Visiting vs. Living in a new place

Try visit the place you're interested in moving to if it's feasible. Because working in a country or city is not the same as vacationing there. 

While hitting the tourist hot spots is great, try to explore neighborhoods where the locals live, visit grocery stores, and sit in restaurants. Then you can do one better and speak to other expats who live there to get a sense of what day-to-day life is like.
