Pereira will become an Inter player after completing a medical.
"Inter is a dream: you just cannot imagine how much this club is loved and supported abroad," he said.
"Inter is every player's dream and even more so in South America. I'm happy. The thought of playing for Inter is simply amazing. I can't wait to get the medical over so I can join the squad.
"Let's hope we can win a lot of trophies so we can make the Inter fans happy.
"I'll team up with Walter Gargano and Fredy Guarin, fortunately I have these friends here who will help me settle in with the rest of the squad quickly. Where do I prefer to play? What's important now is being at Inter and meeting my team-mates. What have Guarin and Gargano told me? That Inter is a fantastic club."
