The F1 calendar for the 2014 season features 22-races however three venues remain unconfirmed.
After the recently issued draft calendar the grand prix schedule was released by the World Motor Sport Council which now features the previously omitted New Jersey street race.
The Grand Prix of America at New Jersey on June 1, the Korean GP on April 27 and the Mexico City race on November 16 are all listed as provisional.
A definitive calendar is now not expected to be finalised before December.
However the Australian GP at Albert Park remains locked into its March 16 date and will, as has been tradition, kick off the championship.
There remains grave concerns that the New Jersey race overlooking the Manhattan skyline will not get off the ground.
As the provisional schedule came to light, the highly secretive Concorde Agreement has been approved by the FIA and Formula One Management but is now waiting on the signatures of the 11 teams to be fully ratified.
The agreement which made its entrance into the sport in 1981 is a commercial document which sees defines how F1 is run and how the revenue is distributed.
In other developments Pirelli is set to continue as the sole tyre supplier after a rocky period this year through a series of tyre failures.
