Beginning on April 15, 2025, visa applicants will be required to present a DS-160 visa application form with a confirmation or barcode number that matches the one used for scheduling their appointment online. This number typically begins with "AA."
Applicants whose confirmation numbers do not align will be ineligible for the interview and instructed to book a new appointment. Appointments can be scheduled through the provided online platform: https://ais.usvisa-info.com/en-pt/niv.
To ensure a smooth interview process, applicants are advised to confirm the matching of barcode numbers before their scheduled interviews.
