Dear Mr. Droessler,
Thank you for posting your request on History Hub!
Foreign citizens who served with the U.S. Army during World War II and who were not officially inducted into the American Army were considered civilian employees by the U.S. Government. Official Personnel Files (OPFs) and medical information for individuals who worked for the U.S. government in a civilian capacity prior to 1952 are in the custody of the National Archives at St. Louis (RL-SL), P.O. Box 38757, St. Louis, MO 63138. Please include the full name used during Federal employment, date of birth, Social Security Number (if applicable), name and location of employing Federal agency, beginning and ending dates of Federal Service. For more information, the web site is https://www.archives.gov/st-louis/archival-programs/civilian-personnel-archival/index.html.
Due to the COVID-19 pandemic and pursuant to guidance received from the Office of Management and Budget (OMB), NARA has adjusted its normal operations to balance the need of completing its mission-critical work while also adhering to the recommended social distancing for the safety of NARA staff. As a result of this re-prioritization of activities, you may experience a delay in receiving an initial acknowledgement as well as a substantive response to your reference request from RL-SL. We apologize for this inconvenience and appreciate your understanding and patience.
We hope this is helpful. Best of luck with your research!
