The left-armer will be available for six matches, starting with the fixture against Worcestershire at Cheltenham from Thursday, August 20, followed by two games in Bristol against Derbyshire and Middlesex, and away trips to Durham, Lancashire, and Kent.
Kishore has built a reputation as one of India’s top domestic red-ball bowlers, taking 223 wickets in 54 first-class matches for Tamil Nadu.
He previously played in the County Championship for Surrey in 2025, where he claimed his first five-wicket haul in the competition during a win at Durham.
Sai Kishore said: “I am deeply grateful to Jon and everyone at Gloucestershire for giving me this opportunity.
“Gloucestershire is a club with a rich history and a fantastic setup, and the chance to play my cricket here is incredibly exciting.
“I’ve always wanted to test my skills in English conditions, and after speaking with the management, I knew this was the right fit.
“I’m looking forward to wearing the jersey, meeting the fans at Bristol and Cheltenham, and doing my part.”
Jon Lewis said: “We’re really excited to bring Sai Kishore into the squad.
“He’s a proven, experienced cricketer who will add a huge amount to our group.
“The Club is fully committed to playing better cricket over the final six County Championship matches, and it’ll be really interesting to see the impact an overseas spinner can have at this stage of the season.
“The conditions at this time of year are often very conducive to spin bowling, so we’re hopeful Sai can make a significant contribution and have a really positive impact on the team.”
Outside of first-class cricket, Kishore has made 28 appearances in the Indian Premier League, taking 33 wickets at an average of 21.12.
He was also part of India’s gold medal-winning squad at the 2022 Asian Games, playing a key role in the semi-final with a three-wicket haul.
