RAFIQ is a worried man these days. After 16 years in Karachi, where he works as a domestic servant, he is now struggling to put together some money to take his wife Aqlima and two-year-old son Arif back to Bangladesh, his homeland. The reason: the Bhutto government's recent decree that around two million immigrants must prove that they are legal residents or face deportation within six months. "All foreigners in Pakistan shall have to obtain a work permit or face expulsion within six months," says Interior Minister Naseerullah Babar, adding that more than 800 Bengalis have already been deported this year. Like thousands of other Bengalis, Rafiq is also being brutally hounded. "I cannot go out," says Rafiq. "If I get caught, what will happen to my wife and child. Who will feed them?"
