It would be useful/interesting to know, which places are friendly, and which places have opportunities - specifically for digital workers (software, design, SEO, writing, media etc). If you've moved to a new place, please share your experience - visa problems, language barriers, xenophobic/racist issues, work permits, taxes etc
