When immigrants come to the US they try to find work where ever they can. Sometimes they know where they can find jobs before they come, but if they come illegally they may not know where to find work. Many Americans think that all immigrants are stealing our jobs because some illegal immigrants will work for virtually no money, so that many companies will hire them to maximize profits. This is the same now as it was 100 years ago. Whenever jobs are hard to get, and people still come to the country and will work for little money, people will be angry about it.
