Anonymous participant A year course is a plus.. So show you can support yourself for 1- 2 years . Ask Discover Nature if the embassy you will use has approved DTVs for them.
I know someone similar in Taipei approved via a substantial self managed portfolio, no registration of business but able to prove it is legit. Also in London, investors approved without business registration.
Which embassy are you applying from? Highlight you plan to stay much longer than 6mths seems like they are willing to give you a METV instead of the DTV. The course is hit n miss with embassies.
