We just received an email saying that our interview date is December 8th at 9.30. They gave us these instructions: "Prior to your interview, you must register in our service provider’s online system, select a DHL location for document delivery, and pay the $265 fiancé visa fee. You can find our service provider’s website here: https://ais.usvisa-info.com/en-rs/iv.
I did all this, but when it says we need to pay the fee, it doesn't take us anywhere where we can pay online. Below, it just says:
There are no available appointments at this time. Please check back in a few days as the Consular Section will open more appointments.
Now what? Should we email the embassy and ask for help? Has anyone encountered this problem before?
