Pakistan’s government said the move was due to security reasons and not aimed at Afghans, even though Afghans make up the majority of migrants and refugees in the country.
“Our policy is only about … individuals who are here illegally, no matter what their nationality is,” a government spokesperson said.
“The government says to go back, even though we have these cards. This level of problem has never happened in the past,” the man told BBC.
Since the announcement, at least 250,000 Afghans have already left Pakistan.
Many of them told Reuters that they felt compelled to leave even if they had documentation because they were scared they would be separated from undocumented family members
On Nov. 1, security forces started launching raids to arrest and deport undocumented foreigners.
The crackdown has been widely criticized by human right groups, who say that minorities such as girls, women and journalists, face high risks if they return back to the Taliban-ruled Afghanistan.
Since taking power of Afghanistan’s government, the Taliban has increasingly restricted women’s rights, including banning girls from going to high school and university.
The influx of refugees is also putting pressure on Afghanistan, which is already struggling due to international sanctions and foreign aid cuts against the Taliban.
