President Donald Trump on Tuesday, December 16, signed a proclamation further restricting entry into the United States for nationals of countries identified as high risk due to what the White House described as persistent and severe deficiencies in screening, vetting and information sharing that threaten national security and public safety.

Among the 15 additional countries placed under partial entry restrictions is Nigeria. The decision was announced in a fact sheet published on the White House website on December 16, 2025, titled “President Donald J. Trump Further Restricts and Limits the Entry of Foreign Nationals to Protect the Security of the United States”.

The White House said the move was aimed at strengthening national security through what it called common sense restrictions based on data.

The proclamation maintains full entry restrictions on nationals from the original 12 countries previously listed under Proclamation 10949. These countries are Afghanistan, Burma, Chad, Republic of the Congo, Equatorial Guinea, Eritrea, Haiti, Iran, Libya, Somalia, Sudan and Yemen.
