But it is possible the President - who owns two golf courses in Scotland - may make an unofficial visit before then, according to Government insiders.
The President said during the G20 summit in Hamburg last weekend that he and the Prime Minister had developed a "very special relationship".
Significantly, there was no mention of a Trump state visit in the Queen's Speech opening a session of Parliament due to last two years, suggesting the visit had been postponed until 2019 at the earliest.
Trump's visit was expected to happen this year, but senior government sources told Sky News that the commander-in-chief will not be in the country until next year.

"We'll be ready for Trump and his risky, divisive politics next year, and in the meantime we'll be opposing the free-market fundamentalism that May and her colleagues are trying to cook up in the UK-USA trade deal they are promising".
President Trump told the beleaguered Prime Minister in a phone call he didn't want to come if his arrival will be met by protests, a Downing Street adviser told the Guardian. The speech opened an extended two-year parliamentary session, sparking suggestions that Trump would not be landing in the United Kingdom any time before 2019.
