The move was announced by the 2019/20 P2 champion team in the wake of confirmation on Friday that there will be no P2 class in the world championship next season.
United, which is co-owned by McLaren Racing boss Zak Brown, will make its first full-season IMSA assault with a pair of ORECA-Gibson 07s while continuing to compete in both the European and Asian Le Mans Series next year.
Team boss Richard Dean explained that the “redirection of our entire WEC team” to IMSA was for the “foreseeable future”.
He revealed that competing in IMSA full-time was a long-held ambition for United after taking in a total of eight races in the North American series since 2018.
“It’s easy for us to say that we have always wanted to do a full season in IMSA right now, but it’s true,” he told Autosport.
“This has given us the necessary kick up the backside to go and do it.”
