"I'm going to Arizona State on October 19th when they play Washington," said Calhoun.
Calhoun, who's graduating in December with plans to enroll in January, said he may visit USC the next month or even before the Arizona State trip.
"It might be on November 16th (when USC hosts Stanford), or I might take one during the week before Arizona State," said Calhoun. "I'm not sure. I'm not wanting to wait too much because I'm graduating in December."
Calhoun said that California could also get an official visit out of him.
"I might take one to Cal, that's probably the only other one in mind," said Calhoun. "I went to the Northwestern game and it was a good experience. I like Cal, it's in my backyard and I like their defensive coaches."
Calhoun said UCLA, who was his finalist with USC when he picked the Trojans, may not be an option.
"Adarius is working on me and on them, but I talked to them and it doesn't sound like they have any spots for linebackers," said Calhoun.
Oklahoma has also been showing renewed interest in Calhoun, and he's open to the Sooners, though for now, he's focused primarily on playing in the Pac-12.
And as far as Calhoun is concerned, that will be at USC.
"I still consider myself a USC commit," said Calhoun. "I talk to Coach (Clay) Helton and Coach (Clancy) Pendergast and they still want me there."
Arizona State coaches were at his school this past weekend when they were in town to play Stanford.
"Coach (Chris) Ball and Coach (Paul) Randolph, I love those guys," said Calhoun. "They're recruiting me hard. They were juiced when I said I wanted to visit and they are trying to get me back and said they would try to get me with Arizona State. I never really gave them a chance so that's why I want to take a visit."
Calhoun said that Sun Devils quarterback commit Manny Wilkins, a Bay Area native, is also working on him consistently.
"Manny has been a big help, now I consider him as family," said Calhoun. "I wouldn't mind being on the team with him. He's a leader and I saw him leading all the time at The Opening."
And Calhoun's close friend, Michael Lazarus, is also favoring the Sun Devils heavily.
"Mike and I have wanted to play together so there is still the chance that could happen," said Calhoun.
Calhoun said that it's looking likely he stays at linebacker, though some schools early on talked about safety.
"Coaches know I'll book up and they like my linebacker instincts," said Calhoun.
Calhoun was recently invited to the U.S. Army All-American Bowl, a dream come true for him.
"I'm really excited about that," said Calhoun. "Not too many people get to do that so I'm blessed."
