Talking to reporters at the Attari border, Special Public Prosecutor A Choudary said they have come to India to collect evidence.
The judicial commission was earlier scheduled to come to India on September 11 but the visit was postponed due to the 10-day Ganesh Chaturthi festival in Mumbai.
The witnesses, whom the team intends to cross examine, include the magistrate who had recorded the confessional statement of Kasab, the chief investigating officer and two doctors who conducted autopsy on the bodies of other terrorists involved in the 2008 terror attack.
India had agreed to allow the panel to cross examine the witnesses to speed up the much-delayed trial in the case in Pakistan.
