Immigration detention

Immigration detention involves incarcerating foreign nationals, asylum seekers, and immigrants suspected of unauthorized entry or visa violations in detention centers. This practice serves immigration control, pending visa decisions or repatriation. Mandatory detention compels the imprisonment of individuals deemed illegal immigrants or unauthorized arrivals. While some countries impose maximum detention periods, others allow indefinite detention. The detainees are held until immigration authorities decide whether to release them or deport them back to their country of origin.
