Available locations and alert options vary by country, visa category, and appointment type. Use the options available for your registration. Updates come from community reports. Check the displayed timestamps: this is not a continuous feed from the official booking system. Reports can become outdated before you sign in to book. ACCESS AND ALERT ELIGIBILITY Sign in with the access code from your CheckVisaSlots registration. Availability access is subject to usage limits. Personalized alerts require an active alert plan; paid plans and eligible trials have their own access conditions. Alerts depend on matching preferences, reported availability, and account eligibility. Limited-slot alerts can depend on recent contributions and contributor rank. Qualifying bulk alerts may be sent without recent contributions. Eligible trials may have limited alert coverage. Contribute availability reports through a supported CheckVisaSlots browser extension while checking the official visa portal. Use the same registered account. The app's Alerts section shows your preferences, history, and rank. Enable notifications on your eligible device for mobile alerts. BEFORE YOU BOOK A report or alert does not reserve an appointment or guarantee that a slot remains available. Confirm availability and complete your appointment booking through the official visa scheduling service.
