The International Rugby Board has released a document detailing the necessary requirements for players to switch nationalities.

Players looking to represent another country will have to play in a minimum of four Sevens World Series legs for their conversion to be approved, along with adhering to other terms.

All players who apply this way will also have to take part in the Olympic Games in Rio in 2016.

The document also states that players will not be able to revert to their former union should their application to play for a second Union fall through.

Fiji is amongst nations, who players who have played for other nations want to switch back to their home nation.
