The scheme is not being delayed by any policy issue, Indian High Commissioner T C A Raghavan told a group of reporters here.
"We have given the list of tour operators from our side. We await the response of the government of Pakistan. Once they give a list of tour operators from their side, the agreement can be implemented immediately," he said.
Raghavan, on an official visit to Karachi, said: "There is no policy issue holding up group tourism. I think your government has to decide who should be the tour operators who can use that facility."
Visas will be offered for 30 days to groups of 10 to 50 tourists organised by approved operators or travel agents.
The group tourist visas were to be launched from March 15 but the scheme could not start as Pakistan failed to send its list of authorised tour operators. The scheme also ran into rough weather after bilateral tensions escalated following clashes along the Line of Control.
