Beginning January 1, 2026, the US administration is implementing a partial or total ban on foreign nationals from 39 countries. This proclamation, issued by President Trump on December 16, 2025, expands on a previous ban from June 2025. The restrictions categorize countries into 'full suspension' and 'partial suspension' categories, with several African and Middle Eastern nations added or moved to stricter categories. The ban affects visa issuance and entry for nationals of these countries.
