Hello, I applied for a US visa using the Visa Waiver Program and submitted my documents on July 3rd or 4th. However, I didn't receive any updates or status changes until July 18th, when I saw that my application had been received. Two days later, I checked again and saw that my status had been updated to 'Approved'. Then, yesterday, it changed to 'Issued'. What does this mean? Is my visa complete and stamped without an interview, or do I still need to worry that I might be required to attend an interview before receiving my passport? The current status is 'Issued', and I've been told that my passport will be delivered within 10 days.
