LONDON (AP) — Prince Harry, the son of King Charles III and fifth in line to the British throne, has formally confirmed he is now a U.S. resident.

Four years after Harry and his American wife, Meghan, the Duchess of Sussex, decamped to a villa in Southern California, a travel company he controls filed paperwork this week informing British authorities that he has moved and is now “usually resident” in the United States.

The formal acknowledgment underscores the prince’s increasing estrangement from Britain, after he and Meghan walked away from royal duties to pursue lucrative media deals in America. Since then, Harry has repeatedly criticized the royal family, including allegations of unconscious racism that were included in a Netflix series and the prince’s autobiography, “Spare.”

The paperwork was filed by Travalyst Ltd, a company at least 75% owned by Harry and which was founded in 2020 to “to promote global awareness of the importance of sustainable tourism.” The documentation was received Monday by Companies House, the government agency that oversees the incorporation of U.K. companies.
