Pakistan has a system of giving visas to Indian journalists for a few months at a time and they are then required to repeatedly seek extensions.
India and Pakistan had reached an understanding in late 1970s for posting of two mediapersons from each country.
PTI has regularly posted correspondents in Pakistan since then and some Pakistani journalists were stationed in India from time to time, although currently there are none from Pakistan.
Pakistan had also expelled New York Times correspondent Declan Walsh last year at a short notice without any explanation.
