“This new ban raises the number of banned nationalities to 93, 42% of those existing worldwide, and the total banned population to almost half of those who immigrated legally from abroad in 2024,” the Cato Institute report states.

The analysis cites a State Department memo obtained by Fox News, which lists no exceptions to the new policy.

The restrictions now affect countries in every region of the world, including Russia and several countries in Asia, Africa, and Oceania.

“African countries are the most represented on the list, with 39 nationalities affected, approximately 70% of African nationalities,” it adds.

It highlights that these African nationalities represent a large proportion of immigrant visa applicants, with almost 90% of applicants.

“In total, “324,000 legal immigrants would be barred by the policy, representing 48% of legal immigrants," the Cato Institute report specifies. At least 71,844 US citizens will not be able to reunite with their spouses and children under the new rule. The same will apply to 31,272 Green Card holders. 61,539 Americans will also be unable to reunite with their parents, while 55,414 will be prohibited from bringing other family members,such as siblings, into their homes.
