It's happening this September and it will be the first time since the mid-80s that an event will be held at the old train station.
Homecoming Detroit is a special experience where successful people from all industries, with a Detroit connection, come back home and find a way to give back to the community.
Mary Kramer, who's the director of Detroit Homecoming, says it's a magical time.
"We invite them back for 2 1/2 days with the intention to re-engage," she says.
This year, 200 expats are expected to be here from September 13th to September 15th.
Matthew Moroun says, "We are anxious to see the reaction from the expats and dignitaries when they walk into Michigan Central Station on September 13th. The new windows on the 13th floor offer spectacular views of the city."
It's an invite-only event, but it will be streamed on WXYZ.com.
Cass Tech HS grad and comedienne Lily Tomlin will accept the Detroit Homecoming award and a key to the city. Speakers will include philanthropist Stephen Ross and Golden State Warrior Draymond Green.
