The Americans can't get their heads round domicile. Quite right too. It shows in this new Wall Street Journal article, to which I contributed.

For some flavour:

London also is a draw for many Americans. Morgan Maloney, 36, moved to London from New York last year with her banker husband and two young children. She lives in a house in Chelsea, a well-heeled neighborhood in southwest London known for its grand houses and proximity to the shops of Knightsbridge.

Ms. Maloney jokes with her husband about the number of Aston Martins, Maseratis and other flashy cars they see when strolling around the city. "New York is definitely a wealthy city but you encounter another stratosphere of wealth in London," she says. "I never thought I'd look back at New York and think what a bargain."
