I'm pretty sure you apply at the same time. There's a course in CM with some cooking and more language. DM. I'm on DTV soft power to learn Muay Thai. Applied in Taiwan though.
I'm pretty sure all of Africa now applies through South Africa. I checked multiple countries in the EVisa system and they all said SA. Even ones that previously used Nigeria and Egypt.
Nice! Glad I got my licence renewed last month while I was on an education visa. Getting the DTV next month. Hopefully in 2030, they will accept the DTV as a longer term visa.
