I've definitely heard from people who fled Afghanistan because they were unsafe there, and also felt unsafe in Pakistan. The biggest difficulty that Afghans in Pakistan are facing is that they can't live here. Other witnesses have talked about how you only get a 60-day visa, so you're in this constant cycle of trying to renew your visa. If you don't have a valid visa, you can't rent a place to live and you can't get a SIM card. You actually can't leave the country without getting special permission to leave the country if you're undocumented.
People are looking at a situation.... People have made it here and they have no pathway to any other country, so they're living permanently in this situation. They can't send their kids to school and they can't work. I think many Afghans are going back to Afghanistan because they're running out of money and they can't feed themselves. At least if they go back to Afghanistan, they'll hopefully have family members who will take them in.
The biggest problem is that they can't actually survive here.
