The couple, known as the Duke and Duchess of Cambridge, will hold a black time dinner to introduce young British film talent to Hollywood decision makers.
They will also meet with inner city youth and military families and attend a charity polo match in Santa Barbara. William will play and Middleton will award the trophy.
The three day visit, from July 8-10, will be Middleton's first trip to the United States. It will follow a longer trip to Canada.
