3rd world immigration

There are many opinions about 3rd world immigration. Some people agree with that and the other people do not agree with this phenomenon. In my opinion, there are many problems of 3rd world immigration. First of all, these people can cause crime like murder, stealing, and so on. This is very serious issue on The United States. If these kinds of crime happen consistently, people feel uneasy and the atmosphere of this society would become worse. Also there will not be any orders and roles in this society. It would threaten many people not only in The United States, but also in many other countries. Second, there is a problem of job losses because of the cheaper labor forces from the 3rd world immigrants. If the cheaper work forces rush like a flood, many American labors loss their jobs because companies want higher effect with lower investment. Therefore, they prefer 3rd world immigrants work forces to American labors.
