Thisislife, I'm sorry that you had such a terrible experience... It might have been incidental though, because my husband and I travelled to Namibia in November to investigate the possibilities of immigration. Honoustly, people couldn't have been more friendly and helpful. The regulation is strict, yes, exams for the assessment of previous education are though, but that's a good thing, because they care about their own population and don't want to let in, for instance, a medical doctor who can't validate his/her expertise. My impression was that the evaluations are fair.
The people we've met were not racist, on the contrary, our conclusion was that people from different backgrounds really cooperate well and are well-integrated.
So probably, like anywhere in the world, you have negative people, but we spoke to a huge number of people who were really positive and friendly, even exceptionally helpful.
