Since returning to the presidency, Donald Trump has once again made immigration control and border enforcement central to his administration’s agenda. Earlier this month, the U.S. government announced a major expansion of travel restrictions, adding countries to a growing list of nations facing full or partial bans on entry. With 39 countries now affected, this represents one of the broadest travel restriction regimes in recent U.S. history. The White House frames the policy as a national security measure, aimed at ensuring travelers do not pose threats, while supporters argue it pressures foreign governments to strengthen border controls. Critics warn of diplomatic tensions, economic disruption, and collective punishment of civilians.

Full travel bans now target countries including Afghanistan, Burma, Chad, Congo, Eritrea, Haiti, Iran, Libya, Somalia, Sudan, Yemen, and Syria, among others. Citizens from these nations face comprehensive visa suspensions with limited exceptions. Partial bans affect countries such as Angola, Nigeria, Tanzania, and Zambia, restricting certain visa categories. Officials assert that these measures respond to deficiencies in document security, information sharing, and compliance with U.S. standards. Yet governments and advocacy groups criticize the lack of transparency in how countries are evaluated.
