New Jersey and Mexico were included on a 22-race Formula One world championship calendar for 2014 on Friday but will need to be confirmed.
The sport's governing body, the FIA, agreed the extended schedule at a World Council meeting in Dubrovnik.
But the street race in New Jersey, the return of F1 to Mexico as well as the South Korean Grand Prix are listed as provisional pending agreements with promoters.
The event in New Jersey, with the New York skyline providing a spectacular backdrop, will be a completely new event as will the Russian Grand Prix which will run around the site of the 2014 Winter Olympics in Sochi.
Next year’s calendar was announced by the FIA at a World Council meeting on Friday:
