This year's Miami world cup was not a country qualifier. Next opportunity will be the 2015 Worlds where 3 country places will be up for grabs. If a spot isn't secured there, 1 spot will be available at a Continental qualifier (likely 2016 Miami).

Countries that have qualified: FRA, ARG, AUS, ITA, NZL, SUI, GBR, DEN, AUT, NED
