Christian Pulisic, Weston McKennie and Folarin Balogun headline the 24-player roster that will prepare for the final four of the Concacaf Nations League.
The roster marks the first under interim manager B.J. Callaghan, who was appointed earlier this week after predecessor Anthony Hudson departed to take up a managerial post with an unidentified club in the Middle East.
Leeds United midfielder Tyler Adams is injured and did not make the squad. Adams was listed on the preliminary roster last month despite undergoing hamstring surgery in March, ruling him out for the rest of the Premier League season.
