I have Bulgarian citizenship and permanent residence address in Germany, and I will travel to Botswana for a 10 day trip (scientific conference). The site of our Ministry of External affairs states that I don't need a visa for Botswana.
However, I have to change planes at Windhoek International Airport. Our ministry's site states that I need a visa if I want to visit Namibia, but does not say anything about transit.
I tried to find out on https://skyteam.traveldoc.aero/, but did not find a way to input my correct flight details with the layover. So do I need a visa for my travel?
If I have to get the visa, do I get it from a consulate in Germany, or for the consulate accredited for Bulgarians (which is in Vienna)?
