The actress left her native U.K. in the 1980s and went on to find fame in Hollywood with a role in hit TV sitcom Frasier.
Leeves admits she has been struck by the story of British pop star Cheryl Cole, who has been dropped from the U.S. version of TV talent show The X Factor, and she is convinced the singer's story is typical of many Brits who attempt to crack the States.
She tells Britain's Daily Mirror, "People in the U.S. haven't a clue who Cheryl is. I actually asked someone: 'Is she a pop star?' 'Yes, she is a huge star in the U.K., but nobody knows her here.'
"I do have sympathy for English people coming over to America. I went over when I was young and stupid, but now English people come over when they are already successful in Britain. It is so much harder for them. They don't have the time to pursue things.
"It is a fickle business, but I have worked very hard. I have always been a hard worker. You have to have faith it will work out. Now when I look back at my younger self, I think, 'My God, I was brave', but I'd never want to change anything because it's been so fantastic."
