Officials have said that around 700 foreign students, out of a total of 1,400, have since left and Madrasahs have stopped enrolling more foreign students. But hundreds remain.
Interior Minister Aftab Ahmed Khan Sherpao told Reuters that foreign students might face "some administrative issues" in leaving by Saturday.
"As such, there is no deadline for them to leave, but we want them to go back to their countries as soon as possible."
Sherpao said the government was not considering forced deportation of those who failed to meet the deadline. "What action can we take against those students? The managements of the Madrasahs are responsible to arrange departure of their students, and we are pushing them to help us in implementing our decision."
MADRASAS VOW TO RESIST: Ghulam Rasool, a senior cleric at the Ittehad-e-Tanzeemaul Madaris (the alliance of organisations of religious schools) told Reuters that students and Madrasah managements would resist any deportation.
"Not one foreign student wants to go back," he said. "They will give themselves up for arrest if the government uses force."
Officials in Sindh say they have cancelled visas of 92 foreign students still at Madrasahs.
Sindh government spokesman Salahuddin Haider said foreign students might take seven to eight days to leave. "They need flights to go back and it will take some time."
Ghulam Rasool said the government move was aimed at "pleasing European countries and the United States". "The students should be given a chance to complete their studies; it's their basic right," he said.
