Dear Iram Gomez,
Thank you for posting your request on History Hub!
Official Military Personnel Files (OMPFs) and medical records of officers and enlisted personnel of the U.S. Marine Corps who were separated from service after 1904 and prior to 1957 are considered archival. Theses OMPFs are located at the National Archives at St. Louis (RL-SL), 1 Archives Drive, St. Louis, MO 63138-1002. Please use a GSA SF 180 to request these records. Certain information in the records is not available to the general public without the written consent of the veteran or his next of kin.
We hope this is helpful. Best of luck with your research!
