Countries with retrogressive visa policies should not be allowed to host global tournaments.
The Somali referee Omar Abdulkadir Artan was reportedly denied entry into the US despite having a valid visa, meaning he will miss his World Cup debut as the first Somali official at the tournament. That alone tells you how broken this hosting model is.
You cannot invite the world to your country, collect tournament glory, collect tourism money, collect broadcast attention, then humiliate qualified officials and participants at the border.
Even the extortionist visa system at the US Embassy in Nairobi should be condemned. Kenyans pay money, fill forms, queue, wait for months, then someone rejects them in two minutes and keeps the money.
If your visa policy treats Africans like suspects and ATMs, you have no business hosting the world.
