Difficulty Booking U.S. Visa Appointment

Hi there,
I am trying to get a U.S. visa, but I have been struggling to book an interview slot. This is my third visa attempt, and I can not find an available appointment. The system always shows that no slots are open.

- I am checking the portal many times a day, but I can’t find any open slots.
- I have contacted the U.S. Visa helpdesk, but I haven’t received any helpful solution.

I am planning to attend California State University, Northridge where I have been accepted for a program starting in 13th of January 2025. I need to secure my visa soon to complete my registration before the university deadlines.

If anyone has been through the same situation or knows any ways to find open slots, I would really appreciate your advice. Any tips on the best times to check the portal or how to get an earlier slot would be great.

Thank you for your help!
