This would give some tense moments to both the Indian diplomat and also New Delhi, sources said.
The State Department had received the necessary paper work for the UN transfer of Khobragade on December 20.
More than a fortnight after that the State Department continues to review the paper work and is taking an unusually long time.
The final option is to refuse to accept Khobragade's UN transfer due to pending criminal charges, the sources said.
Though the least preferred option, it is said to be advocated by those in the administration who want to “teach a lesson” to India for taking up retaliatory measures against the only super power of the world by removal of security barriers outside its Embassy in New Delhi and withdrawing privileges of its diplomats.
