You have to know that there are two type of visa to go any country you can choose either of them. One is the temporary visa type in which you will get the permission to enter and live in a foreign country for a limited time. You cannot live there more than that period because it will consider illegal to stay after that. Most of the time the temporary visa is working and it should be renewed after sometime. The renewal time is different of different countries so you should be aware about it before you get that working visa. Other than that there is a visa for visit and it is for a very short time which is usually less than a year. In this visa you cannot work there but you go to visit your relatives or for enjoying the travelling.
