Germany! Yeah, I feel you on the socially "stuck" part. I've been over here almost 6 years and it took at least 3 to get a social life going. Perhaps I'm just not outgoing enough, perhaps there are a lot of other factors at play. I would say that making friendships in US is a lot easier on the whole, but this is based on anecdotal experience and not any sort of hard evidence. There are many US immigrants here who echo similar experiences. I found my first good friends were also immigrants and then later made a few close German friends.
