British royal officials say Prince William and his wife, Kate, are traveling to the United States next month on a trip that includes visits to the National September 11 Memorial and an NBA basketball game.

The visit, from Dec. 7 to 9, will be based in New York, although William will travel to Washington, D.C. on his own on Dec. 8 to attend a conference against the trade in illegal wildlife parts.

The Duchess of Cambridge will visit a child development center, accompanied by New York City's first lady Chirlane McCray.

The royal couple will both visit the Sept. 11 memorial, attend the NBA game and tour a youth organization together. The trip wraps up with a gala dinner at the Metropolitan Museum of Art.
