Prince Harry's security check 'focussed on three key areas' amid Duke's drug use admission

Chavin discussed Harry’s likely A1 visa, which is given to ambassadors, heads of states and members of the Royal Family and outlined the three key areas that are covered in the security check for that type of visa.

Asked by Cameron what kind of visa she thinks the prince has, Chavin replied: “I think that the visa Prince Harry is on is something that none of us see, and for me it is very uncommon and rare.”

However, for the Royal Family, Chavin said that it is the “most common” type of visa they think about.

“Do we need a visa to go to the United States? Yes of course. Which one? Oh, it's the A1, of course,” she said.

Svar then asked: “In terms of a security check, how does that differ to the everyday visa that most normal citizens would get to enter the US?”

Chavin replied: “I think there's a focus on only three areas: terrorism, contrary to foreign policy, and espionage. Just on the big headline level of what those ineligibilities might be. But yes, everyone else has a look at whether you violated a controlled substance or statute.”

The Duke of Sussex's US visa documents are at the centre of a court battle, since he admitted to taking illegal drugs in the UK and America in his memoir Spare.

The Heritage Foundation, a conservative think tank, is taking legal action against the Department of Homeland Security in a bid to force officials to release Harry's visa documents.

The organisation wants to see if the royal admitted to using illegal drugs before gaining a US visa.

Under US law, foreign nationals who have admitted to taking drugs can be turned away at the border and refused a visa.

However, disclosure of previous drug use does not automatically mean immigrants will be banned but they are legally obliged to declare whether they have taken drugs on their visa application.

Lawyers from the Biden administration have backed a statement from a US ambassador which suggested that the President would not deport Prince Harry.

Jane Hartley, America’s ambassador to the UK, was asked by Kay Burley on Sky News in April whether deportation was on the cards for the royal.

Hartley answered: “Well, it’s not going to happen in the Biden administration.”
