Does anyone know where to find friends from other countries? Should I use dating sites or something?

Actually, dating sites are a great way to find friends, that's true. You can use different services, and if you're willing to find people from other countries, I can recommend you check out coomeet.com/chatroulette. I managed to find a girl from Europe there, and she's really nice. I'm sure you'll manage to find someone there as well.
