Visa Information: Effective immediately, the barcode number on your DS-160 form (the number starting with “AA”) must be the same as the one in your appointment profile. If the barcodes don’t match, you must edit your profile to input the correct barcode at least 2 business days before your appointment or it will be cancelled. Book your own appointment or ask a trusted family member or friend to help you. You do not need to pay for a third-party service.
