Gio Reyna and Christian Pulisic were among 24 players named in the United States squad for a training camp in Orlando ahead of the CONCACAF Nations League final four, U.S. Soccer said on Wednesday.
The U.S. are bidding to retain the title and qualify for this year's Gold Cup.
It will be the full squad's first meet-up since last year's World Cup.
"We come out of the World Cup knowing we're capable of more, and we're excited to keep moving forward in this group," said interim manager Anthony Hudson, who replaced former coach Gregg Berhalter in January.
