Prince Harry could be DENIED entry to the US by border guard who has read ... trends now
Prince Harry could be denied re-entry to the US by any border official who was aware of his drug-taking admissions in his autobiography, legal experts have claimed.
The border officials could grill him on the admissions if he failed to declare it on his visa application form.
It means the Duke of Sussex could be stopped from returning to the US next month after his trip to London as he sues Mirror Group Newspapers over allegations of phone hacking.
The revelations come after it emerged the US government will appear in a federal court next Tuesday to answer questions regarding Harry's visa application after he admitted taking cocaine, cannabis and magic mushrooms.
Washington DC-based think tank The Heritage Foundation is suing Joe Biden's administration to force officials into releasing the Duke's immigration files.

Raymond G. Lahoud, an immigration lawyer at Norris McLaughlin, told DailyMail.com that Harry could be barred from re-entering the US if he came up against the wrong border guard.
A CBP officer would not be able to quiz Harry on his previous drug use if he had declared it at the time of his visa application, since a decision would already have been made to issue a waiver.
It is not known whether Harry declared this.
'Every time he comes into the US he is supposed to go through Customs and Border Protection (CBP),' Mr Lahoud said.
'Any person would be asked those questions and would be turned away if there is a clear record of drug use [that has not previously been declared].
'If I am a customs agent, I have the right to answer whatever questions I want. If he has violated any law with regard to drug use, that's grounds to be turned away, regardless of whether there was a conviction.'
Mr Lahoud added that he thought it was unlikely to happen even if Harry had not declared his drug-taking because he was not a 'normal citizen' - and agreed with The Heritage Foundation's claim that he was 'getting special treatment because is Prince Harry'.
The think tank is arguing that an explanation of how Harry got into the US - despite subsequent admissions of drug use - is in the public interest.
It also wants to know how Harry answered questions about his drug use on his application.
The case is set to be held in front of a federal judge on June 6 at 2.30pm at the US District Court for the District of Columbia.
It comes after the the think tank failed to make the application public using freedom of information laws in March.
Mr Lahoud said the case 'could go either way', but added that he thought the privacy of immigration records would trump the public interest argument - and the files would not be released.
He did say, however, that there is a risk that the publicity generated by the lawsuit would 'put a big mark' on Harry's immigration file that could make it more difficult for him to renew his visa.
Mr Lahoud said if the Duke is found not to have declared his drug use on his visa application, it 'should be rescinded'.
