Puerto Rico is a commonwealth associated with the United States.
''We are excited to welcome Puerto Rico to the USL family,'' said USL CEO Dave Askinas. ''The Islanders presented us with a unique opportunity to continue to expand our horizons internationally and enhances our link to the Caribbean beyond the handful of players who play in the U.S. and Canada with our other franchises.
''We feel that USL has played a critical role in developing the game in both the US and Canada and that through the Islanders, the Puerto Rican soccer federation and the city of Bayamon, we will be able to do the same in Puerto Rico and the greater Caribbean area.''
