Just FYI, appointments for registration of Visa are opened once, at the end of the previous month, for the whole of next month. Eg...For the whole of December 2023, they just opened it.
Why am I telling you this? If you have your travel dates, better book these dates early. For the last 2 weeks, I didn't know about this and there was no availability for my city. I arrived Saturday and since I couldn't find availability for "register visa," I chose one for PPT duplication just so as to get an appointment. I went there and had it not been for my persistence for 45 min, I would have gone back home empty. I stayed there and disturbed the lady 4 times until the supervisor allowed me to enter. Once in, they were just chilling. So, though I understand I chose the wrong category because for the one I wanted wasn't available, it doesn't make sense for them to just be chilling in the offices and sending people back home.
I looked right now and see they've opened availability for the whole of December 2023. So, better grab your appointment earlier.
