Spinner Saeed Ajmal is confident he will be "as effective as before" with his remodelled bowling action.
Ajmal, who played for Worcestershire in 2011 and 2014, is being sent to the National Cricket Performance Centre at Loughborough University on Monday by the Pakistan Cricket Board for an informal test on his new action.
He was suspended from international cricket in September by the International Cricket Council after his action was reported during the Sri Lanka-Pakistan series in August and then failed a bio-mechanic test at the ICC centre in Brisbane.
Ajmal, who helped Worcestershire gain promotion to Division One of the LV County Championship with 63 wickets in nine games last season, is hoping to be cleared to play in the World Cup in February.
The 37-year-old told reporters in Lahore: "I am scheduled to be sent next week by the Pakistan Cricket Board for a private test and have already applied for the visa.
"I have worked hard on correcting the flaws in my action and have made some minor changes to it.
"But I am confident that even after the changes, I will remain as effective as a bowler as I was before being suspended.
"I am confident of a strong comeback to competitive cricket before the World Cup."
Ajmal has been working on remodelling his action in Lahore at the National Cricket Academy (NCA) with former Pakistan spinner Saqlain Mushtaq.
He said: "I have been constantly tested with the cameras installed at the NCA and I am hopeful I will also clear the informal test in Cardiff.
"I am comfortable bowling with the new redesigned action so I am confident and I remain effective as before."
