Foreign students studying in around 400 seminaries have yet to get documents from their countries certifying that their governments have no objection to them studying in Pakistan, and this may lead to their expulsion from the country. Official sources told Daily Times that the Interior Ministry had sent letters to 51 countries through the Foreign Office seeking confirmation that the students were their nationals and asking them to state in writing that they have no objection to their nationals studying in Pakistani madrassas. This condition was put in place after the July 7, 2005, bombings in London by British nationals of Pakistani origin. Pakistan was mentioned in connection with the bombing after it emerged that one of the bombers had spent time at a madrassa here. Following the attack, President Gen Pervez Musharraf announced that foreign students would be sent home. The sources said that around 1,200 foreign students had been deported since then, but around 800 foreign students were still studying in seminaries in Pakistan. The federal government decided not to grant visas to foreigners wishing to gain admission to Pakistani seminaries.
