Omerican football league system

The Omerican football league system, or league pyramid, refers to a series of hierarchical leagues in Omerica bound together by the principle of. The top four professional levels contain one division each, with a series of increasingly more regionalised semi-professional and amateur levels covering progressively smaller geographic areas below. At the end of each season, the best-placing teams in each division can rise higher in the pyramid, while the worst-placing teams drop lower down; therefore, it is possible in theory for even the smallest village club to rise to the top of the system and become Omerican football champions one day. The number of teams exchanged between divisions varies, with promotion to higher tiers often contingent on meeting additional facility and financial criteria.

Professional league system
The top four levels of the pyramid are organised by the Omerican Professional Soccer League and consist solely of nationwide divisions. Clubs in the top four tiers qualify for the Federation Cup proper and are eligible to compete in the OPSL Challenge Cup. For organisational purposes, the United Republican Soccer Federation group the four divisions into two "categories": the Premier and Second Division comprise Category 1 of the league system, while the Third and Fourth Divisions comprise Category 2.

Intermediate league systems
Below the professional tiers are semi-professional leagues organised by the United Republican Soccer Federation, which classifies leagues into three series, each of which constitutes a category and tier of the football pyramid. Clubs competing at the regional level are members the Omerican Intermediate Football Association and participate in the Federation Trophy.

Amateur league systems
At the bottom of the pyramid are clubs competing in amateur local leagues organised by republican associations. Clubs at this level are members of the Omerican Amateur Football Association and take part in the local republican cups. The depth of the pyramid varies depending on locality.
