Which FIFA body decides on the admission, suspension, and expulsion of a member association?

The FIFA Congress is the primary decision-making body of FIFA that is responsible for significant matters regarding member associations, including their admission, suspension, and expulsion. The Congress is composed of representatives from each of FIFA's member associations and convenes regularly to discuss and decide on important issues affecting football globally, including governance, rules, and membership status.

This body has the authority to vote on the admission of new members and to make decisions regarding any member association that may face suspension or expulsion due to violations of FIFA regulations. The Congress represents the highest level of authority within FIFA for these matters, ensuring that all member associations are treated fairly and according to the established statutes.

In contrast, while the FIFA Council has some level of oversight regarding member associations, its primary functions do not include the direct admission or expulsion of members. The General Secretariat handles the day-to-day operations of FIFA but does not have the authority to decide on member status. The FIFA Disciplinary Committee deals with specific disciplinary issues and enforcement rather than the overall membership status of associations. Thus, the FIFA Congress is the correct answer as it embodies the democratic process through which FIFA governs its member associations.
