there is no limit on the number of international slots on each club's roster. the remaining roster slots must belong to domestic players. for clubs based in canada, a domestic player is either a player with the legal right to work in canada (i.e., canadian citizen, permanent resident, part of a protected class) or a u.s. citizen, a permanent u.s. resident (green card holder) or the holder of other special u.s. status (e.g., refugee or asylum status).
