Quite unfair, isn't it?

Anyway, it is what it is because America's closest allied countries are really granted with an almost easy access since then. That said, they will have the most advantage in this event because they will not be having any troubles in entering towards US soil compared to other people especially if they came from a 3rd world country, but there should be no problems at all to watch this event as long as they have the correct requirements and completed every check that they placed before you will be granted an access.
That is probably the only major problem people will face during the next world cup, the US is very strict with its policies and getting a visa will probably get harder as they will probably receive millions of applications to watch the games live, I suppose that for soccer fans one of the basic requirements to get a visa to watch the games will be to have bought a ticket already and have a place to stay, still it would not surprise me if under those conditions many people were still denied entry and they will fail to make it to the world cup.
wait, so the next world cup will take place in the US?
crazy stuff didn't expect it
don't you think they'd be at least a bit more open on the visa thing for people going to the event?
