Sylwester was detained by ICE in Pennsylvania on August 20, 2026, and is being held in a detention center away from his family in Brooklyn. His wife, Mariya, is raising funds for a licensed immigration attorney and an ICE bond ahead of his first court hearing scheduled for September 2, 2026. The family says they could not find pro bono legal help in Pennsylvania on short notice and describes Sylwester as the backbone of the family.
