DONALD Trump admitted he will be staying away from the huge street protests on his UK visit.
But he will need to mind his manners while visiting the Queen on Friday the 13th. Here's what we know...
Will Donald Trump bow to the Queen?
The US President will be expected to bow to the Queen when he meets her on July 13, 2018.
Trump does have the option of performing a subtle bow, which is just a nod of the head.
Rupert Wesson, academy director of professional coaching etiquette company : "It is customary for men to bow, however this is a very subtle gesture and not exaggerated.
"The Queen is said to be quite relaxed about this."
First Lady Melania will be expected to give a small curtsy.
The first time the pair greet the Queen, they should call her Your Majesty.
But after the initial greeting, they should address her as Ma'am.
The Queen has met all the US Presidents who have taken office during her reign except Lyndon B Johnson.
Johnson became Commander-in-Chief following John F Kennedy's assassination.
When is he having tea with her on his UK visit?
The Queen will have tea with Donald and Melania Trump on the afternoon of July 13.
Mr Trump is expected to let the Queen take charge as she is known for pouring tea for her guests.
He will be treated to a Guard of Honour when he meets Queen Elizabeth II.
Since Trump's visit is not an official state visit, no other members of the Royal Family are expected to be present.
