The former diplomat told a media conference in Lahore that he plans to meet with the BCCI hierarchy and other government officials to discuss the scheduled series.
"There is a real danger at this time to the series. But I plan to go to India to get a clear answer on the prospects of the matches being held in December," Khan said.
"I want to have frank discussions with the relevant officials in India because we can't delay preparations for too long and we need to know where we stand," he said.
Khan said the positive aspect of the whole episode was that so far the Board of Control for Cricket in India (BCCI) was also ready to play the series but were waiting for a confirmation from their government.

Khan, who has remained a high commissioner in New Delhi and also foreign secretary also admitted that the present political relations between the two countries could have a bearing on the series.
"I am doing everything to convince the governments to allow this series but the present political relations will have an influence and we don't know what the situation will be in the next six months," he said.
Khan pointed out that many former greats, the PCB and even the international cricket community were off the opinion that Pakistan and India should play regular bilateral cricket.
Khan said the PCB hoped that the BCCI will honour the MoU and there would be a green light from the Indian government soon for the series in December. "If this does not happen it is not good for cricket overall.
