Here are my questions and they all relate to starting a WTF school here in the United States? 1. What Dan level do you have to be at to teach? 2. How do you go about promoting through Kukkiwon? 3. Can you promote to your Dan level or one step below? (ex. 1st Dan promoting someone to 1st Dan) ( or 2nd Dan Only being able to promote to 1st Dan) 4. If you have to be a certin Dan level (above 1st) can you have another master perform the promotion tests for your students?
