The document discusses immigration to the United States in the late 19th century. It notes that new immigrants faced resentment from earlier immigrants and nativists, who disliked that the new immigrants would not quickly assimilate and remained in ethnic enclaves. Laws like the Chinese Exclusion Act aimed to restrict immigration. Ellis Island opened in 1892 to screen immigrants from Europe and hold them for examinations before releasing them into the US. The growth of cities drew many immigrants seeking jobs in factories. Settlement houses aimed to help immigrants assimilate and address urban poverty through education and social services.
