The Home Ministry had said that the India will be ready with its team within a day or two.
Meanwhile, media reports said that the US Department of Justice has asked India to be prepared to sent over its intelligence team to question Headley.
Headley, who pleaded guilty to all the 12 counts of terror charges, including the Mumbai terror attacks, had struck an plea agreement with the US government under which he cannot be extradited to India, Pakistan and Denmark. The plea bargain also rules out death penalty against him.
