Officials are looking at whether to stage some or all of the July 13 trip away from the capital amid fears of violent demonstrations.
Mr Trump will hold talks with Mrs May, in a boost for the special relationship, officials confirmed yesterday.

But his opponents immediately announced plans to take to the streets in protest, with tens of thousands pledging to attend events.
As a result the US President could be kept out of London. Instead, he may meet the Queen or other royals in either Scotland or Windsor – although it will not be a state visit.
The Daily Mail revealed last Saturday that the long-planned event would take place in July and that Mr Trump would meet the Prime Minister in No 10 or at her country retreat, Chequers in Buckinghamshire.
Yesterday, Mrs May’s spokesman confirmed: ‘The President of the United States will visit the UK on July 13. He will hold bilateral talks with the Prime Minister during his visit.’
Foreign Secretary Boris Johnson tweeted that it was ‘fantastic news’ that the President was coming ‘at last’ and claimed it would be the ‘greatest visit ever’.
The announcement will come as a boost for relations between London and Washington after a series of clashes between Mrs May and Mr Trump. He was first invited to Britain when he took office last year, but the visit was delayed amid fears of mass demonstrations.
Yesterday, critics wasted no time in announcing they would hold huge protests against him. Guardian commentator and Jeremy Corbyn ally Owen Jones tweeted: ‘Official: Donald Trump is coming to Britain on Friday 13th July. EVERYBODY OUT ON THE STREETS!’
More than 30,000 people have already confirmed on Facebook that they will attend a protest hosted by a campaign group calling itself Stop Trump.
Liberal Democrat deputy leader Jo Swinson said her party would be ‘front and centre’ of demonstrations against the President, adding: ‘The Government has made the right decision to cancel Trump’s state visit but this scaled-down trip must not be met with scaled-down protests. Protesting against a man with dangerous, misogynistic and racist views is our responsibility.’
Kate Allen, UK director of campaign group Amnesty International added: ‘When Donald Trump arrives on these shores, we and thousands of our supporters will very definitely be making our voices heard.’
The President is expected to attend a Nato summit in Brussels on July 11 and 12 and travel to the UK afterwards.
Michelle Kosinski, senior diplomatic correspondent for CNN, tweeted: ‘British govt working on plans to possibly keep Trump’s big meetings OUTSIDE of London during his July visit, to minimise inevitable protests. Eg. Meeting with Queen could be at Windsor; with May at Chequers.’
The Bow Group, an influential Tory think-tank, urged Mr Trump to avoid London. Its chairman Ben Harris-Quinney said: ‘It is important that the people of the United States and its government know there are many in Britain who strongly support the President … and wish for President Trump to be afforded the warmest of welcomes. Sadly that will not be the case in London.’ Ministers are said to have discussed plans for Mr Trump to meet the Queen at Balmoral Castle and play a round of golf there.
Mrs May was among the first foreign leaders to visit him in the White House but he has so far not reciprocated. He pulled out of a working visit in February to open the new US embassy in London.
Mr Trump earned a rebuke from the Prime Minister after sharing anti-Muslim propaganda from far-Right group Britain First.
He also provoked London Mayor Sadiq Khan by suggesting he was not taking terrorism seriously.
Mr Khan last week warned Mr Trump to expect protests, saying: ‘I have no doubt if he does come, there will be some people who want to express their views loudly and peacefully to the President.’
Yesterday, he tweeted: ‘If he comes to London, President Trump will experience an open and diverse city … He will also no doubt see that Londoners hold their liberal values of freedom of speech very dear.’
Mrs May is keen to pave the way for a trade deal with the US after Brexit. She and Mr Trump spoke regularly over the chemical weapons attacks in Douma, Syria, and the poisoning in Salisbury.
Former US president George W Bush faced protests when he came in 2003, with millions of pounds spent on security to protect him.
Demonstrations erupted when Mr Trump went to Paris last July, but the visit was not affected.

Mr Trump has developed close ties with Emmanuel Macron of France.
He was invited to be guest of honour at the Bastille Day celebrations last year, when his 24-hour visit was topped off with a military parade.
He and his wife Melania dined with the French President and his wife Brigitte at the Eiffel Tower.
UK diplomats have become concerned about the French stealing a march on relations with the US.
This week Mr Trump hosted President Macron, the first state visit by a foreign leader since he entered the White House.
Ministers have discussed plans for Mr Trump to meet the Queen at Balmoral Castle before visiting one of his two golf courses in Aberdeenshire and Ayrshire.
Officials believe using the Royal Family’s remote estate would prevent embarrassing scenes where he is confronted by thousands of demonstrators.
Mr Trump is said to have expressed an interest in playing a round of golf at the Queen’s nine-hole course at the Aberdeenshire castle.
The President had been due to open the new £1billion US embassy at Nine Elms in south London in February.
He said he had dropped the visit because the old embassy in Mayfair had been sold on the cheap.
Jeremy Corbyn has said Mr Trump should not be invited and urged his followers to turn out in force if the US President visited the UK – to send him a ‘clear message’.
More than a million people signed a petition last year calling for the state visit to be cancelled.
