Prince Harry's U.S. visa application has been handed over to a judge, and President Joe Biden's lawyers have confirmed that they had complied with a court order to do so.

Under U.S. visa rules, applicants are asked about their criminal history and substance use. 

The Heritage Foundation filed a lawsuit against the fifth in line to the throne to determine whether he lied about his application for a full-time visa when he moved to California alongside his wife, the Duchess of Sussex, Meghan Markle. 

A filing for the think tank group said. "[The case] comes about in the main because HRH [His Royal Highness] voluntarily—and for immense profit—admitted in writing to the elements of any number of controlled substance violations.

The prince, 39, has admitted in his 2023 book to using various drugs, such as cocaine and psychedelics. 

He wrote, "Psychedelics did me some good as well. I'd experimented with them over the years for fun, but now I'd begun to use them therapeutically and medicinally."

Furthermore, he added that those substances let him redefine reality. He claimed that under the influence of these substances, he could let go of rigid preconceptions and see that there was another world beyond his heavily filtered senses, a world that was equally real and doubly beautiful.

In January 2020, the prince and his wife left their positions as members of the royal family and relocated to the U.S.

It will be decided whether or not to make the documents public after the review.

In a recent interview with GB News, Biden told Nigel Farage that they would have to see if they knew something about the drugs, and if he lied, they would have to take appropriate action. 

However, U.S. government attorneys have countered that although the prince acknowledged using drugs in the book, his statements "are not proof" that it happened.
