Of course, your mileage may vary, but some schools will be more impressed the diversity that you bring to campus than others. Of course, a lot depends on what that diversity means. For example, there is at least one US military base in the country in which I live. Occasionally I see students apply from there, who, while they have lived in many different countries, have always lived on military bases, and in some cases, rarely left them. Those applicants do not bring the experience of living around the world. They have lived in an American monoculture delivered in multiple nations.
