Chain Migration

Family Reunification: This refers to the immigration policy that allows for the families of immigrants who have settled in a new country to join them. It's one of the driving forces behind chain migration.

Push-Pull Factors: These are reasons why people leave their home country (push factors) and why they choose a specific country as their destination (pull factors). For example, economic opportunities can be both push and pull factors in chain migration.

Migration Stream: This term refers to the path taken by groups of migrants from their origin to their destination. In chain migration, there's often a well-trodden migration stream between specific towns or regions.
