US President Donald Trump has signed a proclamation to ban entry of individuals from 12 nations — Afghanistan, Myanmar, Chad, the Republic of the Congo, Equatorial Guinea, Eritrea, Haiti, Iran, Libya, Somalia, Sudan, and Yemen — citing national security and public safety threats.

Trump has partially restricted and limited the entry of nationals from the seven nations: Burundi, Cuba, Laos, Sierra Leone, Togo, Turkmenistan, and Venezuela. According to the White House, these restrictions distinguish between, but apply to both, the entry of immigrants and nonimmigrants.

Trump even stated that the US must be vigilant during the visa-issuance process to ensure that those aliens approved for admission into the US do not intend to harm Americans or the national interests of the US. Trump noted that the US must ensure that admitted aliens and aliens otherwise already present in the US do not bear hostile attitudes toward its citizens, culture, government, institutions, or founding principles, and do not advocate for, aid, or support designated foreign terrorists or other threats to national security.
