Team SoloMid (TSM) is a professional eSports organization based in the United States. Founded in 2009 as the team of League of Legends community site SoloMid.net by brothers Andy Dinh (Reginald) and Dan Dinh, it became one of the most popular and successful League organizations before expanding into Hearthstone with some of the most popular players in that scene.
They entered Smash by signing the Melee player Leffen on March 10th, 2015. Later that year, ZeRo would also get sponsored, now expanding with in the Smash 4 scene. With those recruitments, TSM boasted two of the best and popular players in their respective game. Three years later, ZeRo left TSM after announcing his retirement from the Smash 4 scene. Now, with Super Smash Bros. Ultimate released, TSM expanded into the scene by sponsoring Tweek.
Leffen's work visa situation
Because Leffen is from Sweden and Team SoloMid is an American sponsor, the United States considers Leffen to be "working" in the country, which would require a worker's visa. However, as Leffen did not have one, he was denied entrance to the country in October 2015, causing him to miss out on The Big House 5 and four other American tournaments. Although Leffen was temporarily allowed into the country up until the end of July 2016, which allowed him to attend EVO 2016, because his visa was going through additional processing during that period of time, he was eventually deported from the country, causing him to miss the tournament. In addition, his work visa was denied, primarily for reasons that questioned Melee's legitimacy as a sport. The video showing the rejection letter started the #FreeLeffen movement in hopes of reversing the decision. Due to the movement, a petition was created on the White House petition site "We The People" in hopes of having the country recognize esports as a legitimate sport, however the White House declined to address the issue. On October 3rd, 2016, Leffen's US visa was fully processed and approved, allowing him to enter future tournaments such as EVO 2017.
