To the National Football Federations of the World,
Here is a template you can use to send to FIFA:
Unfortunately we have to decline your invite to the Qatar World Cup in 2022. It has unfortunately conflicted with our domestic season, and we will not be able to attend.
We have been in contact with several other nations, and we are hoping to work together to arrange an alternative in the summer of 2022. The location is yet to be determined, but the health and safety of the athletes, spectators, and those working to prepare the venues will be of paramount importance.
We would also like to advise you that we will be resigning our membership to FIFA with immediate effect. We do not feel confident that the organisation is being run with integrity or honesty, as the numerous investigations seem to indicate, and believe this is a good time for a change of direction.
