Top officials of Pakistan Hockey Federation had recently announced separate schedules for hosting the bilateral series in June-July but a HI source said they were yet to approach the government for clearance.
The source said HI will seek clearance for the tour only after a new government is in place.
"We are committed to the tour but we haven't sought permission for it yet. There is no point in putting the request now as a new government will be in place soon," a top HI source told PTI.
Both the PHF and HI had earlier agreed to hold the series in March-April, but the event got postponed because of the delay in getting permission from the respective governments.

PHF president Akhtar Rasool and secretary Rana Mujahid had recently announced separate dates for the bilateral series.
While media reports quoted Rasool as saying that the Indian team would arrive in Lahore on June 19, just after the World Cup at The Hague, Netherlands for the three-match series, Mujahid said India would reach Karachi on June 30 with the matches scheduled for July.
The HI source, however, refused to confirm the dates.
"Nothing has been finalised as yet. So there is no question of announcing the dates," he said.
The traditional rivals last played a bilateral hockey series in 2006 -- three matches in each country. Pakistan won three and lost one while the remaining two were drawn.
A home-and-away series between the two countries was called off last year after the Indian government refused permission for the rubber on security grounds.
