I'm wondering about some certain details about WCG qualifiers.

For time needed each day for the people on a team to play is it just (assuming it's single elimination) 1 pre-game bans/picks organizing it and then the game itself or is more time required for something else?

It says you need to be a US citizen but I remember CLG had Canadians playing for their team last time (according to the stream from last years CLG). So is this the first year requiring this or do they have US citizenship too?
