Green Card holders can lose their status if they stay outside the U.S. too long (6+ months continuous or 1+ year), but there's no easy way to track cumulative absences across multiple trips over years.
Logs trips automatically (manual or calendar/airline email integration), calculates rolling absence totals, warns at configurable thresholds (90, 150, 180 days), and generates a travel history report useful for N-400 naturalization applications.
Freemium — free basic tracking for up to 5 trips, $3.99/mo for unlimited trips, N-400 travel history export, and re-entry permit reminders
The pain is real but episodic — it spikes when someone is planning a long trip, returning to the U.S. after extended absence, or starting their N-400 application. The consequence (losing green card) is catastrophic, which amplifies urgency, but most LPRs don't think about it daily. The Reddit thread shows genuine anxiety. However, many people coast with spreadsheets or just don't travel enough to care.
TAM: ~13M LPRs × maybe 15-20% travel frequently enough to worry = ~2-2.5M potential users. Realistically serviceable market is narrower — those who travel 2+ international trips/year AND are aware of the risk. At $3.99/mo, even 10K paying subscribers = ~$480K ARR. Decent for a solo business but this is a niche within a niche. The N-400 export feature expands TAM to anyone approaching citizenship (~900K/year applicants).
This is the weak link. The core tracker competes with free spreadsheets and the 'I'll just remember' mindset. Immigration is a space where people pay lawyers ($2K-$10K) but resist paying for software tools. $3.99/mo may feel expensive for what seems like a simple calendar. The N-400 export and re-entry permit reminders add value but may not justify ongoing subscription. One-time purchase ($9.99-$19.99) for N-400 export may convert better than monthly subscription.
Very buildable MVP in 4-6 weeks for a solo dev. Core is just date math + CRUD for trips + threshold alerts. Calendar integration and airline email parsing add complexity but can be Phase 2. No AI needed, no complex infrastructure. A React Native or Flutter app + simple backend (or even local-first with cloud sync) handles it. The immigration rules (180-day, 1-year, physical presence for N-400) are well-documented and deterministic.
Surprisingly wide gap. No one owns this specific problem with a dedicated, well-designed product. CitizenPath is a calculator not a tracker. Lawfully focuses on case status. USCIS tools are primitive. The dedicated absence-tracking-with-alerts product basically does not exist. First mover with a polished mobile app and smart alerts could own this niche quickly.
Weak recurring justification. Once trips are logged, the app is passive — users check it a few times a year. Hard to justify monthly subscription for something used sporadically. Better model might be: free tracker forever (land grab) → paid N-400 export ($19.99 one-time) → premium annual plan ($24.99/year) for alerts, re-entry permit tracking, and attorney consultation credits. Pure monthly SaaS is a tough sell here.
- +Clear competition gap — no dedicated product owns this specific problem despite millions of potential users
- +Catastrophic downside (losing green card) creates emotional urgency that drives adoption
- +Technically simple MVP with well-defined, deterministic rules — low engineering risk
- +Natural viral loop: immigration communities on Reddit, WhatsApp groups, and Facebook groups are highly active and share tools
- +Built-in expansion path to N-400 citizenship prep (larger market, higher willingness to pay)
- !Monetization is the biggest risk — the core product (trip logging + date math) feels like it should be free, and competing with spreadsheets on price is a race to zero
- !Low engagement frequency (check app a few times per year) makes retention metrics look bad and subscription hard to justify
- !Immigration policy changes could shift the rules overnight (e.g., if USCIS builds a better tool or relaxes absence rules)
- !User acquisition cost in a niche market — reaching green card holders specifically is harder than it sounds, and immigration keywords are expensive ($15-40 CPC)
- !Trust barrier — users may hesitate to log sensitive immigration travel data in a third-party app from an unknown developer
Online tool from CitizenPath that helps green card holders log trips and calculate days outside the U.S. for N-400 purposes. Part of their broader immigration self-filing platform.
Full-service immigration platform that includes a travel history tool as part of N-400 citizenship application prep. Pairs applicants with attorneys.
Official USCIS website offers an eligibility calculator and case tracker. Includes a basic physical presence calculator for naturalization.
Google Sheets and Excel templates shared in immigration forums and Reddit for manually logging trips and calculating absence days. Most common 'tool' people actually use.
Mobile apps focused on tracking USCIS case status
Mobile app (iOS first — higher-income immigrant demographic) with: manual trip entry (departure/return dates + country), rolling absence calculator showing days outside U.S. in last 1 year and 5 years, color-coded warning thresholds (green/yellow/red at 150/180/365 days), push notification alerts when approaching thresholds, and a clean PDF export of travel history formatted for N-400 Part 8. Skip calendar/email integration for MVP. Add a simple onboarding that explains the legal thresholds in plain English. Include a disclaimer that it's not legal advice.
Free tier (unlimited trip logging + basic alerts — maximize adoption and word-of-mouth) → Paid one-time purchase ($14.99) for N-400 travel history PDF/CSV export when user starts citizenship process → Premium annual plan ($29.99/year) for re-entry permit reminders, shared family tracking, attorney consultation marketplace, and priority support → B2B play: license to immigration law firms as a client management tool ($99/firm/month)
8-12 weeks to first dollar. ~4-6 weeks to build and ship MVP, ~2-4 weeks for initial organic traction via Reddit/immigration forums and App Store optimization. First revenue likely from N-400 export purchases rather than subscriptions. Expect slow ramp — this is a word-of-mouth niche, not a viral consumer app. Realistic target: 500 free users and $500-1000 MRR within 6 months.
