I've just started to explore details about tenses. And one point doesn't take me a clear understanding. Maybe this is not about tenses at all.
So. There is a few examples, and I don't really get, why first is using "in", and other using "to".
1 (In)
Have you always lived in Chicago?
How long has your sister been in Australia?
2 (To)
Have you been to California?
They've been to Japan.
I've thought it's about a scale of place or something, but it's not(Japan is a country but using with "to"). Maybe it's about accent on time(1)/place(2)?
