United States, Index to Alien Case Files - FamilySearch Historical Records

Record Description
This collection will include records from 1940-2003.

This is an index of Alien Case Files housed at the National Archives Regional Office in Kansas City, Missouri. Under the Alien Registration Act of 1940, immigrants in the United States were required to register and be fingerprinted. The Immigration and Naturalization Service (INS)—now the U.S. Citizenship and Immigration Service (USCIS)—drew up the Alien Registration form AR-2 to register aliens beginning in 1940. Immigrants mentioned in these files come from all over the United States. Files from aliens living in the immigration districts of Guam; Honolulu, Hawaii; Reno, Nevada; and San Francisco, California are housed in the National Archives Regional Office of San Bruno, California and are not included in this index.

 * Your ancestor may have used different names, or variations of their name, throughout their life. Be sure to check for those alternate names.

Using the Information
When you have located your ancestor’s record, carefully evaluate each piece of information given. These pieces of information may give you new biographical details that can lead you to other records about your ancestors. Add this new information to your records of each family. For example, you can use passenger lists to:


 * Learn an immigrant’s place of origin
 * Confirm their date of arrival
 * Learn foreign and “Americanized” names
 * Find records in his or her country of origin such as emigrations, port records, or ship’s manifests.

Tips to Keep in Mind

 * If your ancestor had a common name, be sure to look at all the entries for a name before you decide which is correct.
 * Continue to search the record to identify siblings, parents, and other relatives in the same or other generations who may have immigrated at the same time.
 * If your ancestor has an uncommon surname, you may want to obtain the record of every person who shares your ancestor’s surname if they lived in the same county or nearby. You may not know how or if they are related, but the information could lead you to more information about your own ancestors.

Unable to Find Your Ancestor?

 * Check for variant spellings of the name.
 * Look for an index in local historical and genealogical societies.
