There is no requirement that time be added for a substitution. If the substitution takes longer than the referee thinks it should, he will add that extra time on to the end of the half. Typically, no more than 15 to 30 seconds will be added for a substitution, unless a player is cautioned for delaying the start or restart of play.
At youth levels of soccer, players generally line up at the midfield line and yell "sub ref" when they want to enter the field of play. At higher levels of soccer. A fourth official will communicate between the player and referee crew regarding a substitution. The assistant referees will signal with their flags above their head and the referee will give permission for the substitution to take place.
