the transatlantic and emea regions were geographically identical. leagues from the transatlantic region generally consisted of children and other dependents of american expatriates, typically armed forces personnel, international organization members, and oil company workers (such as the team representing the saudi aramco residential camp in dhahran, which advanced to the world series 19 times through 2007, including all the tournaments from 2001 through 2007). the leagues within the "emea" region consisted of players native to the league's own country. representative teams for the trans-atlantic region had to have at least 51% nationals of canada, the u.s. or japan, while teams for the emea region could have no more than three players from those three countries.
