How does a country's football team enter the World Cup?

The World Cup qualifiers are divided into six divisions, namely Europe, South America, Asia, Africa, North America and Oceania. Each division needs to formulate the rules of the qualifiers according to the actual situation of its own division, while teams from FIFA member countries (regions) who sign up for the World Cup need to conduct qualifiers in their respective divisions to compete for the places in the World Cup finals. At present, there are 32 places in the final stage of the World Cup, and the host country can directly obtain the places in the final stage. Except for the host country, other places are allocated by FIFA according to the football level of each qualifying area, and different qualifying areas will have different places in the final stage. Note: FIFA stipulates that from the 2006 World Cup qualifiers, defending champions need to participate in the World Cup qualifiers in their respective regions, so that only the host country can enter the top 32 finals.

The host country of the final stage of the World Cup must be a FIFA member country (region). Member countries (regions) need to apply to FIFA (two member countries can jointly apply for hosting), and then all FIFA member countries (regions) will vote to decide. A total of 32 teams will go to the host country to compete for the championship in the final stage, including the national team and the host country team that won the finals through the World Cup qualifiers. In the final stage, 32 teams will be divided into 8 groups by lottery, with 4 teams in each group and the top two teams in each group, with a total of 16 teams, which will qualify for the semi-finals; After entering the semi-finals, 16 teams decided the schedule according to the established rules, no more lottery, and then single elimination matches were held until the champion was decided.
