Future royal Meghan Markle has given up her current charitable commitments and will focus on getting to know the UK and touring the country with Prince Harry.
The American star, who has worked with World Vision Canada and as a UN women's advocate, has stepped away from the roles in order to start her royal life with a "clean slate".
Former Suits actress Ms Markle, who will wed the Queen's grandson at St George's Chapel, Windsor Castle in May, will join Harry in travelling around different towns and cities ahead of her nuptials, Kensington Palace said.
"She wants to spend this time learning about the UK.
"This is the country that's going to be her home now," Harry's Communications Secretary Jason Knauf said.
Her introduction to the UK begins with an away day to Nottingham on Friday, her first official royal engagement.
Her commitment to becoming a full-time royal was clear when the Palace confirmed she will become the fourth patron of the Royal Foundation of the Duke and Duchess of Cambridge and Prince Harry after the wedding.
It is likely to be renamed, depending on which dukedom Harry is given on the morning of his wedding by his grandmother the Queen.
The Foundation is behind programmes such as the Heads Together mental health campaign.
Mr Knauf said Ms Markle was behind the decision to end her current charitable work before she begins her working with the Royal Foundation and carving out her own charitable interests.
"Ms Markle is incredibly grateful for the opportunities that she has had with World Vision Canada and the UN women," he said.
"She has, through the organisations, been able to meet incredible smaller organisations right around the world.
"But she has made the decision that she wants to start with a clean slate and focus on the UK, and getting to know this country, and travelling around the Commonwealth.
"So the only the role that she will begin with is as patron of the Royal Foundation.
"That has been a decision that she has taken."
He added: "This is the country that's going to be her home now and that means travelling around, getting to know the towns and cities and smaller communities."
