The competition organization can decide whether foreign athletes are allowed to participate. They can set this up as follows: Via the drop-down menu on the right --> "Clubs" --> "Allowed clubs" --> Select the countries that you also allow at your competition.
If you are a registrant and see that the organization does not (yet) allow foreign athletes, you can contact the competition organization. They can help you with this. You can find the contact details of the competition organization here:
