United States came into effect at 00:00 ET (05:00 BST) on Monday. The order, which Trump signed last week, restricts the nationals of Afghanistan, Myanmar, Chad, Congo-Brazzaville, Equatorial Guinea, Eritrea, Haiti, Iran, Libya, Somalia, Sudan and Yemen from entering the US. Nationals from a further seven countries - Burundi, Cuba, Laos, Sierra Leone, Togo, Turkmenistan and Venezuela - will face partial travel restrictions. The US president said the list could be revised if "material improvements" were made, while other countries could be added as "threats emerge around the world".

It is the second time Trump has ordered a ban on travel from certain countries. He signed a similar order in 2017 during his first term in office. The White House said these "common sense restrictions" would "protect Americans from dangerous foreign actors". There are a number of people from affected countries who may still be able to enter the US due to a number of exceptions. The order does not apply to:

·         "Lawful permanent" US residents

·         Their immediate family members who hold immigrant visas

·         US government employees with Special Immigrant Visas

·         Adoptions

·         Dual nationals when the individual is not travelling on a passport from one of

the affected countries

·         Afghan nationals holding Special Immigrant Visas

·         Holders of "immigrant visas for ethnic and religious minorities facing persecution

in Iran"

·         Foreign nationals travelling with certain non-immigrant visas

·         Athletes, their teams (including coaches and supporting staff), and their

immediate family when travelling for major sporting events, such as the

men's football World Cup in 2026 and the Summer 2028 Olympics in Los Angeles

·         In addition, the US Secretary of State may grant exemptions to individuals on

a "case-by-case" basis, if "the individual would serve a United States

national interest". (BBC)
