If you wanna see the "pro" status application for Hawaii go to :
hawaii.gov/dcca/pvl/programs/mma/applica...ion/mma-multiapp.pdf
and
hawaii.gov/dcca/pvl/programs/mma/mma.html/?searchterm=mma professional
If a fighter has paid their registration fees and submitted that application and holds professional licensing, then according to DCCA they are professional.
Read the same discussion a few months ago here on mmahawaii.
So, no professional registration and licensing = amateur. I know since one of my drivers is a licensed ref.
