New York City FC head coach Patrick Vieira believes that the addition of Ebenezer will help to raise the level of every player at the club.
The former France captain played a key role in securing the loan deal for the Ghana international from German Bundesliga outfit Stuttgart.
Viera believes Ofori's influence-particularly in the middle third-will be crucial for his side this season which starts next month.
He said: "I'm really excited to bring in Ebenezer - he's a young player who is looking to improve, he is really dynamic and can cover ground. He's really aggressive but he's good with the ball too. I'm really pleased that we managed to bring him to the football club.
"He's a competitor, he's a guy who likes to win, he's a strong character. He's coming to this club to compete with the midfielders we have and, like I always say, that will bring the best out of all of the players we have at this football club."
Sporting Director Claudio Reyna feels that Ofori's competitive spirit and quality will add plenty to a strong NYCFC midfield.
"Ebenezer plays as a holding midfielder that can help dictate the tempo of the game with his quality passing ability. He has good technique combined with a very good game understanding that will provide another element to our team.
"We are very happy to add him to our strong midfield unit and look forward to seeing him grow as a player at NYCFC."
