As all FIFA fans know that Offside is one of the laws of association football, but the offside offence is neither a foul nor a misconduct, players are never booked or sent off for offside. However, any play (such as the scoring of a goal) that occurs after the Offside has taken place but before the referee is able to stop the play is nullified. Players that continue such play may be booked based on the referee's assessment of how significant or intentional the play was.
mmogah as a professional fifa

What is the Offside rule?
means that players in an offside position, any of their body parts with
which they can touch the ball during the play; Players are in the opponents'
half of the pitch and closer to the opponents' goal
line than both the ball and the second to last opponent (usually, but not
necessarily always, the last defensive player in front of the goalkeeper).
in an offside position is not an offence in itself, only when the ball touches,
or is played by one of his teammate, the referee thinks that the player must
also be "actively involved in the play". When the offside
offence occurs, the referee stops you playing and awards an indirect
free kick to the defending team from the offending player’s position.
