Genealogy: Using Historic Immigration Records to Research Your Ancestors

The United States is a country built by immigrants. The beginning of European settlement in what is now the U.S. also marked the beginning of immigration here. The origins of these immigrants have changed over time, from English to Irish to German to Chinese to Eastern European to Italian to Asian to Hispanic. Many came to the U.S. in the hopes of a better life. They sought religious freedom, a better economic situation, or something else.

Most residents of the U.S. today are either immigrants themselves or descended from immigrants. Below is an overview of what kinds of immigration records are available for family history research and where to find them.

What the Records Are

There will in general be more information on the lists the newer they are.
