Compared to many other countries, I know visiting the USA is harder for some people because they have more special rules for the people who come to visit this country but I think during the 2026 world cup they have to change some rules and make some new rules for the people who come to this country to watch the world cup games otherwise we will see even worst world cup than what we saw in Qatar.
The situation in United States is very different compared to other countries. In the US, it is very easy to enter that country as an illegal immigrant. But if you follow the rules and try to get a legal visa, then you may wait for many years (and even then your visa may get rejected). More than 6 million illegal immigrants have entered the US in the last 3 years, which amount for 2 million per year. But with each passing year, it gets more and more difficult to migrate to the US through legal means.
The American reasoning is that they don't need skilled and educated migrants, but illiterate ones are welcome since there is a shortage of manpower for blue collar jobs. That is strange, because I thought that US welcomes everyone who wants to work, get paid and pay taxes. It does not matter if you are skilled or not, educated or not - if you want to work and be useful, you are welcomed. Take New York for example. A cocktail of multi national people, crazy, talented and smart. Btw their MetLife Stadium will held World Cup matches

This stadium has biggest capacity among US stadiums that gonna be used during cup.
I think we are slowly going to off-topic abyss. One of the things I like about this World Cup, is that is going to be super safe for tourists.
