US visa appointment system in Brazil limits rescheduling

The official United States visa appointment system in Brazil has implemented a new restriction allowing a maximum of three cancellations or rescheduling attempts. According to reports from visa advisory services, once this limit is reached, the appointment is blocked. Neither the applicant nor the system support staff will be able to reschedule the appointment for a new date or time.

The warning appears in the system before a new date is confirmed, informing the user of their remaining attempts. The rule also applies to individuals attempting to move their appointments to an earlier date. The system does not currently specify when this rule took effect, how it affects consular fees for those blocked, or whether missing a scheduled interview counts as a rescheduling attempt.
