Dear Mr. Kurek,
Thank you for posting your request on History Hub!
An important point of differentiation - is it a Certificate of Citizenship or a Certificate of Naturalization? Certificate of Citizenship indicates that the individual was deriving citizenship from a parent, while Certificate of Naturalization indicates the individual was applying independently to obtain citizenship.
If it is a Certificate of Citizenship, there wasn’t the standard naturalization paperwork (declaration, petition, etc) involved in the process - it truly was just an application that was submitted. Unfortunately, in this time frame of Immigration and Naturalization Service (INS) record-keeping, it is unlikely that you will be able to track down a copy of the application. It is possible that a Certificate File (C-File) or other INS file could exist, but it is unlikely. Your best paperwork option is going to be the documentation for the parent the individual was deriving citizenship from as this would have been that individual’s proof of eligibility to obtain their certificate.
If you want to know definitively what INS created/maintained on the individual, you will need to submit an Index Search request through the US Citizenship and Immigration Services (USCIS) Genealogy Program (www.uscis.gov/genealogy).
We hope this is helpful. Best of luck with your family research!

I have to disagree with one point in the other reply here, specifically
"Unfortunately, in this time frame of Immigration and Naturalization Service (INS) record-keeping, it is unlikely that you will be able to track down a copy of the application. It is possible that a Certificate File (C-File) or other INS file could exist, but it is unlikely."
The inquiry describes a situation where a C-File should certainly exist. It refers to a 1930 Certificate of Citizenship, which on its face refers to an application number rather than a petition number because the records behind the certificate are in the C-File with INS, now USCIS. Beginning 1929, Certificates of Citizenship were issued to both those who derived US citizenship through he naturalization of a parent and to women who derived citizenship by marriage prior to 1922. C-Files housed this material for Certificates of Citizenship issued 1929-1944.
To obtain that C-File this researcher can request it directly from USCIS Genealogy Program because they have the C-File number on the face of the certificate in their possession (so they don't need an index search). The C-number on the certificate in this case should begin with a letter "A" (not to be confused with an A-number). They would be wise to include a copy of the certificate with their request.
