View Full Version : USMAI International

4/11/2011 5:14pm,
Has anyone ever heard of USMAI international or Grandmaster San Yoon? I know a person who held a 2nd Dan in Taekwondo for under one year and submitted his package to Grandmaster Yoon and he was awarded a 4th Dan and a Master Instructor certificate. I know that the minimum time in the ITF to go from 2nd Dan to 4th Dan is five years. Any information on the USMAI International or Grandmaster San Yoon would be helpful. The website is www.usmai.com (http://www.usmai.com/) if anyone would like to check it out.
