Terms of Use
Last updated October 5, 2026
Community availability information
SlotSignal displays user-submitted observations about U.S. visa appointment calendars. Reports can be delayed, incomplete, or inaccurate. A report is not an available appointment or a promise that a date can be booked. Confirm all details on the official appointment service.
Your application and account
You control your visa account and appointment decisions. SlotSignal does not sign in to the official portal, book, cancel, reschedule, or hold appointments for you. Keep your account credentials private and do not submit them to SlotSignal.
Browser extension
The extension's calendar scan runs only after you press its scan button on a supported portal page. It reads date information from visible calendar cells to fill a proposed report. It does not submit a report until you review it and confirm sharing.
Acceptable use and availability
Use SlotSignal lawfully and do not interfere with the service or submit knowingly false reports. Pilot features may change or be unavailable. SlotSignal is an independent community project and is not affiliated with the U.S. Department of State, an embassy, or the appointment portal operator.
