According to Executive Order 14161, titled "Protecting the United States from Foreign Terrorists and Other National Security and Public Safety Threats," issued by President Trump on January 20, 2025, national security agencies conducted a robust assessment of the risks posed by various countries to the United States, including those related to terrorism and national security.

The Proclamation fully restricts and limits the entry of nationals from 12 countries found to be deficient in screening and vetting and determined to pose a very high risk to the United States: Afghanistan, Burma, Chad, Republic of the Congo, Equatorial Guinea, Eritrea, Haiti, Iran, Libya, Somalia, Sudan, and Yemen.

The Proclamation partially restricts and limits the entry of nationals from 7 countries that also pose a high risk to the United States: Burundi, Cuba, Laos, Sierra Leone, Togo, Turkmenistan, and Venezuela.

The Proclamation includes exceptions for lawful permanent residents, existing visa holders, certain visa categories, and individuals whose entry is deemed in the U.S. national interest.

Attention：This policy will go into effect in the early morning on Monday, June 9, 2025.

According to the U.S. Government Proclamation, the reasons for the full suspension for Sudan are: Sudan lacks a competent or cooperative central authority for issuing passports or civil documents and does not have adequate screening and vetting measures. According to the Overstay Report, Sudan has a B1/B2 visa overstay rate of 26.30% and an F, M, and J visa overstay rate of 28.40%.
