Diversity. Usually the Americans are quite well-liked if I might say so myself. In CBB5 the Top 3 weren't British.

It's pretty much about who they can get, who would be liked, and who would be interesting. Verne, Coolio, and Latoya have all provided us with some entertainment this series, Dirk and Jermaine placed 3rd and 2nd in 2007, Traci is still a CBB favorite of many, and Brigitte/Caprice did well in their season.

Plus, the United States is one of the biggest sources of output from the entertainment industry, so there's bound to be some Americans. India, who has Bollywood which produces more films than Hollywood a year, has had Shilpa but I'm not sure how many Indians would want to go on Celebrity Big Brother after what happened.
