I'm thinking about requesting some C=Files ('C' means the Certificate of Naturalization number) from the US Customs and Immigration Service before their fees increase. Are the files likely to have anything interesting in them? I have found the DOI, Cert. of Arrival, Petition and Naturalization Certificate for many of my relatives on Ancestry. Will there be additional docs in the files?
