hey there rosalea,
I wish I had an answer fo you, but I personally don't.
I started searching online for people's experience. We too are at the same step in the process, and of course, find it ridiculous that this step is just yet another limbo- lucky win of the draw type thing. We're checking the website morning and night and hoping to see something pop up and im just hoping we don't have to do this, like you said, for months to come!
And when an appt will become available, will it typically be months out from the day it appears on the website?
Hopefully someone comes along that recently got an appointment and can shed some helpful info.
Until then, at least its good to empathise with someone else going through the visa ringer!
