Developer/programmer here.<p>By circumstances I mean: wife and kids, age, skills.<p>I live in Brazil and I really would like to leave this country and definitely live in another place. I don't have any preferences for the place right now and I accept suggestions.<p>My main issue on immigrating is to be accepted given my age (37) and family. AFAIK, having an effective job proposal and employer sponsorship is the only way for many countries. Do you know anywhere where people can go on business or as tourist and apply for jobs?
Search for EU Blue Card, now available in most EU countries. Germany's version of the Blue Card includes the availability of a separate visa that lets you spend 6 months in Germany to look for a job (of course, it's also possible to get a job before entering the country).
