PRINCE Harry may be deported from the US if it is found he lied on his visa application, Donald Trump has claimed.
The Duke is fighting to stop the release of his immigration documents after being hauled to a Washington DC court over his drug use claims in memoir Spare.
Harry's admission that he took cocaine, cannabis and magic mushrooms mean he should not have been allowed into the US, the Heritage Foundation argue.
Releasing the application will prove if Harry, 39, lied about his alleged narcotics use which the think tank say is a breach of US federal law.
That, they argue, puts Harry's immigration status in doubt.
Lawyers for the US government insist drug claims in Spare "is not proof" he actually took them.

The Department for Homeland Security, which oversees immigration, say making Harry's documents public would breach his privacy.
But it an interview with GB News' Nigel Farage - to be broadcast tonight - Mr Trump said Harry "won't get special privileges" if it is found he lied.
The ex-US president said: "We'll have to see if they know something about the drugs...
"And if he lied they'll have to take appropriate action."

Mr Trump was unable to elaborate on what "appropriate action" meant.
But he added: "You would have thought they would have known this a long time ago."
Mr Trump - who will face Joe Biden in a race for the White House later this year - previously said he "wouldn’t protect" Harry because he had "betrayed the Queen".
Trump said if he wins the election in November then Harry "would be on his own".
The Duke wrote in Spare that cocaine "didn't do anything for me" when he took "a line" aged 17.

The 39-year-old added: "Marijuana is different, that actually really did help me."
After taking magic mushrooms, Harry said he started hallucinating and thought a bin in a bathroom was staring at him before growing a head.
