President Donald Trump has unveiled comprehensive travel restrictions affecting citizens from more than 20 countries, establishing what represents the most extensive border control measures implemented in recent American history. The presidential proclamation, announced Wednesday, introduces a multi-layered approach that could impact millions of individuals seeking to enter the United States for various purposes.
The Guardian reported that the new directive creates a three-tier system of escalating barriers, with complete prohibitions for some nations while implementing partial restrictions for others. The policy announcement comes nearly five months into Trump's second presidential term and significantly expands upon his previous immigration initiatives.
The proclamation specifically references the recent attack in Boulder, Colorado, where an Egyptian national attacked demonstrators advocating for the release of Israeli hostages in Gaza. The directive also builds upon Trump's initial executive order requiring the State Department to identify countries with inadequate vetting procedures.

Travel ban mechanisms
Travel restrictions function by limiting or completely prohibiting entry for nationals from designated countries. These measures can encompass total visa suspensions or target specific visa categories, depending on the perceived security risks.
The president's initial executive order mandated that the State Department identify nations "for which vetting and screening information is so deficient as to warrant a partial or full suspension on the admission of nationals from those countries." This foundational directive established the framework for the broader restrictions announced Wednesday.
Presidential proclamations differ from executive orders in their scope and implementation. While executive orders provide direct instructions to federal agencies, proclamations typically signal broader policy shifts and can carry legal weight during national emergencies.
Complete entry prohibitions
The most restrictive category applies total bans on both immigrant and non-immigrant travel for nationals from 13 countries. These nations face absolute prohibitions on US entry:
Afghanistan, Myanmar, Chad, the Republic of the Congo, Equatorial Guinea, Eritrea, Haiti, Iran, Libya, Somalia, Sudan, and Yemen comprise this list of completely restricted countries.
Partial travel limitations
Seven additional nations face partial restrictions rather than complete bans. Citizens from Burundi, Cuba, Laos, Sierra Leone, Togo, Turkmenistan, and Venezuela encounter specific limitations on their ability to enter the United States.
These partial measures allow for case-by-case evaluations while maintaining heightened scrutiny of applicants from these regions.
The proclamation cites multiple factors contributing to each country's inclusion. National security concerns form the primary basis for these designations, though specific rationales vary by nation.

Several countries, including Afghanistan, Eritrea, Somalia, Sudan, Yemen, Libya, and Venezuela, lack reliable central authorities capable of properly issuing passports or conducting adequate screening of departing nationals, according to the proclamation's findings.
High rates of visa overstays characterize another group of restricted nations. Myanmar, Chad, the Republic of Congo, Equatorial Guinea, Eritrea, Haiti, Burundi, Laos, Sierra Leone, Togo, and Turkmenistan all demonstrate significant problems with individuals remaining beyond their authorized stay periods.
Terrorist activity and state-sponsored terrorism represent the third major justification category. Iran, Afghanistan, Libya, Somalia, and Cuba all face restrictions due to their connections to terrorist organizations or activities.
Distinctions from the 2017 measures
The current restrictions significantly expand beyond Trump's initial 2017 travel ban, which originally targeted seven predominantly Muslim countries before including North Korea and Venezuela. This new proclamation encompasses a broader geographic scope and introduces Haiti as a notable new addition.
Afghan refugee implications
The inclusion of Afghanistan presents particular complications given that many Afghan refugees approved for US resettlement had assisted American military forces before the 2021 withdrawal. These individuals faced persecution risks due to their cooperation with US troops during the extended military presence.
The Taliban withdrawal agreement, negotiated during Trump's first presidency, established the framework for the complete US military departure in 2021. Many Afghans who worked alongside American forces subsequently sought refuge through established refugee programs.
Homeland Security Secretary Kristi Noem announced "the termination of temporary protected status for Afghanistan" last month, with the designation ending May 20, The Guardian reported. This decision affects thousands of Afghans currently residing in the United States under protective status.
Implementation timeline
The proclamation takes effect immediately upon signing, though specific implementation details remain under development. Federal agencies must coordinate to ensure consistent application of the new restrictions across all entry points.
Processing of pending applications from affected countries will likely face significant delays as officials review cases under the new criteria. Individuals currently traveling or with approved travel documents may encounter complications depending on their country of origin and travel purpose.
The State Department and Department of Homeland Security will oversee enforcement of these measures, working to establish consistent procedures across all US embassies and border entry points.
