i live in south america, lived in other country... After all you must know where you will live. Because you have a lot of " dreams " to your life in other country... Not is the same visiting "mode", than working or studding mode, because there are a lot of differences and the attitude of the people changes too. There are few or more laws to follow.. requirements, documents, to work or have a job... First of all go to VISIT the country that you want to live, stay a long period of vacation and ask... Before making a decision. The world is far to be a dream place and far to be perfect in all sides of the world are advantages and problems. Investigate first. and Ask to you want do you want in other country to live or stay.
