Development
On January 12, 2020, it was reported that Dick Wolf was having conversations with CBS Entertainment President Kelly Kahl about launching a second FBI spinoff, following the success of the first spinoff, FBI: Most Wanted. Wolf claimed he always envisioned FBI as a franchise, as it offers an "endless trove of stories", while Kahl states "We are always talking to Dick [Wolf] and Dick is always bouncing ideas off of us and I can't rule anything out." It was also reported that development of the proposed spinoff would begin during the 2020–21 television season.

On February 18, 2021, it was announced that a second FBI spinoff titled FBI: International was being developed for the 2021–22 television season. Derek Haas was announced as the series showrunner and one of its executive producers, alongside Wolf, Peter Jankowski, and Arthur Forney. The new series is also likely, to begin with, a backdoor pilot. On March 24, 2021, CBS officially ordered the series, announcing it would debut in a crossover episode of FBI and FBI: Most Wanted, with Rick Eid also being added as an executive producer.
