Trump is set to meet the queen. Here's what he shouldn't do.

As President Donald Trump prepares to make his first visit to the United Kingdom as president next week, one moment could outshine all others: his meeting with the queen.
"He's a massive Anglophile and he'll want to impress," Camilla Tominey, a royal expert and the political editor of The Sunday Express newspaper, told NBC News. "It's going to be quite a moment for him, and I don't think he's going to want to put a foot wrong."
The British government announced Friday that while there'll be no state dinner at Buckingham Palace, the president and his wife, Melania, are scheduled to meet Queen Elizabeth on July 13 at Windsor Castle.
Some, however, have voiced reservations about how Trump — who is not known for adhering to diplomatic niceties — will deal with the delicate issue of royal etiquette and protocol. After all, other high-profile visitors have attracted negative headlines for falling afoul of perceived etiquette breaches.
So how can Trump avoid a royal faux pas? NBC News spoke to etiquette and royal experts to find out the do's and don'ts of a royal meeting.
