The World Motorsport Council confirmed the list today, with Korea also taking a provisional spot in next year's calendar.
New Jersey has been slotted in the middle of the Monaco Grand Prix and the race in Montreal, which some reports have claimed could cause controversy for the teams that deem the schedule impractical.
