The 17-year-old is rated as one of their brightest prospects and he shone in the recent Milk Cup.
He caused a stir in Mexico when he opted to leave Chivas to play for USA's youth side.
Chivas youth policy means all their players must be eligible to play for Mexico - but Salgado opted for USA, meaning he left the club.
He is now tipped to one of the top picks in the forthcoming MLS draft, and has been training with Portland Timbers, but in the mean time he has now joined Everton for a training stint.
Everton have strong links with America forged in recent years, and in the last few weeks Salgado's US Under-20 team-mate, goalkeeper Zac Macmath, also spent time with the Toffees.
