Shouldn't a work permit be involved

I have had one PM to this subject which I have tried to respond to but failed. However thank you for the PM, very helpful

Thanks tigertiger but finances don't come into it, it's purely his wish to enter into technical courses in Germany, which I would imagine that the German language would be used.
All Google checks show this.

My wife's nephew is hell bent on studying in Germany.
Of course a rudimentary knowledge of the German language would be required.
Are there any German language lessons available in KM or is there a German speaker who would be interested ?

Now here is more confusion.
I was told when I passed my test in KM at the age of 61, that my licence could not be renewed after I reached the age of 70.
Then during my efforts to renew my present licence, I was informed as it was no longer valid, I could sit another test and if I again passed, then my new licence would be valid until I reached the age of 70, and could be renewed after that by taking an annual medical.
Confusion abounds .
