Do you need a special permit to work in Africa?
Don't they have a type of VISA for that??
The company will arrange your work visa as appropriate.
Can you have a say in where you fly? ie. Botswana or Namibia. I'd be looking at going for a couple years and would be more than happy flying a 206 in Maun.
I don't work for them but, no people who do and therefore passed an opinion which is that they're a good operation. If you do a search for Maun you'll get a lot of information there. There are several companies in Maun, Namimbia, Zambia,Tanzania and Malawi to a much lesser extent. A couple of years is a good target for you and them so yeah, give Sefos a try.
