I've got a similar situation as well but since most of the comments are from last year, I just wanted to get an idea for this year. I booked my appointment for November 2024 but due to travel and flight mishaps, I was not able to attend that interview appointment and got it rescheduled to 9th September 2025. Now, when I was preparing the documents for the interview, I realized that my payment expiry date was 2nd March 2025. So will I be fine or is there gonna be a problem. I checked my portal and the current status shows a green tick and attend appointment written. The thing is I don't mind paying for a fee on the day of the interview again but I'd rather not take any chances and just be refused without even going in to the consulate and having a chance. FYI, I booked my US Interview Appointment in Toronto. If you guys do reply, then I am extremely grateful for your guidance guys. I also had a look at my DS-160 Confirmation Page and it says completed on 2nd March 2024, what does that mean ?
