United States, Index to Alien Case Files, 1940-2003

This is an index to 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 upon the 1940 Alien Registration Form (AR-2) to create Alien Case Files beginning in 1944. Immigrants recorded in these files come from all over the United States. Some 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 in San Bruno, California and may not be included in this index.
