little diamond pearl question

well I got a simple question about pokemon diamond and pearl.

I have the european pokemon emerald and I want to import pokemon pearl or diamond, is it still possible to transfer my other pokemon to pearl even when I got the european version of emerald and the US version of pearl

maybe it's very common question but I still want to know for sure:P

Yes you can, actually. It's not region locked but language locked. So if you have the US D/P with a UK R/S then it should work, but not if one of them is the Japanese version.
