GreenLight and Lawfully are both free USCIS case tracking tools, but they work differently. GreenLight is built for applicants who want privacy-first tracking: your receipt number stays on your device, while account sync is limited to the general case details needed for history and alerts. Lawfully connects to your USCIS account and offers a mobile app with AI-powered processing time predictions. This guide compares both tools honestly so you can decide which fits your situation.

Where GreenLight Wins
Privacy-first architecture
GreenLight keeps your receipt number in your browser and never sends it to GreenLight's servers. Common status messages decode locally. If the local decoder cannot recognize a message, the pasted text passes through GreenLight's decoder API for a fallback explanation; GreenLight does not log or store that text by default. General case details and statuses you intentionally save can sync after you create an account so history and alerts work.
Status decoder
GreenLight's decoder translates any USCIS status message into plain English, explaining what the update means, what typically comes next, and what (if anything) you should do. You can try it at greenlighttrack.com/decoder. Lawfully displays your status directly from USCIS but does not provide the same level of plain-language explanation.
Document checklists
GreenLight includes downloadable checklists for I-485 (adjustment of status), I-765 (work permit), and I-131 (travel document). Each checklist maps to the specific evidence requirements for that form. Lawfully's checklist functionality is more limited.
Where Lawfully Wins
Native mobile apps
Lawfully has dedicated iOS and Android apps with push notifications. If you prefer a native mobile experience over a web browser, Lawfully has the advantage here. GreenLight is a web-based application, though it is fully optimized for mobile browsers.
AI processing time predictions
Lawfully advertises historical-data-based processing predictions. GreenLight does not generate individual predictions; Community Pulse shows limited recent anonymous activity and keeps official or third-party reference figures labelled separately.
Which Should You Choose?
If privacy is your top priority, or you don't want to link your USCIS account to a third-party service, GreenLight is the better choice. If you want a native mobile app and AI-powered processing predictions, Lawfully has those features.
Many applicants use both: GreenLight for the status decoder and community timeline, Lawfully for mobile push notifications. Both are free at the base level.
Frequently Asked Questions
Is GreenLight free?Yes. GreenLight's core features include the status decoder, timeline visualization, Community Pulse, and checklists. Community Pulse shows limited recent anonymous activity rather than an individual prediction. Paid plans add features described on the current upgrade screen.
Does GreenLight store my receipt number?No. GreenLight does not store your receipt number on any server. Common decoder results are handled locally, and fallback decoder requests are not logged by default. If you create an account, the general case details you save can sync securely for history and alerts, but your receipt number remains local-only.
Which is better: GreenLight or Lawfully?It depends on your priorities. GreenLight focuses on a receipt-number-free status decoder, local case tracking, and limited anonymous community activity. Lawfully may fit people who want a native mobile app or its advertised prediction features. Verify each product's current features and privacy terms before choosing.
