What do immigrants often miss from their home countries?

Of course it depends on the person. People usually miss their families and their friends. They are also accustomed to the life in their home countries and the quality of life (good or bad). Many immigrants when they first arrive to a new country they usually know little to no people and that can become quite lonely. 

Since the time there were born it depends, there's fun violence, abuse, r@pe, kidnappings, threats, hostages ect.
