Getting a hotel room in Qatar during the 2022 World Cup was insanely expensive, according to reports from many of the fans. On the plus side, getting a Qatari visa is relatively easy. But then, there are additional restrictions such as complete ban on unmarried and LGBT couples. Such couples are not allowed to stay together and need to book separate rooms. In the United States and the other two countries, there are no such restrictions. But getting a US visa is going to be hard, especially if you are from one of the third world nations. Mexico and Canada doesn't have too many restrictions on the visa, but these two countries are not going to host a lot many matches.
Unfortunately, it will be increasingly difficult for ordinary fans to personally participate in world cups and cheer on their national teams in the future, the financial costs will be astronomical for ordinary people.
Obviously, only rich fans, who have enough money and free time, and can easily get a visa, will be able to participate in world cups in the future.
In this way, FIFA will probably get rid of problematic fans who cause problems and do not spend much, and will get rich fans who spend a lot and do not cause problems at matches. Is this actually FIFA's long-term goal?
