On December 16, 2025, President Donald Trump issued a proclamation titled “Restricting and Limiting the Entry of Foreign Nationals to Protect the Security of the United States”, which updated and expanded partial and full suspensions of entry into the U.S. for nationals of various countries (see: https://www.whitehouse.gov/presidential-actions/2025/12/restricting-and-limiting-the-entry-of-foreign-nationals-to-protect-the-security-of-the-united-states/). This market will resolve to "Yes" if Donald Trump issues any executive order, signs any bill into law, or if the Trump administration otherwise takes any formal action which is aimed at fully or partially suspending entry into the U.S. for nationals of any specific, additional country between market issuance and the listed date, 11:59 PM ET. Otherwise, this market will resolve to "No". A qualifying action must be aimed at restricting or banning entry into the United States for nationals of a particular country or countries. Blanket actions to restrict entry for individuals holding certain visa classes, or other generalized entry restrictions, which do not target a specific country or countries, will not count. Additional country refers to any country not subject to a full or partial suspension of entry as of the December 16 proclamation. Any qualifying government action taken within this market’s timeframe will qualify for a "Yes" resolution, regardless of when the policy takes effect. However, announcements of future or planned bans which are not made official through government action will not qualify. Any action meeting these criteria will count, even if its implementation is immediately halted or delayed by judicial or other actions. The primary resolution source for this market will be information from the US federal government; however, a consensus of credible reporting will also be used.
