Leffen (The best SSBM fox player in the world) got deported back to Sweden and banned from the US.
Only LOL and Dota players can get P1 Visas (Allows professional athletes to live in other countries to compete) and Leffen was denied a P1 so he got a vacation Visa.
He was deported for not paying taxes to the US government.
Although Leffen should have got at least a work permit and paid taxes.
