That might suggest that British English is only spoken by a small number of people, in one country, and everybody else speaks one other different version. Not so. It is just as correct to say "There is a fairly big difference between the English used in America and that used in the rest of the world."
Anyhow, in both variants of English, "clear to me" is overwhelmingly the majority usage. "Clear for me", although not incorrect, is used very much less often.
