By the mid-19th century, native-born Americans began regarding immigrants with hostility, claiming they took jobs. The nativist Know-Nothing party formed to combat immigration. During the 1880s, the influx of immigrants led the government to enact the first anti-immigration laws excluding certain groups. Ellis Island opened in 1892 and processed over 12 million immigrants from around the world over 60 years, inspecting them physically and legally before allowing entry to the country. The Chinese Exclusion Act of 1882 specifically placed a ban on Chinese immigration and remained in effect for over 60 years.
