Matias Pellegrini and Julian Carranza have each received their green cards, opening up two international slots with Inter Miami.
The two 19-year-olds were Miami's first signings.
“We liked that Pellegrini can play inside and out wide, has very good aerobic capacity and can cover a lot of ground, while Julián is a very grounded player with an impressive work rate. He’s the player that strives to score goals and is very good in the box," Miami general manager Paul McDonough.
Miami currently has 24 players on their roster.
