Immigration has always been difficult. When people immigrate, they leave behind their friends, families, and culture. They also have to sell what they have, like a house, farm, or anything else too big to bring.
Travelling can also be very expensive. Many immigrants have to use all their money to pay fees or plane tickets.
Once immigrants arrive in the new countries, they can face many difficulties. They may have to get a job, find a house, and learn a new language. Immigrants can also be victims of racism.
