Your case. Your data.

A few useful answers.
Is this an official USCIS service?
No. CaseStatusTracker is independent and is not affiliated with USCIS or the U.S. government. Check official USCIS notices and tools for case decisions.
Can this tell me when my case will be approved?
No. Event codes and timestamps cannot establish an approval date, approval probability, or internal processing stage.
What does a silent update mean here?
It means a record update timestamp is later than the latest reliable event timestamp in the data you supplied. The difference alone does not explain why a record changed.
Do I need to pay or sign in?
No. Reading JSON, viewing the timeline, and checking timestamp differences are free and available without registration.
