Dear Mr. Earnest,
Thank you for posting your request on History Hub!
We searched the Subject Index to Correspondence and Case Files, 1906 - 1957 in the Records of the Immigration and Naturalization Service (Record Group 85) and located an index card for Frank Szcsepansk listing file number 54709-422. This file is in the record series titled Subject and Policy Files, 1893 - 1957 which is also in Record Group 85. These records are in the custody of the National Archives in Washington, DC - Textual Reference (RDT1). To access these records, please contact RDT1 via email at email@example.com.
We hope this information is helpful. Best of luck with your family research!
