Family reunification
Family reunification is a recognized reason for immigration in many countries because of the presence of one or more family members in a certain country, therefore, enables the rest of the family to immigrate to that country as well.
Family reunification laws try to balance the right of a family to live together with the country's right to control immigration. A sub-case of family reunification is marriage migration, where one spouse immigrates to the country of the other spouse. Marriage migration can take place before marriage, in which case it falls under its own special category, or it can take place after marriage, in which case it falls under family reunification laws.
In recent years, there have been several cases of minors sent out on hazardous journeys in order to apply for political asylum status which, once granted, would enable the rest of the family to join them.
Family reunification in Europe
A major part of immigrants to Europe do so through family reunification laws. Many countries in Europe have passed laws in recent years to limit people's ability to do so.
