What is the correct entity to contact for an association wishing to apply for FIFA membership?

The correct entity to contact for an association wishing to apply for FIFA membership is the FIFA General Secretariat. This body is responsible for the day-to-day operations of FIFA, including handling membership applications and overseeing the administrative functions that support member associations. The General Secretariat provides the necessary guidance and resources for new associations seeking membership, facilitating the application process in accordance with FIFA's statutes and regulations.

While other options might seem relevant, they do not have the primary role in managing membership applications. The FIFA Congress is the legislative body of FIFA and is primarily focused on decision-making and governance rather than processing individual membership requests. The FIFA President oversees the organization but typically does not handle membership inquiries directly. The OFC (Oceania Football Confederation) is a regional governing body and does not manage FIFA-wide membership applications. Therefore, reaching out to the FIFA General Secretariat is the appropriate and effective course of action for associations seeking to apply for FIFA membership.
