An American judge will hear an appeal from a conservative think tank to unseal Prince Harry's immigration records after he boasted about taking drugs in his book.
Lawyers from the US Government will attend next Tuesday’s hearing in Washington DC after the Heritage Foundation sued to see how the Duke of Sussex was granted a US visa.
Past drug abuse can be grounds for denying a visa application to the States and has seen Brits banned from entering that include Amy Winehouse.
Nile Gardner, of the Heritage Foundation, said a hearing on his organisation's suit will be heard on 6 June.
He tweeted that "Prince Harry immigration records case will be held in Washington, DC Federal Court in front of a US Federal Judge".
The Foundation is trying to discover if the revelations in the Duke's memoirs Spare were documented in his visa application.
In the book, it was revealed Harry had taken cocaine, smoked marijuana and tried magic mushrooms.
Hundreds of Brits are banned from the US after over their drug misuse.
In 2019, Brit Isabella Brazier-Jones claimed she was banned from the USA for 10 years after admitting to snorting a line of cocaine two years prior.
The 31-year-old said she was immediately thrown in a jail cell and made to wait for 24 hours before being shipped back to Britain.
The Heritage Foundation argues if immigration officials did know about the royal's drug use, Harry's case raises questions over whether he was given special treatment because he is a prince and his wife is a TV star, which they insist would be illegal.
In January and during his Spare book tour, Harry often spoke about his drug use, revealing he first took cocaine at 17 while on a shooting weekend.
He also admitted to hallucinating during a celebrity-filled event in California and smoking cannabis after his first date with Meghan.
Visa applicants are asked by US officials: “Have you ever violated any law related to possessing, using, or distributing illegal drugs?”
Answering yes means it is likely the applicant will be denied entry.
