Pakistan spinner Abdur Rehman is set to make his long-awaited debut for Somerset on Wednesday.
Rehman, 32, agreed to join the Taunton club as their overseas player on 1 July but issues with visa clearance have delayed his arrival.
But he has now been given the go-ahead to face Nottinghamshire in their County Championship clash.
"I expect him to get runs as well as wickets," director of cricket Brian Rose told the club website.
"The great thing about having someone like Rehman is that world-class spinners can take wickets on any surface, especially when it comes to bowling out the tail.
"But he is a very useful lower-order batsman and it will be good to have a left-hander going in around number eight."
It will be Rehman's first foray in English county cricket and he brings with him a wealth of international experience, having played 17 Tests, 23 one-day games and seven T20 matches for his country.
