Representatives for the White House and 10 Downing Street said Trump would visit the United Kingdom on July 13 and hold bilateral talks with May but gave no other details.
It was also not immediately clear how long Trump would stay on his visit, which would come more than a year after taking office.
The delay has raised questions about the U.S.-UK relationship, and the working visit signals a more low-key affair than an official state visit.
Trump had planned a trip to London to open a new U.S. embassy there but canceled in January.
Many Britons have vowed to stage protests if Trump visits.
