Here's a simple way of verifying whether a dojang is FIK sanctioned or not. Legit kumdo dojangs are either affiliated with AUSKF or the Korea Kumdo Association. (KKA is the only FIK sanctioned body in Korea.) Most KKA-affiliated dojangs with website usually display the KKA logo (which you can see at below websites). There are two KKA federations in the US:
KKAUSA (Western US)
KKA USEKF (Eastern US)
