In his dreams, Aliaksei Shcharbachenia is on a plane with an immigration agent’s hands wrapped around his neck. When he wakes up, he’s freed from the memory of his traumatic and botched deportation attempt last month — but then he’s stuck languishing in Farmville, Virginia. The 35-year-old asylum-seeker from Belarus has spent nearly a year at Farmville Detention Center. There, he says, he’s experiencing medical neglect as a tumor grows on his arm.
