President’s sweeping proclamation targets citizens of many countries and would dramatically reshape US border policy

Nearly five months into his second term, Donald Trump announced a new sweeping travel ban that could reshape the US’s borders more dramatically than any policy in modern memory. The order, banning citizens of 12 countries, came into effect at 12am ET in a move Trump said would protect the country from “foreign terrorists”.

The proclamation represents one of the most ambitious attempts to reshape the US’s approach to global mobility in modern history and potentially affects millions of people coming to the US for relocation, travel, work or school.

A travel ban restricts or prohibits citizens of specific countries from entering the US. These restrictions can range from complete visa suspensions to specific limitations on certain visa categories.

Trump’s day one executive order required the state department to identify countries “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”.
