The United States Olympic Committee has chosen four cities as finalists for a possible United States 2024 Olympic bid.

Los Angeles, Boston, San Francisco, and Washington D.C are in the running to host the Summer Olympics. Los Angeles has hosted the 1932 and 1984 Olympics. The other three cities have never held the Olympics.

The USOC will decide whether it wants to try to host the Olympics. The last two US cities finished in fourth-place, New York for the 2012 Olympics and Chicago for the 2016 Olympics, during voting.

Paris, Rome, Doha and Istanbul are among the possible cities that could enter the race. The International Olympic Committee has also long state a desire to bring the Olympics to Africa for the first time, as the AP reports.

The USOC is waiting to see what changes the IOC might make in the bidding process later this year.

“We clearly want to see the output from that working group and what changes are adopted before we push the ‘go’ button on 2024,” USOC chairman Larry Probst told the AP earlier this week.

The USOC will visit each city over the next couple of months to review plans and build relationship, the Boston Globe reports.

“[The committee] is going to be making sure that the cities have the land and the buildings and the wherewithal and the consensus to do what they said they can do,” Scott Blackmun, USOC chief executive, told reports on Tuesday. “It’s a lot of land planning, it’s a lot of discussion around the host city contract, around the terms of our joint venture with each city.”

The IOC will choose the host of the 2024 games in 2017.
