Many people move because of immigration. America was built up by immigration. Immigrants are people who settle in a place they don't come from or weren't born in. Some of the immigrants came form countries like Europe. Most people are Native in America. When people from other countries came to America there were African slaves they only became free after the civil war. Some people came to America because they were poor and were interested in the new land. When people got to America they realized they had more freedom than in their own countries. Over the next few hundred years more immigrants go t atracted to America and made teir families grow larger and larger. Illegal immigrants have become a large deal, people visit countries or move their have to be able to get an immigration before entering the country if they do not get their immigration it would become a LARGE problem. People in America say that everyone should build up their citizenship there. I think this is why people move.
