We constantly check for new interview slots at enrollment centers. Our special servers scan every second, giving SMS users an advantage by revealing new slots before anyone else. When an appointment opens, you'll get a text alert instantly. No need to keep refreshing the appointment page. Just check your phone to see if the time works for you.

By default, you'll be alerted for every new appointment at your chosen enrollment center. However, you can fine-tune this by opting for specific days of the week or selecting a cut-off date. Adjusting these settings allows you to receive alerts that precisely match your preferred days.
