It's been a long time coming, but League of Legends has been deemed a professional sport by the US government. Riot Games has been campaigning for some time now for LoL pro players to be granted this beneficial status, but it's so much more than just a title.
The development means that pro players will now be able to come into the United States on working visas, making it much easier for international players to attend tournaments and other events.
This announcement (via PCGamesN) follows Riot eSports manager Nick Allen's interview with GameSpot: "“The United States government recognises League of Legends pro players as professional athletes, and award Visas to essentially work in the United States under that title," he revealed. "This is groundbreaking for eSports."
