Hello,
I can't help you with a particular instruction, but I will give you some food for thought as a decision support:
Every year, thousands of Namibian students with their bachelor or even master in Tourism are flooding the job market looking for employment. When it comes to employing someone, Namibians will always have preference before foreigners. For Namibia, it won't make any difference where you studied - you will not get any job as long as there are Namibians with the same skills and training.
Foreigners are expected to invest, and to create job opportunities rather than "taking them away" from Namibians, so the most promising way of immigrating into Namibia is to invest into an already existing Namibian business, or to set up a company yourself and employ a number of Namibians.
As far as I have learned, in Tourism it's not an advantage to speak some of the Namibian languages (Namibians will always beat you there), but to be fluent in English (the official language of Namibia) and other European languages (it's mostly Europeans and Americans who support Namibian tourism, not Namibians), and maybe additionally Russian and Mandarin.
I don't say your dream is impossible to come true, but it's a long and rocky road and you might find out eventually that you have bitten off more than you can chew. I won't recommend it as I also want Namibians earning a living to be able to sustain themselves. There are many jobless people here.
Yes, I am all "Namibians first" when it comes to jobs they are qualified for, or able to fulfill. Which is also the official position of the Government.
good luck anyways
