Correct as far as I understand. Technically, Hombu is supposed to wait for a practitioner to have his/her federal grade before awarding Aikikai grades. In France it is illegal to use the word Dan if it was not given by a state-recognized commission.
So what happens if I received my Dan grade from Japan or some other country where the state is not involved and move to France.
In Germany it is illegal for a scientist to call himself Dr. unless that Ph.D. was from a German university or an exception applied for and granted. I just can't fathom the thinking behind this - who comes up with these laws and why.
