Ask HN: Change Country to Ease Bootstrapping?

I might soon take the plunge and start working on a few startup ideas full-time (bit of saved money), and I was wondering whether I should do this from another country. Being European, moving around there doesn't cause any big legal complications. I live in Bavaria, Germany, and while it's a really nice place (especially after spending quite some time in New Jersey recently), it ain't exactly cheap. Going east and/or south would probably make for cheaper rents and a generally lower cost of living. As I still could aim my business (and possibly small contract jobs) at higher-paying economies, this seems like a good way to stretch my savings and thus give me more time to focus.

Still, I wonder whether getting accustomed to a new country, learning the language etc. won't distract too much.

So it would be great if anyone has some experiences about that, or has some nice cities/countries to recommend…
