"From 2012 till April 14, 2017, a total number of 298 Indian emigrants have been granted Pakistani citizenship," the Interior Ministry said in a statement on Saturday.
In 2012, 48 Indian emigrants were granted Pakistani nationality, which rose to 75 in 2013 and 76 in 2014.
Pakistan is believed to be a country where getting nationality has always been a difficult task, but innumerable illegal immigrants from many countries, especially India, Afghanistan, Bangladesh and Burma, are living in Islamabad, it added.
There is one well-known case of awarding Pakistani nationality to an Indian national in the recent past.
An Indian woman, whose husband died years ago, was granted Pakistani citizenship on the order of former interior minister Chaudhry Nisar Ali Khan in March last year.
Her citizenship application had been pending with the ministry since 2008. The woman had been married to a Pakistani man a long time back. After his death, her stepsons allegedly deprived her of her inheritance.
