DeAndre Yedlin will join Tottenham Hotspur in January after being granted a UK work permit.
Spurs agreed struck a deal with MLS side Seattle Sounders following Yedlin's impressive performances in the World Cup for United States but initially planned to allow the 21-year-old to remain stateside until the summer of 2015.
A string of injury problems at right-back, however, urged Tottenham to look into the possibility of bringing the defender to the club ahead of schedule.
Yedlin applied for a Latvian passport to speed up the process but MLSsoccer.com have confirmed his work permit has been approved in time to join the club in January.
Yedlin made his last appearances for the Sounders in their MLS Cup play-off defeat to LA Galaxy on 1 December. Following his MLS swansong, he also left with the award that gives him the title of the best young American in the game, after being named US Soccer Young Male Athlete of the Year by the United States Soccer Federation.
Yedlin revealed in October he had applied for a Latvian passport in order to boost his chances of gaining a work permit needed to complete his move to English football.
Not long after that, Tottenham boss Mauricio Pochettino confirmed the club were looking into the possibility of bringing the United States international to White Hart Lane ahead of a schedule having been beset by problems at right back all season.
First-choice-option Kyle Walker missed the first four months of the campaign after suffering a series of abdominal problems that required surgery in September. The England international has started three games since returning to training this month but Spurs have struggled in his absence.
Kyle Naughton, Eric Dier and Vlad Chiriches have all been deployed on the right-hand side of defence in Walker's absence but to little success.
