Scott was born in England, but has United States and Ireland passports. He has played for all three countries' national teams, first with England's U-16 team, then Ireland's U-17's, before joining up with the U.S. He played with the Americans at the U-18 level and, most recently, with the U-20's at the Stevan Vilotic Tournament in September. He is still eligible to play for any of the three countries and does not have to file any one-time switches because none of the competitions he has played in were official tournaments.
Chelsea are very excited about Scott's future and have pushed him through their academy quickly since signing him in 2014. Last year he played for the Blues' U-19 and U-21 teams, making over 20 appearances between the two and playing a prominent role for both. The midfielder has been praised for his passing ability and will certainly be featured for the U.S. youth teams as often as he wants to play for them and Chelsea are willing to let him go.
