds (180 days, 1 year), generates checklists of required filings (I-131, taxes), helps maintain a digital evidence vault of US ties (bank statements, leases, utility bills), and provides a countdown to citizenship eligibility based on physical presence rules.
Freemium — free day-tracker, $9.99/mo for compliance alerts, document vault, citizenship timeline, and re-entry risk assessment
Losing a green card is catastrophic — years of waiting, tens of thousands in legal fees, potential deportation. The consequences of getting it wrong are life-altering and irreversible. People lose sleep over this. Reddit threads show genuine panic and confusion. This is a top-tier pain point with asymmetric downside.
~13M green card holders, but the addressable segment is those who travel internationally for extended periods — likely 10-20% (1.3M-2.6M). At $9.99/mo with even 1% penetration of the addressable market, that's $1.5M-$3M ARR. Solid niche SaaS but not a venture-scale market. Could expand to visa holders (H1B, L1) for a larger TAM.
People already pay $300-500/hr for immigration attorneys for basic consultations on this exact topic. $9.99/mo is trivial compared to the cost of getting it wrong (losing permanent residency). The pain signals show people actively seeking this information. However, some users may feel a spreadsheet is 'good enough' — the vault and alerts need to clearly justify the premium.
Core features are straightforward: date tracking, threshold math, push notifications, document upload/storage, checklist generation. No complex integrations needed for MVP. A solo dev can absolutely build this in 4-6 weeks. The rules engine (180 days, 1 year, citizenship eligibility) is well-documented. Cloud storage for documents is commodity. Mobile-first with a simple backend.
No single product combines all four pillars: (1) physical presence tracking, (2) compliance alerts with actionable checklists, (3) document evidence vault, (4) citizenship countdown. Existing tools are either too simple (just calculators), too expensive (attorney services), or built for lawyers (not consumers). The integrated compliance dashboard for individuals is a clear gap.
Natural subscription: compliance is ongoing (not a one-time event), document storage requires persistence, alerts need to be continuous, and the citizenship journey spans 3-5+ years. Users can't afford to churn — lapsing means losing their compliance safety net. High retention potential due to switching costs (uploaded documents, tracked history) and ongoing anxiety.
- +Extreme pain intensity with irreversible consequences — users are motivated by fear of losing permanent residency
- +No integrated competitor exists — the market has calculators OR attorney services, but nothing in between
- +Technically simple MVP with clear feature boundaries — can ship fast
- +Natural retention mechanics — ongoing compliance need, stored documents, multi-year citizenship timeline
- +Current political climate (2025-2026 enforcement escalation) creates urgency and willingness to pay
- !Legal liability — if the app gives incorrect thresholds or misses a rule change, users could rely on it and lose their green card. Need strong disclaimers and possibly attorney review of rules engine
- !Distribution challenge — reaching green card holders is niche. SEO for immigration terms is dominated by law firms with big ad budgets. May need community-driven growth (Reddit, diaspora forums, WhatsApp groups)
- !Users may resist uploading sensitive immigration documents to a startup's cloud — trust and security are table stakes
- !Rule changes under different administrations could require constant updates to the compliance engine
- !Free alternatives (spreadsheets, USCIS calculator) may be 'good enough' for price-sensitive users
Simple mobile apps that let green card holders log entry/exit dates and count days spent outside the US. Examples include 'GC Tracker' and 'Residency Tracker' on iOS/Android.
Free government tool that calculates whether you meet the physical presence requirement for naturalization based on trips entered manually.
Online immigration service that helps with green card applications, citizenship applications, and provides some educational content about maintaining status.
Practice management software for immigration attorneys to manage client cases, deadlines, and filings.
Tools like Australia's ImmiAccount or UK's visa tracking that help immigrants track status and compliance. In the US space, apps like 'Settle' and immigration chatbots have attempted similar consumer-facing tools.
Mobile app (React Native or Flutter) with: (1) Trip logger — enter departure/arrival dates, auto-calculate days outside US, (2) Dashboard showing days remaining before 180-day and 1-year thresholds with color-coded risk levels, (3) Push notification alerts at 150, 170, 180, 330, and 365 days, (4) Basic citizenship eligibility countdown based on physical presence rules, (5) Checklist generator for re-entry preparation (I-131, tax filing reminders). Skip the document vault for MVP — add it in v2 after validating demand.
