The desire for a better life is sometimes so big that it makes people leave their countries and their families and work in other countries. They know that they will have to face difficult moments，that they won’t be able to communicate with the persons around them，and that maybe they will have to work in illegal conditions to get the money they need for their families，but they all take these chances and they hope they will succeed.

On the other hand，there are people who immigrate(移民)just for the sake of the people they love. They leave their families to make other families with the people they love. Women go to meet their men who have chosen other countries to start a new life，even if they miss their families and friends. Maybe they don’t have a place to work but they are able to wait to see what destiny(命运) has for them.

There are also the cases of the people who are forced to leave their countries because of a war which threatens their lives. They’d rather start from the very beginning again than risk putting their lives in danger.

When well­developed countries see that their homeland is being “invaded” by lots of immigrants，they set new laws that make immigration harder. As a result of this，many illegal immigrants cross the borders and are eager to work，although they are paid only half the amount of money native workers receive for the same kind of job.

The opinions of the local people are varied and they range from total refusal to complete acceptance. Immigrants in countries which have large communities of them are fighting for the recognition of their social rights and for equal treatment.

Many immigrants have managed to be fully accepted by the communities where they live and have managed to change the opinions of the local people about them.
