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.

The app's Alerts section shows your preferences, history, and rank. Enable notifications on your eligible device for mobile alerts.
